Command Format 
The receiver uses a standard format for all configuration commands. 
1.  A single command letter. Lower case letters allow the current parameter 
state to be viewed without modification. Upper case letters allow the user 
to change the parameter configuration. 
2.  One or more parameter characters. Parameter characters are only used 
when modifying parameters. They have no effect when parameters are 
viewed (lower case command letters). 
The following is a list of command letters and their meanings: 
V – Firmware version ID. Takes no parameters. 
S – System ID. Used to configure the receiver to only accept signals from 
ProScale displays that have the same system ID programmed. 
Prevents other displays on other systems within radio range from 
being received. The default is 0. 
O – Output mode. Formats the record text for the desired data content. 
See Output Modes on page 9 for more information. The default is 
mode 3; position, units and display ID. 
D – Configures the delimiting character that is used to separate fields 
within a record. The default is a space. 
E – Enables or disables the character echo when typing in data from the 
terminal program. The default is ON. 
M – Record Start Marker. Enables or disables the use of the new record 
start (sentinel) character, which is an *. When enabled, each new 
record received starts with an asterisk (*). The default is OFF. 
T – Record Terminator. Each record can be terminated with either a 
carriage return or carriage return and line feed. The default is CR/LF. 
B – Baud Rate. Sets the baud rate used to communicate with the 
receiver.  The default is 9600 bits per second.
