Simrad MS50 – Chapter 5. Appendices C-11
Ter_rate, i.e. data rate to use on terrestrial modem:
1200 bps
2400 bps
4800 bps
Default 9600 bps
14400 bps
Example:
AT +WRATE =2400,2400 ç
sets both the satellite rate and the terrestrial modem rate
to 2400 bps.
AT +WRTL =
[<low>] [,<high>]
ç sets the lower
and upper threshold level in bytes of the buffer used in the
Net service provider-to-Simrad MS50 direction (Simrad
MS50 receive buffer).
AT +WRTL ? ç
displays selected threshold levels.
AT WRTL =? ç
displays available threshold levels.
The low parameter specifies the lower threshold at which
point the Simrad MS50 ASD should issue an RR (Re-
ceiver Ready) packet signalling that it is ready to receive
data from Net service provider:
Valid value: 0-511
Default value: 120
The high parameter specifies the upper threshold at
which point the Simrad MS50 ASD should issue an RNR
(Receiver Not Ready) packet signalling that it is not ready
to receive any more data from Net service provider:
Valid value: 1-512
Default value: 240
Note! The high value must be larger than the low value.
When the high value is omitted, it becomes low value +
120.
