G100 icon is red, and the
Status Bar reads: ’Error’. No communication between PC and G100.
Check that...
• the cable is correct (standard 0-modem cable),
• you are using the correct COM port in your PC,
the baud rate selection in the PC tool is 9600.
Access
via
modem Modem connection cannot
be established. G100 modem is not properly connected to the telephone line, or G100
modem is not in auto answer mode.
• Check that the cable between G100 and modem is correct
(standard modem cable = all pins straight through).
• To activate auto answer mode, use a terminal program (e.g. pro-
comm) to send the following AT-command: ‘ATSO=1’.
Modem connection has
been established but the
G100 icon turns red and the
Status Bar reads: 'Error'. No communication between PC and G100. This could be due to a bad
telephone line.
• Hang up and try again.
If this does not help, check that...
• the modem can work without DTR being present. Use a terminal
program (e.g. Procomm) to send the following AT-command:
‘AT&D0’.
Common to all
connections The communication be-
tween PC tool and G100
seems to be OK. Several
CU 300 units are con-
nected to G100, but none
or only some are shown in
the PC tool. No communication is taking place between G100 and the CU 300
units.
• Check that the connection between G100 GENIbus port and
GENIbus is correct (see G100 Installation and operating instruc-
tions).
• Go through the checks of bus units, GENIbus connections and
GENIbus cable as described in preceding section.
