10.1: Hardware Overview
The Nexus® 1250/1252 meter with the INP2, Internal Modem Option, has all the
components of the standard Nexus® meter plus the capability of connecting to a PC
via a standard phone line. No additional hardware is required to establish this connec-
tion.
If desired, the internal expansion port of the Nexus® 1250/1252 meter can be config-
ured with an internal 56K bps modem. This gives the meter Dial-In and Dial-Out
capability without additional hardware. This configuration of the meter is ideal for
small remote applications.

nal Modem Option. The RJ11 connection is virtually unlimited, since it utilizes a PSTN
(Public Switched Telephone Network).
