 RS-232C operation.
 SCPI
AT682/683 can use the RS-232 interface to communicate with the computer to
complete all the instrument functions.
6.1 About RS-232C
You can connect a controller (i.e. PC and PLC) to the RS-232 interface using Applent
RS-232 DB-9 cable. The serial port uses the transmit (TXD), receive (RXD) and signal
ground (GND) lines of the RS-232 standard. It does not use the hardware handshaking
lines CTS and RTS.
NOTE:
JUST ONLY Use an Applent (not null modem) DB-9 cable.
Cable length should not exceed 2m.
