technical bulletin
XJ Scroll One-Way Communication Board Configuration
XJ Scroll address is determined using dip switches on the One-Way Communication Board.
Switch numbers 1 to 6 set the slave address. Switch number 7 will set the Baud rate and switch
number 8 will set the parity. The range of allowable addresses is 1 through 63. Refer to Table 2
for settings.
Make sure that you are setting the same parity and baud rate as that in E2.
Please note the Termination JP3 Jumper is just used for the devices at beginning or end of the
chain – any devices in the middle of the chain do not need it.
JP3 Termination Jumper ON = Add 150 Ohm resistor between A and B
JP3 Termination Jumper Off = Remove 150 Ohm resistor between A and B
