Check the modem handbook to verify the correct commands. Note that these
commands are executed automatically with the RESET MODEM command.
2. Add the prefix required for access to the public telephone network to the
destination telephone number. Depending on the in-house telephone system,
a certain prefix may have to be added to the destination number in the XBS
system configuration/site definition screen prior to sending the set-up to the
remote Excel 100C controller.
Set-Up for Limited Communication Speed
The communication speed of the modem can be fixed to a lower rate in case of data
transmission errors due to telephone line limitations. See the XI581/582 Buswide
Operator Interface User Guide, EN2B-126GE51, for the procedure for fixing the
baud rate.
Troubleshooting
In case of any problems, the handbook of the modem or ISDN* terminal adapter
must be consulted.

TCP/IP DIAL-UP VIA TCP/IP MODEM XM500
The Honeywell TCP/IP modem XM500 allows use of a TCP/IP network (e.g.
Ethernet LAN/WAN networks) to achieve a dial-up connection between an XBS
building supervisor and an Excel 100C controller. The set-up is identical to that of a
telephone modem connection with the exception of the additional need for definition
of the Ethernet address.
