J22 LX-Bus Expansion Connector
24.1 Description
J22 LX-Bus and J21 RS-232 connectors cannot be used at the same time. Either use J21 to connect a serial
device for PC Log Reporting, or use J22 to connect an LX-Bus device. This is determined by where you install
the jumper on J23 6-Pin Header. Reset the panel using J16 jumper to activate selected J23 operation.
Note: Do NOT use shielded wire when using the LX-Bus. Do NOT connect the wires from the 4-wire harness
to the panel terminals.

24.3 LX-Bus LEDs
The two LEDs, located near the bottom-right corner of J21 indicate data transmission and receipt. The
top LED ashes green to indicate the panel is transmitting LX-Bus data. The bottom LED ashes yellow to
indicate the panel is receiving LX-Bus data.
24.4. OVC LED
The Overcurrent LED (OVC) lights Red when the devices connected to the Keypad Bus and LX-Bus(es) draw
more current than the panel is rated for. The OVC is located above Outputs 1 and 2 on the panel and turns a
steady Red when lit. When the OVC LED lights Red, the LX-Bus(es) and keypad bus shut down.
J21 Serial Connector
25.1 Description
Note: J22 LX-Bus and J21 RS-232 connectors cannot be used at the same time. Either use J21 to connect a
serial device, or use J22 to connect an LX-Bus device. This is determined by where you install the jumper on
the J23 6-Pin Header. Reset the panel using J16 jumper to activate selected J23 operation.
To enable J21 to operate in RS-232 mode place a jumper on the two pins next to the letter “R” on the J23
6-Pin header. The Serial Connector allows the XR2500F panel to transmit PC Log Reports directly to an
RS-232 device.
25.2 Serial Connector LEDs
The two LEDs, located near the bottom-right corner of J21 indicate data transmission and receipt. The
top LED ashes green to indicate the panel is transmitting serial data. The bottom LED ashes yellow to
indicate the panel is receiving serial data.
