EXCEL 500/600 INSTALLATION INSTRUCTIONS 
Automatic Baudrate Synchronization 
The default communication speed between the 
XC5010C/XCL5010 CPU and the local modem/ISDN terminal 
adapter is 9600 baud. 
The communication speed between the XC5010C/XCL5010 
CPU and XBS modems/ISDN terminal adapters is auto­
matically synchronized by the two devices to the highest 
speed that both of the devices are capable of. This feature is 
called autobauding and is a feature that all state-of-the-art 
modems/ISDN terminal adapters provide when left in their 
factory default settings. 
The communication speed between the XBS and its 
modem/ISDN terminal adapter is part of the modem set-up at 
the XBS. 
Auto / Manual Answer Detection 
The XC5010C/XCL5010 CPU will automatically detect 
whether the modem/ISDN terminal adapter is initialized in 
auto-answer or manu-answer mode, and it will set the modem 
to manual answer mode (S0 = 0). 
Resetting the Modem 
For those cases where it is not clear if the modem to be used 
is in its factory setting, the modem can be reset to its factory 
setting by using the RESET MODEM command in the Start­
up sequence or through the HW Config. part of the System 
Info. sequence on the MMI. This will allow a quick and easy 
modem reset without the need to run the modem set-up 
software or the Windows™ terminal program. 
The RESET MODEM command causes the following 
commands to be sent to the modem: 
1.  ATZ  
executes hardware reset on modem  
2.  AT&FX3&W 
resets modem to factory configuration settings, 
configures the modem not to wait for the public phone 
system dial tone, and writes this to nonvolatile memory. 
Set-up for Special Modem Behavior 
If special modem/ISDN terminal adapter behavior is required, 
the communication device should be set up according to the 
instructions provided with it. This typically involves running a 
setup program on a computer with the device connected to 
the computer serial port or using the Windows™ terminal 
program. 
Set-up for In-house Telephone Systems 
A common case of special modem behavior is when the 
modem is connected to an in-house telephone network 
requiring a prefix to be dialed before the destination number 
to provide access to the public telephone network. There are 
two important aspects of the special initialization of the 
modem to consider: 
1.   Do not wait for the public network dial tone. Typically 
the init command ATX3 will trigger the modem to dial 
without waiting for a public network dial tone. Save this 
modem set-up in the modem EEPROM with the 
command AT&W. 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 500 
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 tele­
phone 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 500 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.

GSM Communication (Europe, only) 
For communication via the Global System for Mobile 
communications (GSM), a Siemens M20 Terminal (cellular 
engine) is required and must be connected directly to the 
serial port of the Excel 500 controller. The M20T translates 
the Excel CPU data received in transparent mode into the 
GSM standard. The M20T behaves like a Hayes-compatible
