Probes
• For RS-232C connection with a PC or PLC, connect the mini DIN plug of an optional conversion cable IF-A29 to the
RS-232C connector of the probe, and the D-sub plug to the RS-232C connector of the PC or PLC via a cross cable. The
baud rate of the probe is set to 38,400 bps.
In this case, it is also necessary to use the cable's power supply line to supply power to the probe. As a power source,
5 V/300 mA is required.
To control a probe from a PC via RS-232C, use the supplied SDK (CA-SDK2). For the specifications of the SDK and how to
use it, refer to the instruction manual for CA-SDK2.
