SB-293 Board Installation
Jumper Settings
On the SB-293 satellite board, there is only one jumper that may require setting. JP12 configures the
satellite board for either second door control or for general purpose inputs and outputs (see Figure 2,
and Figure 4 on page 15).
JP12 – Configure Satellite Board
– Jumper across JP12 pins 1 and 2 configures the satellite board for general-purpose
inputs and outputs.
– NO Jumper across JP12 configures the satellite board for second door control with
additional inputs and outputs. When the satellite board is configured for second door
control, the primary door must be connected to the "A" reader (TB-5 on the PXL-250
controller board) and the secondary door must be connected to the "B" reader (TB-6 on
the Receiver board attached to the controller board).

Installing the SB-293 Satellite Board
Board Installation
Perform the following steps to install an SB-293 satellite board onto a PXL-250 controller.
1. Turn the controller's power off.
2. Line up the upper left-hand corner of the satellite PCB with the controller PCB.
3. Line up the stand-offs in all four corners of the satellite PCB with corresponding mounting
holes in the controller PCB (see Figure 3).
4. Gently press each stand off into its mounting hole.
