Connection Examples
The connection examples in the remainder of this section show only the basic connection diagrams. We rec-
ommend that appropriate noise countermeasures be taken in actual applications, including the use of shielded
twisted-pair cables. Refer to Recommended RS-422A/485 Wiring Examples on page 767 for actual wiring
methods.
Host Computer Connections
1:1 Connections Using RS-232C Ports
• IBM PC/AT or Compatible Computers
• Using NT-AL001 Converting Link Adapters
Note
We recommend using the following NT-AL001 Link Adapter Connecting Cables to connect to NT-AL001
Link Adapters.
XW2Z-070T-1: 0.7 m
XW2Z-200T-1: 2 m
!Caution
Do not use the 5 V power from pin 6 of the RS-232C Option Board for anything but the NT-AL001
