computer to complete all the instrument functions.
10.1 AboutRS232C
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.
