Use rough metric type M2.6 x 0.45p threads to hold the cable’s set
(fastening) screws in place.
•
When creating a cable, please be aware of the following:
<For RS-422 Connectors>
• The following pairs of pin no.s must be connected (shorted).
...#18 (CSB) <-> #19 (ERB)
...#21 (CSA) <-> #22 (ERA)
• Connecting the #9 (TRMX) and #10 (RDA) wires, adds a termination resis-

Use a 4-wire cable when the PLC type is Memory Link and the cable is RS-
422.
<For RS-232C Connectors>
• Do not connect #9 (TRMX), #10 (RDA), #11 (SDA), #15 (SDB), #16 (RDB),
#18 (CSB), #19 (ERB), #21 (CSA), and #22 (ERA).
• The #1 (FG) terminal should only be connected if it is required by the de-
vice being connected to.
