(2) The terminating resistant setting shown above is an example for the NT631/NT631C. The setting
method varies with the PT. Refer to the manual for you PT for details.
Connections for Serial Gateway and No-protocol Communications
This section describes the connections for Serial Gateway, and no-protocol communications. Up to 32 nodes
can be used for 1:N connections.
Note
(1) 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.
(2) The combined cable length for RS-422A/485 is 500 m including branch lines.
(3) The maximum cable length is limited to 2 m when an NT-AL001-E Link Adapter is connected.
(4) Branch lines must be a maximum of 10 m long.
