Product Description The TUNet 1200 is an electromechanical meter reader and Local Area Network (LAN) transceiver, designed to fit under-the-glass of single-phase electricity meters. As part of the LAN, the TUNet 1200 transmits and receives data to and from other TUNet devices within a controlled area. It then connects to the Network Controller, which is the central control point between the network and the utility.

Installing the TUNET 1200 BEFORE YOU BEGIN 1. Assemble the necessary equipment: Tantalus TUNET 1200 Module Installation Kit and required tools and materials.
CAUTION: The TUNet 1200 modules contain electrostatic sensitive devices. You must work with the modules at a protected workstation. Persons handling the modules must be grounded with a protective wrist strap. When you remove the modules from their packaging, place them on antistatic foam. When handling the modules, hold them only by the edge of the plastic holder. DRILL THE METER BASE GE I-70-S 1. Remove the glass cover from the meter and place the meter face down into a fixture for holding the meter.
3. For the octagonal shape, remove the “crosshairs” with needle nose pliers. Figure 2: ABB AB-1 Vent hole with “crosshairs”. 4. Make sure there is no debris in the meter by cleaning it with compressed air. Mark the disk 1. If the disk is not already marked, remove the meter nameplate and set the original nameplate mounting screws aside. (you will need longer screws to mount the module under the nameplate). 2.
3. Peel the red liner from the adhesive tape on the IR interface adapter. 4. Insert the IR interface cable through the drilled hole from outside to inside the meter. 5. Arrange the IR interface so that the flat side of the sensor is toward the center of the meter. The legs of the meter will guide the sensor positioning. 6. Make sure you position the sensor in place as straight as possible. The split cylindrical protrusion on the adhesive side of the sensor will fit into the 3/8" drilled hole. 7.
2. Attach the connector of the IR serial interface to the mating connector on the TUNET 1200 module. 3. Position the module over the mounting posts on the meter. 4. Position the nameplate over the module. 5. Using the appropriate ¾" mounting screws, secure the module to the mounting posts taking care not to interfere with the meter disk. The module is now ready for initial programming.
