  • Page 32: Rs-232 Control Of Tx And Rx Units

    Configuration, cont’d RS-232 Control of Tx and Rx Units When the FOX 2G Tx/Rx AV is configured by RS-232 commands, some commands are processed by the transmitter and others are processed by the receiver. The SIS commands do not distinguish between the two units. The system routes the commands based on where they are processed.

  • Page 33: Introduction To Sis

    Introduction to SIS SIS commands consist of a string (one or more characters per command field). For the FOX 2G Tx/Rx AV, apart from setting audio gain ("G") and attenuation ("g"), upper and lower case characters may be used interchangeably. Commands do not require any special characters to begin or end the command string.
