Note 1 : after sending the CUMn command, the instrument remains in configuration mode.
Power cycle the instrument to activate the set operating mode.
Parameters for RS232 and RS485 ASCII proprietary modes:
Command Reply Description
CU1Ac &| Sets the address for RS485 ASCII
proprietary mode to c value
The address is an alphanumeric character
ranging within 0…9, a…z, A…Z
Default : 0
RU1A & c| Reads the address for RS485 ASCII pro-
prietary mode set in the instrument
CU1Bn &| Sets Baud Rate for RS485 ASCII
proprietary mode to:

9600 if n=3

19200 if n=4
 38400 if n=5

57600 if n=6

115200 if n=7
Default : 115200 (n=7)
RU1B & n| Reads Baud Rate setting for RS485 ASCII
proprietary mode
CU2Bn &| Sets Baud Rate for RS232 ASCII
proprietary mode to:

9600 if n=3
 19200 if n=4

38400 if n=5

57600 if n=6

115200 if n=7
Default : 115200 (n=7)
RU2B & n| Reads Baud Rate setting for RS232 ASCII
proprietary mode
CU2In &| Sets interface for ASCII mode to:
 RS232 if n=0
 RS485 if n=1

RS422 if n=2
Default : RS485 (n=1)
RU2I & n| Reads interface setting for ASCII mode
CU2Mn &| Sets parity and stop bits for ASCII mode
to:
 8N1 if n=0 [No parity, 1 stop bit]
 8N2 if n=1 [No parity, 2 stop bits]

8E1 if n=2 [Even parity, 1 stop bit]

8E2 if n=3 [Even parity, 2 stop bits]

8O1 if n=4 [Odd parity, 1 stop bit]
 8O2 if n=5 [Odd parity, 2 stop bits]
The number of data bits is fixed to 8
Default : 8N2 (n=1)
