Pin assignment of the 422/485 interface
Pin assignment of the 422/485 interface is given below.
SDA: Differential output (+)
SDB: Differential output (-)
RDA: Differential input (+)
RDB: Differential input (-)
TRM: Termination resistance
S. G. : Signal ground
*Applicable plug: XW4B-06C1-H1 (by OMRON)
Note:
-
On the unit located farthest from the host, such as a PC or a sequencer, short-
circuit the TRM and RDB terminals and wire the internal termination resistance.
-
The end of each cable should be stripped 7 mm.
-
The terminal block terminal screw tightening torque is 0.6 N·m.
-
The wiring cables should be AWG 28 to AWG 16.
-
Use twisted pair cables
-
The optional parts mounting section is insulated from the internal circuit by a
optocoupler.
-
The common of optional BCD output and RS-232C interface is connected.
-
Connect the cable to the CSD-918 power supply terminal block F.G. terminal to
ensure CSD-918 conforms to CE and JIS standards.
