Operating Procedures
6–7
Wait for the Master to come back ONLINE. If it is ONLINE, and all the
other workstations are ONLINE, a then check the cables for this workstation.
Replace the workstation if no cabling problem can be located. If all other
workstations are ONLINE, and the one unit remains OFFLINE, and the
cables do not seem to be at fault, the problem could be with the network port.
To avoid losing data which may be in the unit, perform the following steps:
1) remove the workstation from the network, 2) connect it to an individual
power source and configure it as a Master, 3) establish communications with
it through its communications port, and 4) dump its contents via the Host
communications. Run the network diagnostics (test D and E) on the
workstation to verify that the problem is the network port.
nn–nn READY
OFFLINE [M]
The Master has not been able
to communicate with the Host
The Host has turned off this Master workstation by sending it an XOFF. The
workstation will not resume transmitting until it receives an XON. There will
be no DSR or poll for at least 10 seconds. If this condition persists, and the
Master is ready to receive data, one way to clear this condition is to enter
then exit the menu mode (ENTER/IN, the EXIT). If the condition persists,
check the cabling. After that, check the Host’s communication (both
hardware and software).
mm–nn READY
OFFLINE [C]
The Concentrator cannot
contact its Submaster
Check the cabling to the Submaster. If the cabling is correct, then verify that
both the Concentrator and the Submaster are set to the same baud rate. If the
problem persists, replace first the Concentrator then the Submaster to
identify the failed workstation.
nn READY
OFFLINE [SM]
The submaster cannot
contact its Concentrator
Use the same solution as described above.
00 READY
TERMINAL
This workstation has been reset
to factory defaults
If this was not specifically caused by changing the workstation’s station
number, then there may be something wrong with this workstation.
Reconfigure the workstation and let it continue to operate in service. If the
workstation resets again, remove it from use and send it back for service.
