General

This leaflet provides general information for the Wireless WIC communication option for the
REXUniversal meter. For information on installing the REXUniversal meter, see the “REX® Meter Family
Installation Instructions” (IL42-4026H or later).

The REXUniversal meter may be ordered with a wireless cellular communication option: the Wireless
WAN Interface Card (Wireless WIC). The Wireless WIC is available in CDMA 1xRTT/1xEV-DO and UMTS/
HSPA+ versions, providing a high speed, 3G cellular communication channel for the meter. Additional
hardware configurations may include an internal service control switch and control board for standard

®

meters.

Placing the REXUniversal meter with Wireless WIC into service

Use authorized utility procedures when placing the standard REXUNIVERSAL meter into service.
Equipment damage, personal injury, or death can result if authorized utility procedures are not
followed.

See IL42-4026H or later for the REX Meter Family meter installation instructions. When planning the
meter installation, consider the following additional guidelines:

• Since the Wireless WIC and EA_LAN (if present) are high frequency communication devices, site the
meter so that the front of the meter has the best possible view of the surrounding terrain.

• Do not place metal structures (other than the meter socket and related cabling) within 20 cm of the
meter.

After the REXUniversal meter is installed and powered as instructed in IL42-4026H or later, the
installation is complete. To verify operation of the Wireless WIC on-site, the following steps may be
taken:

1 After installing and powering the REXUniversal meter, wait approximately 5 minutes for the Wireless

WIC to connect to the cellular network and initialize.

2 Using Metercat and an optical probe connection, perform a diagnostic read. Be sure the WAN

Configuration view is included in the viewset. For information on using Metercat and performing
diagnostic reads, see the Metercat software documentation or online Help.
