7.1 Computer Remote Control
The V5900MUX uses a very simple command set, each command consisting of three characters. The first
character in all cases is the slash or virgule(/). The unit looks only for a three-character command, with an initial
slash. It ignores all other characters. If a mistake is made in entering a command, just type in another slash
character followed by the appropriate character for the desired command. The commands are listed in the Table
2, RS-232 Commands.
Signal Format is as follows:
1. Data Format: 1,200 Baud (Selectable)/8 Data Bit/No Parity/One Stop Bit.
2. Mode: Half Duplex Mode (Not Echo Received Character).
