Note 1. The following cables are available for this connection.
It is recommended that one of these cables be used to connect the RS-
232C port on the Serial Communications Board or Unit to the NT-AL001-E
RS-232C/RS-422 Link Adapter. The recommended wiring for these cables
is shown below.
2. The XW2Z-070T-1 and XW2Z-200T-1 Connecting Cables for the NT-
AL001-E Link Adapter uses special wiring for the DTS and RTS signals.
Do not use these signals with other devices; they may be damaged.
