Receiver Memory Command Set; Receiver Query Command Set - Ten-Tec RX-340 Technical Manual

5-5 RX-340 RECEIVER MEMORY COMMAND SET:
The command set provides two commands for accessing the receiver's 100 memories.
Memories are stored in a battery-backed RAM and will remain stored during power down
and storage. A master reset will clear all stored memories.
Wnnn WRITE MEMORY
Write current Operating Parameters to memory number 'nnn' (1-
100) available. The memory holds all basic receiver operating
parameters such as frequency, mode, filter selection, etc.
Example:
Rnnn
RECALL MEMORY
Recall memory 'nnn' to main operating Parameters. Memory
channels 1-100 available.
Example:
5-6 RX-340 RECEIVER QUERY COMMAND SET: Some commands request the
receiver to send information back to the controller. These responses generally follow the
same format as an issued command. For example, a typical response to a Current
Operating-Frequency query might be: 'F 10.12345' (or 10.123.450 MHz). In addition,
whenever the receiver sends information, a status code is appended to the end of each
response. The status code is the letter 'S', followed by a number. For example, 'S1'
indicates the receiver is operating in remote mode. The status number codes are as
follows:
1 Receiver is in remote control mode.
2 Synthesizer is out of lock.
4 Not used.
8 Last string had character transmission error.
16 Last string had data error.
32 Last string had lost data.
64 External reference applied.
A properly operating receiver and interface typically returns an 'S1' status code
terminated with a carriage return ASCII 13 (hex 0D).
'W20' (Write parameters to memory 20).
'R20' (recall memory 20).
