The post-transmit interval is in progress. The transmitter
enters this state after its RF output is turned off either by a
Reset command or by the normal completion of a data
message transmission. The radio needs to wait 30 seconds
before making another transmission to keep it from going
into Failsafe mode.
On continuously.
TX326 is in the Failsafe mode. To clear a Failsafe mode, push
the Reset button (

clear the Failsafe mode.
7.3 Ports and connectors
The RS-232 port is a DB9 female connector configured as DCE. Only three pins are used, transmit
on pin two, receive on pin three, and ground on pin five. Transmit is an output and receive is an
input to the TX326. The RS-232 port allows the transmitter to be connected to a data logger
RS-232 port.
The RF Out connector is for attaching the transmission antenna. A properly matched antenna
cable and antenna must be connected to the TX326 before transmission occurs.
