Contemporary Controls BACnet BASrouterLX User manual

MS/TP Physical Layer Bias and Termination
End-of-Line termination (120Ω) is normally applied at both ends of the MS/TP bus,
especially when using long cable segments and faster data rates. Fail-safe voltage
bias (200mV) ensures stable MS/TP operation. The BASrouterLX is shipped with fail-
safe voltage bias and EOL termination applied. Depending on the application, these
can be configured by removing jumpers inside of the case.
End Device – In a router application where the location of the router is at the end of
the MS/TP bus segment – both bias and EOL termination must be applied.
Middle Device – In a router application where the location of the router is anywhere
between the end MS/TP devices (in the middle of the bus), termination jumper
should be removed. Fail-safe voltage bias jumpers could be left in place depending
on whether other devices on the MS/TP bus are providing additional bias or not.
Three configuration jumpers are located inside BASrouterLX’s case near the MS/TP
connector. Removing the BASrouterLX cover provides access to the 6-pin jumper
block.
The BASrouterLX is a high-performance BACnet router providing stand-alone routing
between BACnet networks such as BACnet/IP, BACnet Ethernet, and BACnet
MS/TP. Besides its high-speed processor, it has advanced features such as MS/TP
slave proxy support (allowing auto-discovery of MS/TP slaves) and diagnostic MS/TP
frame capture and storage for use with Wireshark®. Up to 50 BBMD and 147 FDR
entries can be made. The BASrouterLX has two physical communication ports — a
10/100 Mbps BACnet/IP Ethernet port and an optically isolated EIA-485 port for
MS/TP. Router configuration is accomplished using a resident web page.

Power Connection
The BASRTLX-B requires 24 VAC or 24 VDC while drawing no more than 10 VA of
power. The recommended conductor size is 16–18 AWG. COM is directly connected
to zero volts and the chassis is DC isolated from zero volts. Input connections are
reverse-polarity protected. See figure below for power options.
WARNING: Internally, this device utilizes a half-wave rectifier and therefore can only share the same AC
power source with other half-wave rectified devices.Sharing a common DC power source is also possible.
Sharing AC power with full-wave rectified devices is NOT recommended. Devices powered from a
common AC source could be damaged if a mix of half-wave and full-wave rectified devices exists.

WebPageConfiguration
The BASrouterLX is web page configurable using recent versions of most standard web browsers. To configure the router initially, connect it to a PC using an Ethernet cable
and set the PC’s IP and subnet mask in Local Area Connection –> Properties. In the Internet Protocol Version 4 (TCP/IPv4) settings of your Windows PC, specify an IP
address and a Subnet mask in the same subnet as the BASrouter (e.g. 192.168.92.5 /24).
BASrouterLX’s factory-programmed: Default IP address is 192.168.92.68 and a Class C subnet mask of 255.255.255.0 (/24). User Name is: admin and Password is: admin
ATTENTION: The default login credentials must be changed before the BASrouterLX can be used or its system configuration altered. Please
change the username to an 8-63 character alphanumeric value (at least one letter and one number), and the password to an 8-63 character
alphanumeric and the optional special characters allowed (~!@#%^+[ ]{ }_) value. This ensures authorized access to the router only.
Reset IP switch is located on the front, underneath Power LED. Press and hold the Reset IP button using a paper clip for at least 5 seconds while
the router is powered. Remove power and restore power again to complete the reset IP, User ID, and Password procedure to factory-programmed defaults. For complete
details on BASrouterLX, please download our BASrouterLX. User Manual at: https://www.ccontrols.com/basautomation/basrouterlx.php and click on the Support tab under
