14.1 Description
The XR500 Series Command Processor™ panel supports RS-232, LX-Bus, and DMP Wireless operation. Only one
operation can function at a time. Install a jumper on one pair of J23 headers to indicate how the panel is
programmed to operate. Refer to the table below when installing a jumper on J23. When a jumper is installed or
movedonthe6-pinheader,brieyresetthepanelusingtheJ16jumpertoactivatetheselectedoperation.
Note: Only one operation, RS-232, LX-Bus, or DMP Wireless can function at a time.

Each Interface card LX-Bus circuit provides 100 expansion zones. The maximum number of LX-Bus zones available
on a fully populated panel is 500. Use LX-Bus J22 Header for 100 zones. Install a single Interface Card Connector

Note: Only one connector, J21 or J22 can function at a time. Either use J21 to connect a serial device for PC Log
Reporting, or use J22 to connect an LX-Bus or DMP Wireless device. Operation is determined by where you install
the jumper on the J23 6-Pin header.

J22 as a wireless bus, connect a DMP Model 300 4-wire Harness to the J22 4-pin header labeled LX. Connect the
other end to the J3 header on the 1100X Wireless Receiver. This provides up to 500 wireless zones numbered 500 to
999.Refertothe1100XWirelessReceiverInstallGuide(LT-0708).

LX-Bus zones numbered 500-599. No LX-Bus Interface Card is required.
Note: Do NOT use shielded wire when using the J22 LX-Bus Header.
The maximum distance for any one bus circuit (length of wire) is 2,500 feet regardless of the wire gauge. This
distance can be in the form of one long wire run or multiple branches with all wiring totaling no more than 2,500
feet. As wire distance from the panel increases, DC voltage on the wire decreases. Maximum number of LX-Bus
