The errNetTout counter, the low byte of register 4127, counts network
timeout errors. These errors occur when the network is dead. If a timeout
occurs, the scanner enters the claim token state.
The errHsa counter, the high byte of register 4127, increments when a station
higher than the set high station address is heard. If the scanner is going
online, it increments the counter and stays offline.
The errStn counter, the low byte of register 4128, increments when a
duplicate station is detected. If this error occurs when the scanner is going
online, the scanner increments the errStn counter and stays offline.
The errPasTok counter, the high byte of register 4128, increments when the
scanner is unable to pass the token. This is usually caused by bad wiring
(usually shorted) or other hardware problems. The scanner tries to pass the
token, fails to hear its own token pass message, and puts itself offline.
The errLasBad counter, the low byte of register 4129, increments when the
active station list on the ASPC2 LAN controller is invalid because of multiple
network errors. This error is caused by bad wiring or hardware.
The locations errInternal, the high byte of register 4129, and errArg, the low
byte of register 4130, are reserved. If a fatal error occurs, the values in these
registers may indicate the source of the problem. Record them for technical
support. However, the scanner uses these locations for other purposes. If
there is a value in one of these locations, it doesn’t necessarily indicate that a
fatal error has occurred.
The scanner also copies errArg to the low byte of register 4012.
