Table 5-1. Description of the LEDs functionality during normal modes of
the transceiver’s operation (Continued)
LED ‘name’
Functionality
RF Rx
Turns On when the radio is starting an Rx frame. Turns Off when the
radio quits an Rx frame.
If the radio is programmed to be a Slave and if the RF link is solid, this
LED should stay On almost 100% of the time.
RF Tx
Turns On when the radio is starting a Tx frame. Turns Off when the radio
quits a Tx frame. Therefore, if radio has been programmed to have at least
one Tx frame in its FrameTable, this LED will always turn On at least for
a very short period of time even if the radio has nothing to send over the
RF channel.
The LED stays On for as long as the transceiver stays in the Tx mode.
CTS1
RS232 data port #1 flow control LED. If Off = the buffer is full or near
full. The user’s data device should stop sending the data.
CTS2
RS232 data port #2 flow control LED. If Off = the buffer is full or near
full. The user’s data device should stop sending the data.
Additionally, the LEDs indicate different stages of the transceiver’s operation while the
transceiver is in one of its special operation modes. These cases are explained in the table
below.
