Connecting to the Host’s RS-232C Port Section 5-1
Usable Cables with Attached Connectors:
• For host link, 1:1 NT Link, or 1:N NT Link (+5 V power supplied from PLC)
XW2Z-070T-1(9-pin to 9-pin, 0.7 m)
XW2Z-200T-1(9-pin to 9-pin, 2 m)
CVM1/CV-series CPU Units whose model names do not have the suffix -EV@
cannot be connected by any connection method.
When connecting to the peripheral port of a CS/CJ-series CPU Unit, a CS1W-
CN118 Connecting Cable is required in addition to the above cables. (Supply
power to the +5-V output of the NT-AL001 from an external power supply
when using this method.)
• When using the host link or NT Link (1:1) method, short the RS and CS
terminals at the PLC side with each other (leave the RS and CS terminals
at the NT-AL001 side open).
• When using the NT Link (1:N), cross-connect the RS and CS terminals at
the NT-AL001 and PLC sides.
If there is +5 V output at the PLC side, no external power supply is re-
quired for the NT-AL001.
