 Tx Control
This radio button selects the unit’s mode at the beginning of a transmission
o RTS – Request to Send
o DOX – Data Operated Transmit
The Transmit Control default mode is DOX in which the unit begins a transmission as soon as data is presented to the COM
Port. The optional mode is RTS in which the unit begins transmission only when the RS-232 RTS input pin of the COM Port is
raised and continues transmitting until the RTS is dropped. Selecting RTS also activates the switched option in DCD control.
