There are two banks of DIP switches located on the bottom of the
Note: Switch positions “1” and “0” are indicated on the bottom of the unit.
3.1.1. SetUp Switch Bank 1
The bank of switches locat d cl s st to the rear panel are used to select the Prefix Code Repetition Value, Broadcast Mode, and baud rate.
3.1.1.1.Prefix Code Repetition Value (Sw1 - Sw4)
The Prefix Code informs the unit that the next character will be a command. In order to allow the unit to adapt to a variety of applications, it is often useful to require that the Prefix Code be repeated several times in order to be recognized. For example if the Prefix Code is ^V and the Repetition Value is 4, then the sequence “^V^V^V^V” would be sent prior to a port selection command.
Note: When tran mitting binary data, it is recommended that the Repetition Value be set at four or eight. This will decrease the possibility of random characters in data being misinterpr ted as commands.
