7.9 SB-293 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 7-2, and Figure 10-1 on page 71).
• Placing a Jumper across JP12 pins 1 and 2 configures the satellite board for
general-purpose inputs and outputs.
• Removing the 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 controller board).

7.10 Installing the SB-293 Satellite Board onto the PXL-250
Controller
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 corners of the satellite and controller PCBs.
3. Line up the stand-offs in the top two corners of the satellite PCB with
corresponding mounting holes in the controller PCB (see Figure 7-3 on page 31).
4. Align the Satellite Board to Motherboard connector pins.
5. Gently press the two boards together with each stand-off into its mounting hole
and with the connector pins meshing together.
6. Turn the controller’s power ON.
7. If the J2 and P2 connectors have been meshed together properly, the LED on the
SB-293 (see Figure 10-1 on page 71) will turn green.
