SRC-4 Installation and Operation Manual
INSTALLATION
Configuration Dip-switch Setup
The configuration dip-switch package (SW1) is located on front panel of the SRC-4.
Note: After changing any dip-switch, please repower the unit.

Auto-Detect
In auto-detect mode the SRC-4 can automatically detect and set itself to the baud
rate a connected serial device. This allows the SRC-4 to be used with a wide range
of serial devices.
To use the Auto-Detect feature power down the SRC-4, turn SW1-1 on, and connect
the serial device you wish to interface with. Configure the serial device to send an
uppercase U. Power up the SRC-4, from power up there is a 3 second window in
which a received U will set the SRC-4’s baud rate. Once the baud rate is detected
and set the SRC-4 will send its version information over the serial port. After SRC-
4’s baud rate has been set it will retain this setting until the auto-detect feature is
used again.
