MTU150W General Description MTU150W is a long-range, synthesized radio-metering transmitter in the VHF 450-
470 MHz frequency range. When the MTU150W detects pulse conditions at one or more of its inputs the pulse is counted and saved. When the number of the pulse is equal to the Trans Scale defined by the GUP10, it is then transmitted to the central station according to the WAT-NETTM protocol selected for the system in operation. MTU150W has one connector (see Figure 1). 1. J9: The 10-pin programming jack is a serial port to connect a PC or a FTU (see Figure 1). Unit parameters and meters values are easily programmed using Gup10 utility-programming software. (See the MTU150W Programming Guide) or by the FTU. 2. Meter Input: The meter input is a two wires cable. These wires connect to the meter output. J9
Meter Input Cables Figure 1: MTU150W View Preparing for Operation Before installing the MTU150W on site, perform the following preparations:
1. Setting communication parameters 2. Self test Setting Communication Parameters
Connect GUP10 program to the MTU150W (see the MTU150W programming guide) Self-Test In order to perform a self-test please see the Field Programmer User Guide. Installing the MTU150W There are two mounting methods:
1. Wall mounting 2. On-Pipe mounting On-Pipe Mounting Installation 1. Fasten the mounting bracket on the pipe with two screws and the Omega bracket
(See figure 3) 2. Slide the MTU150W unit on the mounting bracket until the 4 clips are locking the unit 3. Define the parameters with the field programmer
(FTU100) see the FTU User Guide Insert the terminator to J9
(See figure 1) 5. Put the cover 4. Wall Mounting Installation 1. Fasten the mounting bracket on the wall with four screws (See figure 2) 2. Slide the MTU150W unit on the mounting bracket until the 4 clips are locking the unit 3. Define the parameters with the field programmer (FTU100) see the FTU User Guide Insert the terminator to J9 (See figure 1) 4. 5. Put the cover Figure : Wall Mounting Figure : On-Pipe Mounting Restrictions:
1. Do not mount the unit on any kind of metal surface. 2. Do not mount any input cable next to the antenna (see figure). Meter types:
1. There are two main types of meters:
2. Meters that produces a Passive Pulse. 3. Meters that produces an Active-
Pulse (known also as-Pulse Generator). Technical Specifications:

(230 gr.) Wiring:
1. Connect the two polls of the Meter input cable to the meter using a self-stripping insulated connector (like 3M-Scotchlock or equivalent). 2. Polarity: if a Passive Pulse type meter is connected, there is no polarity so the wires can be connected in any order, if an Active Pulse type meter is connected, there is a polarity and the wires have to be connected in the following order: Red wire to the POSITIVE (+) poll and the Black wire to the NEGATIVE (-) poll,
(see figure 4). The manufacturer is not responsible for any Radio or TV interference caused by unauthorized modifications to this equipment. Such modifications could void the users authority to operate the equipment. Figure 4: Wiring To maintain compliance with FCCs RF exposure guidelines, this equipment should be installed and operated with minimum distance 20 cm. between the radiator and your body. Use only the supplied antenna.
