6.1.8 Computer Remote Control
V4400QS-1 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 3, RS-232 Commands.
Signal Format is as follows:
1. Data Format: 1,200 Baud/8 Data Bit/No Parity/One Stop Bit.
2. Mode: Half Duplex Mode (Not Echo Received Character).
