EXCEL 500/600 INSTALLATION INSTRUCTIONS

Modem or ISDN Terminal Adapter Connections

For remote communications, a modem or ISDN terminal
adapter can be connected directly to the serial port of the
Excel 500-XCL5010 Controller.
The serial port of the Excel 500-XCL5010 controller accepts a
standard modem cable with a female 9-pin connector. Use
the cable that is supplied with the modem/ISDN terminal
adapter.
The communication speed is 9600 baud by default but can be
set as high as 38.4 Kbaud.
For more details, see section "Remote Communications" on
page 43.

Changing Between MMI and Modem Connection

The Excel 500-XCL5010 will detect when an MMI or
modem/ISDN terminal adapter is connected and will adjust
XI582
the communication speed automatically according to the
preset values. This automatic detection can take up to 5
seconds.
