Command Byte: 'U'
Format:
'U3'
Activate override mode and switch in Amplifier Switch 2.
'U2'
Activate override mode and switch in other Amplifier Switch 2.
'U1'
Activate override mode and switch in Amplifier Switch 1.
'U0'
Activate override mode and switch in other Amplifier Switch 1.
'UM' Activate overide mode.
'UA' Terminate overide mode, activating automatic mode.
Notes: When sending a 'U3', 'U2', 'U1' or 'U0' command, also send a 'UM' command to the other amplifier to
prevent unwanted automatic-mode switches.
Command Byte: 'X'
Function: Configures serial communications on the specified port. Use this command carefully as it could cause
you to lose communications 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.
