XM500
TCP/IP Modem
GENERAL
The XM500 allows for communication between standard
EXCEL 5000 controllers and the Excel Building Supervisor
Central, or any controller on the Light Commercial Building
System (LCBS) and LONSTATION™, via standard Ethernet-
TCP/IP based LAN/WAN networks.
The XM500 is easy to install and to configure. Typically, with
all necessary network information being available, it can be
made operational within minutes.
The XM500 converts the serial data received from the
controller or workstation central into TCP/IP packets and vice
versa.
On its serial port, the XM500 behaves like a standard Hayes
compatible modem: It is addressed with Hayes commands,
and instead of a telephone number, IP addresses are used.
The XM500 is designed to replace the analog modem used in
our Excel 5000 and LCBS systems and provide the same
functionality using TCP/IP communications.
The XM500 may be easily configured with the IP Connect
software provided or manually via Windows Terminal
Program. The LAN/WAN network server requires no software
download for the XM500.
FEATURES
• Communication between XBS or LONSTATION™
centrals and EXCEL 5000 controllers via standard
Ethernet-TCP/IP LAN/WAN.
• TCP/IP provides more reliable and faster
communications than analog modem.
• Compatible with all HVAC systems connecting through
an SLTA-10.
• Compatible to EXCEL 5000 controllers with integrated
modem communication (O.S. version 2.01.00 or later).
• Compatible to EXCEL 5000 modem devices XM100A,
XDM506.
• Compatible to all XBS or LONSTATION™ centrals with
dial-up functionality via COM-port.
• Completely self-contained device.
• Quick and easy installation and set-up.
LIMITATIONS
The Echelon MIPS protocol requires all outbound commands/
queries be answered within 1000 milliseconds (1 sec). If any
part of the Wide Area Network is comprised of a satellite link,
it is likely to have a “propagation delay” of more than one
second, thus eliminating the use of a WAN modem. Before
installation, the user should perform tests to obtain the
response time of the network. (See “Configuration” on
page 3.)

CONFIGURATION
Ethernet LAN/WAN Information Needed
It is mandatory to get the following information from the
person that is responsible for supervising and maintaining the
LAN/WAN Ethernet system in the locations where the XM500
shall be operated:
Test Network Response Time
The network administrator should run a “trace route” between
the LAN and remote location to ensure the cumulative
response time is not near or over 1000 milliseconds.
Otherwise, the user can encounter connectivity issues.
Locations must have LAN/WAN connection
A (10bT) TCP/IP LAN/WAN connection must be available in
every location, where an EXCEL controller or a workstation
shall be operated via the XM500.
Every TCP/IP Modem needs an official IP address
This IP address must be official and permanent. It will serve
as the telephone number for the workstation or EXCEL
controller that is connected to it.
EXAMPLE: 160.221.71.130
NOTES:
1. If communication is only done internally in the
LAN, unofficial IP addresses will be sufficient.
2. If only dynamic IP addresses are available: Use a
DHCP server and have it allocate the identical IP
address every time it does a dynamic IP address
allocation.
3. For an intermediate test, the IP address of a PC
can be borrowed, but the PC must be switched off
during this test.
4. If an XM500 is connected to a LAN network which
itself is connected to WAN by using one official IP
address only via Proxy server or dynamic NAT,
this controller cannot be addressed from the
WAN.
5. Every controller that has to be accessed by the
TCP/IP modem needs its own IP address.
6. If the connection between two LANs itself is done
via dial-up, fixed IP addresses in the TCP/IP
Modem will not work. Contact your local system
administrator for help in this case.
Every TCP/IP Modem needs a network mask

TECHNICAL INSTALLATION AND SET-UP (OPTIONAL)
For ease of use, it is recommended to use the IP-Connect
Software provided to configure the XM500 controller.
However, if desired the XM500 may be configured manually.
The following sections provide the technical details to
configure the XM500 using Windows Terminal program.
IMPORTANT
For LONSTATION™ and LONSPEC™, refer to the
LONSTATION™ and LONSPEC™ Configuration
section on page 5.
Data Line Monitor
For every modem start-up, using a data line monitor is highly
recommended in order to allow checking the communication
and the RS-232 line status during commissioning.
RS-232 Breakout Box
As the XM500 does not provide LED indication of the line
status of TxD, RxD and other control, using a standard
RS-232 breakout box can be helpful.
Setting Up the XM500
1. Start a terminal program and set it up for 9.600 bps.
2. Enter <ATEV1><ENTER> and verify that the XM500
returns <OK>.
3. Enter the commands listed below in order to initialize
the XM500 for the TCP/IP communication between XBS
or LONSTATION™ and EXCEL 5000/15 controllers:
a. lockmem off : (unlocks nonvolatile memory).
b. stty xxxxx : (sets RS-232 Baud Rate to xxxxx bps;
default is 9600 bps; supported baud rates:
2.400/4.800/9.600/19.200/38.400)
IMPORTANT
If baud rates 19.200 and 38.400 bps are to be used
the autobauding MUST be switched <on> after the
TCP/IP initialization has been completed.
c. ifconfig 160.221.71.130 255.255.252.0
This example is for an IP address 160.221.71.130
with appropriate network mask 255.255.252.0.
(note the blank space between IP address and
network mask).
d. route add net default 160.221.68.1 1
(Example of a gateway definition)
Please check with the local network administrator if
a gateway definition is necessary. The parameters
are the default gateway address (160.221.68.1) and
the number of hops to the gateway(1). They must be
separated by a space
e. lockmem on : (locks nonvolatile memory).
f. autobaud on : (enables the XM500 to adapt its serial
baud rate to that of the controller or the workstation
central. This is only needed if baud rates 19.200 and
38.400 bps are to be used for XL50.)
IMPORTANT
• Above user commands can only be recognized by
the XM500 when the autobaud is <off>.
• This means that the autobaud <on> command
MUST be used AFTER the user commands have
been entered.
• If user commands should be changed, then FIRST
autobaud must be set to <off>.
4. Enter the following AT commands in order to initialize
the XM500 for the required serial behavior.

This test is to verify that both XM500s are fully initialized and
are connected to the LAN/WAN:
1. Connect a PC to each of the two XM500s that shall
communicate, and start a terminal program on both
PCs. PC terminal baud rate MUST be set to that which
the attached XM500 was programmed.
2. <ping> the IP address of the XM500 to which the other
PC is connected.
3. If the ping-test was successful, you can set-up and test
a transparent communication by proceeding as follows:
a. Action at Sending PC:<ATD 160.221.71.131>
