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 599 for actual wiring
methods.
Host Computer Connections
1:1 Connections Using RS-232C Ports
• IBM PC/AT or Compatible Computers
• Using NT-AL001-E Converting Link Adapters
Note
We recommend using the following NT-AL001-E Link Adapter Connecting Cables to connect to NT-
AL001-E 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-E Link Adapter. Using this power supply for any other external device may damage the
RS-232C Option Board or the external device.
