Troubleshooting
Communication
RS232(x) communication doesn’t work
Solution:
a) Setpoint
RS232(x) mode
is set to different setting than DIRECT
– change its setting to
DIRECT.
b) Converter to RS485 is active at this communication channel
– change setpoint
RS485(x)conv.
to DISABLED position.
c) Earthing problem exists between the PC and the controller, i.e. the battery negative potential
has different levels in the two devices. IG/IS/IM-NT controllers has a built-in protection which
disconnects battery negative (GND) from the RS232 terminal. Re-activation takes some time
(~ 1 min) after you disconnect the cable (component cools down).
You can temporarily disconnect your laptop PC from the grid (e.g. if you intend to download
controller configuration only). You can disconnect the earth wire from your PC. The best
solution is to use the RS232 galvanic separation device, e.g. one of those which are
mentioned in the InteliCommunication Guide, section Converters.
RS232(2) / RS485(2) / USB communication doesn’t work
Solution:
Relates to IG-NTC/EEC versions of IG-NT family and to IS-NT / IS-NT-BB. Controller FW
version is lower than 2.0 and/or controller was shipped from ComAp before September 2006.
It is necessary to download new FW into the communication sub-processor. It can be done by
sending unit to ComAp or by downloading the latest version of Peripheral modules upgrade
package and following procedure described in the attached documet.
Problem accessing controller after configuration programming error
Problem:
It can happen that remote configuration programming attempt fails (e.g. due to bad phone line
condition) and from that moment on controller shows on its
display “CONTROLLER
CONF
IGURATION ERROR”.
Solution:
In this stage, even with damaged configuration, controller is still able to receive another phone
call with another attempt to program configuration.
However, if the situation is to be solved locally (i.e. a local technician intends to re-program the
configuration), it is possible to switch the RS232(1) port back to the DIRECT connection mode
by simultaneous pressing up+left+right arrows on the controller.
It is strongly recommended not to upgrade controller firmware using a remote connection,
because in case of programming failure problem has to be solved locally using boot jumper
programming procedure. See
Unsuccessful controller programming
chapter for information
about this procedure.
Modem TC35i does not respond to SMS commands
Solution:
Do the following:
1. Send
AT+CPMS="MT","MT","MT"
command via hyperterminal or using the
RS232()MdmIni parameter.
2. Send
AT+CPMS="SM","SM","SM"
command via hyperterminal or using the
RS232()MdmIni parameter.
3. Restart the modem.
