MIB / RS232
Symptoms Cause of Failure Failure Isolation and Remedy
AGM connected to an
RS232 port not
functioning
The MIB/RS232 port is not
configured for AGM
Check configuration of the MIB/
RS232 ports in configuration
mode
The cable between AGM and
monitor is not connected correctly
or defective
Check cable connection, replace
cable if necessary
The MIB/RS232 board is in a
wrong slot (slot has been changed
after software configuration or an
additional board has been plugged
in)
Verify correct placement of the I/
O boards
The MIB/RS232 board is defective
Check board and replace if
necessary
External device not
receiving data
The MIB/RS232 port is not
configured for data export
Check configuration of the MIB/
RS232 ports in configuration
mode
The wrong data export protocol
driver is configured in the monitor
Check the export protocol
required by the attached device
and configure the monitor
accordingly
The cable between the external
device and the monitor is not
connected correctly or defective
Check cable and replace if
necessary
The external device does not support
the version of the data export
protocol used in the monitor
Check if the device supports the
version of the data export
protocol. Upgrade device or
monitor if necessary (if matching
versions exist).
A terminal concentrator is used in
between the device and the monitor
and a protocol with dynamic speed
negotiation is used
Some terminal concentrators do
not support changing the
transmission speed (baud rate)
dynamically. Check if the
connection works without the
concentrator
The MIB/RS232 board is in a
wrong slot (slot has been changed
after software configuration or an
additional board has been plugged
in)
Verify correct placement of the I/
O boards
The MIB/RS232 board is defective

necessary
