Modem or ISDN* Terminal Adapter Connections
The front serial port of the Excel 100C accepts a standard modem cable with a
female 9-pin connector. Use the cable that is supplied with the modem/ISDN*
terminal adapter.
To connect to the rear terminals on the base of the Excel 100C, use cable XW571
(length: 6 ft (1.9 m)).

Make sure the port selector switch is set appropriately. Failure to do so can
cause erratic system operation (see page 30 for details).

Modem Requirements
•
Modem must support Hayes-compatible command set (not V150 or V151 =
Microsoft command set)
•
Modem must support alpha-numeric return codes
•
Modem must follow serial baud rate of the controller
•
Modem must support auto-bauding (baud rate fall-back)
•
When carrier detect (connect) is reported, the carrier must be on simultaneously
at both modems (on controller side and on XBS side)
⇒
use same modem
•
After a switch-on of the DTR line by the controller or XBS, the modem must
accept a dial command after 3 seconds
•
Modem must answer AT commands in less than 3 seconds
No Set-Up for Standard Modem Behavior
If no special modem behavior is required, there is no need to set up or initialize the
modem/ISDN* terminal adapter. The Excel 100C will automatically detect the device
(MMI or modem) attached to the serial port and set the appropriate communication
speed. The controller will also automatically adapt to alphanumeric return codes
used by the modem. This automatic detection and adjustment can take up to 5
seconds.
