Configuring the CPU Board

Most of the boards in the control system have one or more jumpers that can be set to configure the board for various special purposes. The default configuration will be used in most cases. Refer to the SRS Hardware Reference manuals for more details on each board and the various jumper options.

Here are the default jumper settings for the CPU and RCB boards.

Basic Checklist

Make sure all CPU board jumpers in properly set.

The CPU board executes the main control system functions including routing the audio, controlling the transmitter PTT lines, command decoding, and command response telemetry generation. The CPU board also provides a serial RS-232 connection to a PC for controller configuration, and 24 user defined I/O connections including digital inputs, analog inputs and buffered digital outputs.

CPU Jumper Settings

JU1 - DVB Jumper

The DVB jumper enables or disables audio from the DVB_bus signal on the backplane. This signal is audio generated from the optional Digital Voice Board or DVB.

"DIS” In normal operation when not using the DVB, the jumper MUST be in the disabled or "DIS" position.

"EN": When using the optional DVB in the system, JU1 MUST be in the enabled or "EN" position.

JU2 - Digital Pot Bypass Jumper

OUT: Default. Set telemetry level under CPU control. This is the normal state for this jumper.

IN: Force telemetry pot to mid scale. This overrides the CPU level set for the master telemetry generator.

JU3 - ICD Power

OUT: Default. For using Con 3, the 10 pin header connector for in-circuit progamming.

IN: Install if using Con 5, the modular ICD jack for in-circuit programming.

NOTE: When using the ICD jack, you MUST cut the trace on the bottom of board to enable the ICD power.
