USING THE IN-BUILT CODE-SET
When the board is first powered on, it contains a pre-loaded code set.
This matches the MAME default key codes as the table above indicates.
For many users there is no need to do any re-assignment, just power up
and play.
You may want to re-program the
codes if any of the following
apply:
· You use an
emulator or other PC application
without a key re-mapper.
· You don't want
people to be able to access the
MAME game config menus by using shift buttons (for example game
contests etc)
· You want to limit
coin insert to a real coin slot
rather than using shift button feature.
Installation
The board automatically detects
which interface it is connected to (USB
or PS/2).
You do not need to install any
drivers or software from the
Ultimarc CD to get the board to operate.
Connect
one side of each switch
to the screw terminals as
indicated on PCB. "Daisy chain" the other side of all switches together
and connect to either of the "GND" terminals on PCB. Some
micro-switches have 3 connections – only use the ones marked
"NO" and "COM". Don't connect anything to the "NC" tag. Below is a
diagram showing an example of 3 joystick micro-switches connected to
inputs on the I-PAC board.
The
gauge of wire used is not
critical. Any insulated stranded
wire will do providing it is thick enough to be gripped by the screw
connectors. The wire we supply in our wiring kit is 16 X 0.2 mm.
You can connect more than one switch to one I-PAC input, to perform the
same function. For example you might want to have side flipper buttons
connected to the same inputs as fire buttons as these are used in
different games. This applies to joysticks too. You can connect a 4 and
an 8-way stick to the same inputs. (But check our 4-8 way switchable
sticks though!)
If
you are using the LED
harness, plug it onto the 10 pin
header. Note that one pin of the header is missing. This is to ensure
the polarised plug can only be inserted the correct way round.
Plug
one end of cable into DIN
connector marked "PC" and other
end to motherboard keyboard or USB connector. Connect normal keyboard
to connector marked "KBD" (optional and does not apply in USB mode, you
can leave the keyboard "as-is".)
If
using USB: Start windows.
With Windows running plug in the
USB cable. Windows will detect the device and automatically load
drivers. The drivers for this device are on the Windows CD ROM.
There
are no Ultimarc drivers for the I-PAC.
BASIC
TESTING.
Boot PC into DOS or Windows and
run a text program such as Notepad.
Observe the LED on the I-PAC should display a flash pattern and then
light continuously.
Press various player 2 buttons (some of the player 1 buttons are mapped
to non-displayable codes such as ALT so best to use player 2). You
should see characters displayed, just as if they were typed on the
keyboard.
ADVANCED TESTING (optional)
If in DOS, enter COPY CON to
suppress the command prompt. On a keyboard
plugged into the pass-through, press CTRL-ALT-P. (press and hold each
key in this order). Enter "T" in the menu to enter test mode. All
pressed buttons and joysticks will be displayed on the screen. The
input will be shown, followed by the code which is currently assigned,
followed by the shifted code, if one is assigned. Test all buttons and
joystick switches. If all OK reboot to exit. Now ready to play!
PROGRAMMING
(optional)
There
are two methods of
programming the board. The WinIPAC
IPD utility can be downloaded and run from Windows or IPACUTIL in DOS
See programming
instructions
for details, OR you can enter the Interactive Programming and Test Mode
by pressing CTRL-ALT-P on a keyboard connected to the pass through. See here for
instructions. You might also have to do some setting-up in MAME because
buttons 5 and 6 are not normally assigned by default in MAME and must
be programmed. (press tab in any game).
In USB mode, the I-PAC supports left/right mouse buttons plus volume
up/down, power, sleep and wake, in addition to keyboard keys. All of
these functions can be assigned to any control. The shifted code set
(see below) is particularly useful for assigning the function controls.
SHIFT
MODE
Pressing and holding 1player
start enables shift
mode with access to the following keys (when "MAME" setting is used):
2
player start=Esc – for
jumping
back to the menu
Joystick
left=Enter – for
running
games in Windows and for MAME game config menu
Joystick
right=Tab – for
entering
MAME config menu
Joystick
up=~ - for entering MAME
volume/gamma menu
Joystick
down=P MAME pause key
1
fire (button 1)=5 –
for
simulating coin insert.
The above shift keys can be changed/turned off as required if the board
is programmed.
MAME
HINT: to get past "Type OK
to continue" prompt, just move
joystick left then right.
NOTES:
PC should pass BIOS keyboard
self-test with or without a normal keyboard connected. The unit is
capable of being used in a closed arcade cabinet with no additional
keyboard or controls and motherboard booting into an emulation menu. If
an auxiliary keyboard is connected it can be used fully and even used
during gameplay alongside your control panel.
USB
NOTES: In USB mode the
keyboard
pass-thru connector does still work, and the I-PAC translates the PS/2
keyboard protocol into USB. This is primarily for using interactive programming and test
mode.
It is recommended that, with I-PAC in USB mode, you normally connect
your PS/2 or USB keyboard directly to the PC.
USB
DOS SUPPORT: Most PCs support
a
USB
keyboard in DOS mode so I-PAC in USB mode MAY work in DOS. (USB
keyboard support may have to be enabled in the BIOS). HOWEVER: many
BIOSes have poor USB support which prevent use for gaming, as the
response is too slow. USB is intended for Windows use, either in a "DOS
box" or a windows application.
USING
TWO I-PACs TOGETHER: Two
boards
can
be used for doubling the number of inputs. The second board can be
connected to the pass-thru connector of the first. Or either connect
both boards to USB or the first to the keyboard port and second to USB.
Each board can be individually programmed with the required code set,
then the two boards can be connected together as above.
WIRING TWO JOYSTICKS TO
THE
SAME CONNECTION: This
is fine, and is often done when using a dedicated 4-way joystick
alongside an 8-way. Both joysticks could be wired to the Player 1
inputs. They will both perform the same function of course.
LED
HARNESS: (Optional). The LED
harness
plugs onto the 10-way header on the board. The LEDs are connected to
the harness via a removeable plug. This can be disconnected to allow
the LEDs to be mounted through a panel. Ensure to note which way round
the plug is fitted to the LED. The LEDs can be tested by pressing caps
lock, scroll lock and num lock on a pass-thru keyboard. If you have
connected the I-PAC to the PC using USB, in mame.ini change "led_mode"
from "ps/2" to "usb"
IMPORTANT
NOTE!
The LED harness and the PCB take 5 volts from the PC motherboard.
Ensure no exposed parts of either touch to ground. If this occurs the
motherboard could be damaged. Most motherboards supply the 5 volts to
the keyboard connector via a tiny wired-in fuse which looks like a
resistor. If the 5 volts is shorted this fuse will need to be replaced
which is not easy!
Mount
the PCB on a wooden
control panel or other insulator, or
if this cannot be done, use stand-off pillars. When the LEDs are
connected to the harness a small length of pin is left exposed. This
can be bent over to secure the plug and should be insulated with tape
as one pin on each LED is connected directly to 5 volts.
Using
the 9-pin Header
The diagram below will help if you decide to make your own LED
connections. The header plug pins are shown looking from the top.
Troubleshooting
General Approach:
The on-board self-test LED gives a display of functional checks, see
later in this section for more details.
Remember that the I-PAC emulates a keyboard. So if you bear this in
mind, you can use any program that displays text to test the response
with certain limitations. Notepad or the DOS prompt can be used for
example. You can connect a short piece of wire to GND and use the other
end to touch onto various input connections, and characters should be
typed on the screen. Bear in mind, though, that the default MAME
configuration includes many non-printing keys such as ALT, CTRL and the
arrow keys, so trying the player 2 inputs is best as these are all
printable characters.
But Notepad or DOS cannot tell you whether an input is "stuck" though
so is not a complete test. For this you need to use the
I-PAC test
mode
or
Ghostkey.exe. (A
DOS
program). For Windows, the best test by far is the
Passmark
keyboard Test
which we can recommend downloading. It's a 30-day trial version but
hopefully you will have it working by then!
Problem: Player 2 buttons 5
and 6 not working.
This is not an I-PAC problem! By default, MAME does not have these
buttons assigned to any keycodes. Just go into the MAME controls menu
(press tab in a game) and assign them. Button 5 is "I" and Button 6 is
"K".
Problem:
No shift functions work.
Part of the shift function design means that to avoid "stuck" keys,
shift functions are disabled when any key is pressed. So loss of shift
functions means you have a shorted or stuck switch. Problem is, which
one? There are two ways to determine this. The on-board LED gives an
indication of which input is shorted, see later in this section.
Or use the built-in test mode:
Run any text-display program such as Notepad, or if you are in DOS type
"COPY CON" to turn off the command prompt. With a keyboard plugged into
the pass-through port, press CTRL-ALT-P (press and hold each key in
this order). You will go into programming mode. You will see a
menu. Enter "T" for test mode. The offending stuck input(s) will be
displayed on the screen.
Problem:
Cannot program. Utility hangs at end of
programming.
If you are using the PS/2 connection, and do not have any USB keyboard
on your PC, you will need to check that in the PC BIOS, "USB keyboard
support" or "Legacy USB Support" is DISABLED, otherwise WinIPAC will
not program properly.
Another cause of this is having non-switch items connected to inputs.
In general, the inputs must be "open" (ie no switch pressed) for
programming to work. This may not be the case if you have other things
connected such as a game board connected at the same time as the I-PAC.
Email for further advice on this if you must have other devices
connected as there are workarounds.
Problem:
Erratic behaviour of joystick
directions. Shift functions not working. "Stuck" keys.
A very common cause is connection of the inputs to the "NC" contact on
the switches instead of "NO". See the "no shift functions work" heading
above for more info. This type of problem usually occurs when a large
number of switches are incorrectly connected. The self-test LED will
indicate this problem.
Problem:
Slow response and stuck keys in
Windows 98 when using I-PAC in USB mode.
This is caused by the motherboard USB controller not working in
Windows. The keyboard (and therefore I-PAC) is relying on the slow BIOS
for support instead of the Windows USB controller drivers. Go into the
BIOS setup and disable USB keyboard support or "legacy port 60-64
support". If the I-PAC stops working completely then this is the
problem. Now go into device manager in Windows and check the USB
controller for any driver problem.
Problem:
In USB mode, the I-PAC was not
detected properly once before and now I can't get it out of this state.
You will need to remove it from
Windows and let it re-detect. Go into
Control Panel, System, Device Manager, Hardware. Open up the USB
controller by clicking on the plus sign next to it. Under this heading
will be displayed all the USB devices. Right click on all devices one
by one except the controller itself and Root Hubs and select
"uninstall". Now unplug and re-plug the I-PAC. It should be
re-detected.
Problem:
In USB mode, it is only detected
as "Unknown Device" or "device has a problem".
Under certain conditions,
shorted inputs can cause this, or inputs that
are held at 5 volts. This may happen either because of a wiring error
(see steps for checking this, above) or the I-PAC inputs being
connected to something other than an open-circuit switch. If you need
to connect non-switch devices please email for advice.
Problem:
Keys intermittently sticking in one
direction.
This is usually not an I-PAC
problem. If you check the I-PAC
installation using the
Passmark
Keyboard Test you
will probably find that this works fine and you may need to look
elsewhere on your PC installation such as some errant software
consuming PC resources.
Using
the Self-Test LED
The self-test LED indicates status and errors by using flash patterns.
This is the sequence of events
on power-up:
Power applied: One short flash
Then
PS/2 Interface detected: a second short flash and then if switch test
passed: LED stays lit
Or
USB Interface detected
Then
USB Interface initialized by PC and switch test passed: LED stays lit
Or
If inputs test fails: LED flashes a number of times to indicate which
switch is shorted or faulty. LED then stays off. This does not
necessarily mean the board will not work, but indicates a switch wiring
or other problem which should be investigated. Check the table below
for the failing input. Check switch wiring. Try disconnecting this wire
and see if the flash pattern changes.
Error Conditions:
LED never lights:
Board faulty, cable faulty, PC not powering up correctly.
LED
gives two short flashes and
the I-PAC is connected via
USB:
The board has mis-detected a PS/2 interface. Check USB controller is
enabled and working on the PC. Try another USB device as a test.
LED
gives one short flash then
stays off:
I-PAC has detected a USB controller but the PC is not detecting the
device as having been connected. Check USB drivers on PC.
LED
flashes 3 or more times
after initially lighting:
Switch test failed. Check chart below for failing input. Check switch
wiring. Try disconnecting this wire and see if the flash pattern
changes.
Switch test failure codes.
Count
the number of flashes after the first time the LED
lights
The table shows the input which needs to be investigated. Check for
incorrectly-wired switches. Try disconnecting this switch. The test
might now pass. If more than one input is failing, the pattern may
change, indicating a second failing input.
