Connections to Serial Communications Option Boards
Appendix F
NT-AL001-E Link Adapter Settings
The NT-AL001-E Link Adapter has a DIP switch for setting RS-422A/485 communications conditions. When
connecting the Serial Communications Option Board, refer to the DIP switch settings shown in the following
table.
Note
When connecting to a CP-series CPU Unit, turn OFF pin 5 and turn ON pin 6.
Connections for Host Link Communications
Port connections for Host Link communications are shown in the following table. Up to 32 nodes can be con-
nected for 1:N connections.
Note
(1) Four-wire connections must be used for RS-422A/485 connections with Host Link communications.
(2) “Resistance ON” indicates the terminating resistance must be turned ON.
(3) “5-V power” indicates that a 5-V power supply is required for the Link Adapter. Refer to the Link
Adapter manual for details. A 5-V power supply is not required for a Link Adapter connected to an
RS-232C Option Board mounted on the CPU Unit because power is supplied from pin 6 of the con-
nector.
(4) The maximum cable length for RS-232C is 15 m. The RS-232C standard, however, does not cover
baud rates above 19.2 Kbps. Refer to the manual for the device being connected to confirm support.
