6 Problem solving

Trouble shooting may be performed by using the card edge or remote status panel
displays. In addition audio monitoring of input and output busses is provided from both
the card edge headphone socket and the multi-way socket on the RM04 rear connector.

Card edge status LEDs

Board edge LEDs provide status reporting and may be useful when fault finding.

The following table summarises the card edge LED functions and colours:

Power rail

Led Colour

Description

+3V

Green

+3 volt power supply rail OK

+5V

Green

+5 volt power supply rail OK

Card edge error messages

If option cards are fitted incorrectly, the following error messages will appear

Code

Meaning

wrong ip L

Left sub-pcb (input type) is incorrect

wrong op R

Right sub-pcb (output type) is incorrect

no ip pcb

No input sub-pcb fitted

no op pcb

No output sub-pcb fitted

PCBs swap!

Input and output pcbs have been swapped L<->R

AIP not B

AIP2 card is the wrong format

Switches?

More than one menu switch in the DOWN position

No DC-DC

No dc-dc converter fitted (when analogue i/o)
