Amplifier Communication and Protocol, Rabbit CPU
Set Serial Configuration
Command Byte:
‘X’
Function:
Configures serial communications on the specified port. Use this
command carefully as it could cause you to loose communication with the
amplifier. See the
Get Serial Configuration
query for a related command. To
configure the serial port, use Parameter Format 1. To configure RS-485, use
Parameter Format 2.
Parameter Format 1:
“CBBBBBBPDS”
C Communications port to configure 1=COM1, 2=COM2.
BBBBBB Desired baud rate:
057600, 038400, 019200, 009600, 004800, 002400, 001200
P Parity, “n”, ‘O’, or ‘E’.
D Data bits, ‘8’ or ‘7’.
S Stop bits, ‘1’.
Parameter Format 2:
“RABC”
Response:
“ABC”
A ‘4’ or ‘2’ Wire
B ‘T’ (Terminated) or ‘U’ (unterminated)
C RS 485 address
Notes:
1. The parameters listed represent all options currently available.
2. The leading zero on the baud rate is there to facilitate selection of higher
baud rates in future software revisions.
3. Amplifiers currently support just two data/stop configurations: 8/1 and 7/2.
Thus byte “S” is a placeholder.
Compatibility:
Not available when talking to an amplifier via a Digital
Outdoor Controller.
