Hardware Installation
Installing the CB Series module is easy. Before inserting the module into the PC/104-Plus slot,
you must first configure the I/O base address, interrupt vector, IRQ, and serial interface (for select
models).
ATTENTION
Safety First!
To prevent damage to your system or board, make sure your embedded PC’s power is turned off
before installing your CB Series module.
Step 1: Shut off power to your embedded PC and to any peripheral devices. After shutting off
power, remove the cover of your embedded PC.
Step 2: Use the DIP switches on the module to select the serial interface. Details for each model
are provided later in this chapter.
Step 3: Insert the module firmly into the embedded PC’s PC/104-Plus slot.
Step 4: Screw the control board in place.
Step 5: Connect the cables.
Step 6: Power on the embedded PC. The BIOS will automatically set the IRQ and I/O address
Step 7: Proceed with the software installation. Please refer to Chapter 3.

Rotary Switch
A rotary switch on the board makes it easy to set the appropriate signals, particularly when
installing multiple PC/104-Plus modules in the same unit. The rotary switch, which looks like a
clock, provides a bi-directional path with no signal propagation delay. The first module on the
stack should be set to CLK0, the second to CLK1, etc., to eliminate clock skew between modules.
Termination Resistor
Onboard termination resistors can be activated individually for each serial port using jumpers JP1
through JP4. JP1 corresponds to serial port 1. Short the jumper pins to activate the termination
resistor; leave the jumper pins open to bypass the termination resistor.
