Figure 2-6. Setting the TRL-35 as a Transmitter in PDL Protocol
• Protocol
Select PDL w/EOT.
•
Channel
The current Transmit/Receive frequency channel in
MHz
.
• Modulation
The modulation for PDL protocol is GMSK.
• Forward Error Correction (FEC)
Enable to maximize data communication. With this
parameter enabled, the rover radio modem has the
capability to check and correct transmission errors (if
any) in an incoming data stream
. For PDL protocol, FEC
must have a check mark.
• Scrambling
Enable to provide more robust data communication over
high interference areas
. For PDL protocol, Scrambling
must have a check mark.
• Mode
The Radio Operation mode. To set the TRL-35 into transmit
mode, choose Transmitter as the Mode. In PDL protocol, the
TRL-35 currently supports operation as a Transmitter and
