Tx Control
This radio button selects the unit’s mode at the beginning of a transmission
RTS – Request to Send
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
(see Figure 18).

DCD Control

DTE Baud Rate
This field selects the port speed of the COM Port (independent of RF Network Speed)
1200

For best results, CalAmp recommends using the same rates for both the COM Port and RF Network Speeds. Always have RF
network speed equal to or greater than COM Port speed.
