INSTRUCTIONS FOR USE
OM 652UC
The instruments communicate via serial line RS232 or RS485. For communication they use the ASCII protocol. Communica-
tion runs in the following format:
ASCII:
8 bit, no parity, one stop bit
The transfer rate is adjustable in the instrument menu and depends on the control processor used. The instrument address is
set in the instrument menu in the range of 0 ÷ 31. The manufacture setting always presets the ASCII protocol, rate of 9600
Baud, address 00. The type of line used - RS232 / RS485 - is determined by an exchangeable card automatically identified
by the instrument.
COMMANDS FOR INSTRUMENT OPERATION
The commands are described in specification you can find at
