Potential conflicts:
- Pacific Crest Local/Remote addresses are supported in the firmware versions starting from
v3. 46.3
- Repeater function is supported only in the firmware versions starting from v3. 46.3
- Error check and Full CRC16 check must be OFF in SATELLINE modem
- FCS (Free Channel Scanning) feature is not supported by Pacific Crest radios
- Message Routing is not supported by Pacific Crest radios
- SATELLINE RX/TX addressing does not use ARQ scheme like Pacific Crest radios.
5.7.5 Repeater function
The implemented Pacific Crest/TRIMTALK modes support also the repeater function. The
repeater function is configured either by using the SL commands:
o ”SL@M=R” (Repeater ON)
o ”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.
5.7.6 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.
In case only broadcast messages are used (like in RTK applications) there is usually no need for
TX Delay, except if the transfer delays identical to Pacific Crest modems are preferred – in such
cases an appropriate value of TX Delay is 34 ms.
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.
