Security Functions - Ten-Tec RX-340 Technical Manual

5-10 RX-340 SECURITY FUNCTIONS:
The RX-340 operates in one of three control modes: Local, Remote, or Local Lockout
mode. The RX340 may be switched between Local and Remote mode by pressing the
Remote button or sending the appropriate *R or *L RS-232 interface command. In
Remote mode, the RS-232 interface has control and front panel operation is not allowed.
The user may return the RX-340 to Local mode by pressing the lit Remote button. In
Local Lockout mode, the lit Remote button will not return control to the front panel.
The RX-340 includes additional commands for interface control and secure operation.
The new commands are part of the extended command set which is a superset of the Ten-
Tec RX-331 command interface.

interface:
*R1 Remote Control ON.
