Stand-by level can either be: LOW = 0 volt or HIGH = 5 volt.

Go to SimNet diagnostic interface - step back with [GAIN-]

CRC checksum error counter - if the figure is not 0 it could be due

to a number of things and not necessarily that there is a system error.

However, if the counter is active and the number is rapidly increas-

ing, then the system has detected a fault.

For instance, if the SimNet cable is pulled, the counter will be acti-

vated and once the cable is back in place, the counter will stop, but

will stay at the figure it has reached. So therefore, a figure other than

0 does not necessarily mean that something is wrong, only if the

figure continues to increase.

Prior to call for technical assistance:

1. Check connected cabling.

2. Check supply voltage to be between 11.8-15 VDC to the SimNet

system.

3. Systematically disconnect one unit at a time to see which one is

causing the problem. Start at the opposite end of the 12V power

supply.

The two last lines in the SimNet diagnostic interface are for techni-

cians only.

Go to the next interface - step back with [GAIN-]

The interfaces: SimNet input, SimNet output, NMEA0183 input and

NMEA0183 output are for technicians only.
