Nexus Monitor with Internal Modem Option

10.1: Hardware Overview

The Nexus 1250/1252 Monitor with the INP2, Internal Modem Option, has all the components of the standard Nexus Monitor PLUS the cabability of connecting to a PC via standard phone line. No additional hardware is required to establish a virtually unlimited connection from a PC to a Nexus 1250/1252 with INP2, Internal Modem Option.

If desired, the internal expansion port of the Nexus 1250/1252 can be configured with an internal 56K bps modem. This gives Nexus Dial-In and Dial-Out capability without additional hardware. This is ideal for small remote applications.

When the device is configured with INP2 , Port 2 becomes a gateway allowing other Modbus-based serial devices access to the phone line. Additional connections can include a daisy chain of standard Nexus Monitors. A Daisy Chain can include up to 31 meters. If more are desired, the installation of a repeater allows additional meters. (See section 5.14 for repeater details.)
