Repeater function
The implemented Pacific Crest/TRIMTALK modes support also the repeater function. The repeater
function is configured either by using the SL commands:
•
”SL@M=R” (Repeater ON)
•
”SL@M=O” (Repeater OFF)
or by selecting Repeater OFF/ON in the Additional setup-> Repeater programming menu.
Note 1. The repeater modem passes TRIMTALK messages also to its serial port unlike for example
Pacific Crest PDL modems.
Note 2. If error correction is ON (FEC ON) and TRIMTALK mode is activated by using ”SL@S=3”
command, the firmware automatically switches SATEL FEC OFF temporarily, and turns it back at
the mode return.
7.9.6
Support for Local / Remote addresses
If the modem has TX address ON then primary TX address is handled in the same way as Remote
address in Pacific Crest PDL modems. The default value is 0x00FF (255 in decimal format) i.e. the
broadcast address.
If the modem has RX address ON then primary RX address is handled in the same way as PDL
Local address in Pacific Crest PDL modems. The default value is 0x0000 (0 in decimal format).
SATELLINE modem needs to have TX Delay 50ms or more in order to avoid messages from
colliding in case it is to be placed in a Pacific Crest system that uses addressing and
acknowledging scheme.
Note 1. SATELLINE-modems do not support Pacific Crest retransmit/acknowledge scheme.
However, that has no effect in RTK applications because they utilize only broadcast
messages.
7.9.7
Latency
In the PCC Transparent protocol mode (Option 1 and Option 2) the whole message is first read
from the serial port and after that it will be framed and transmitted over the radio.
The end of the message is detected when there is a pause in data coming from the serial port.
The symbol rates for the Pacific Crest 4FSK (Option1) are:
•
19200 bps on 25 kHz channel
•
9600 bps on 12.5 kHz channel
