Table 4. Configuration jumpers
Jumper Function
JP1 Address jumper „1”
JP2 Address jumper „2”
JP3 Address jumper „4”
JP4 Address jumper „8”
JP5 No function
JP6 Disabling communication failure signalling (compatibility with XM-8-BRD)
JP7 Selection of operating mode: standalone/network
FDM Firmware download mode
Note: Every time a jumper is put or removed it is necessary to restart the module in order to make
new settings effective. The restart can be done by means of RESET button or power supply switch
off and on.
The address of XM-8DR can be programmed by means of jumpers based on their values e.g.
jumpers on pins JP1 and JP3 signify the address ID=5 (1+4 = 5) while jumpers on all JP1…JP4 pins
signify ID=15 (1+2+4+8 = 15).
Jumper JP6 is used for ensuring compatibility with previous versions of XM-8 module and it is
necessary to put jumper JP6 if XM-8DR is to operate with PRxx2 series controller (RACS 4).
JP7 pins can be used for selection of operation mode. If the jumper is on JP7 then XM-8DR
operates in standalone mode and then its relay outputs can be activated by electric signal at
corresponding inputs i.e. IN1 -> REL1 and IN2 -> REL2. If there is no jumper on JP7 pins then XM-
8DR operates in normal mode and control of its outputs and inputs is performed by controller by
means of RACS Clock & Data protocol.
Note: In case of network operating mode i.e. communication with PR series controller, it is
necessary to set XM-8DR address in range ID=8...11.
3.2 Access control in elevators
All versions of XM-8 expander can be used in elevator access control. In the figure below there is
shown typical connection diagram of PRxx2 series controller, XM-8DR module and elevator control
panel.
