Ipac4 troubleshooting
« on: October 16, 2010, 01:06:32 am »
I recently got an Ipac4.  I spent all day wiring it up, and when I plugged it in...nothing.  I don't even get a 'device not recognized', however the LED is constantly on.  So I assume the connection is correct.  I even tried on another computer.  Same thing, absolutely nothing happens.  And no buttons work.
I have tried on Win 7 and Vista.  Any advise is appreciated.  I can't wait to get this thing going :)

Did the ipac give you flash codes before the led went on continuously?

Troubleshooting using the I-PAC 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.
LED lights as soon as power is applied, never flashes but just stays on constantly:
See the first line of the table below

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.

See Ultimarc site for codes  http://www.ultimarc.com/ipac2.html

Also give codes for IPAC4
