Introduction
1.1 Purpose and Use
The Transceiver 3A (
FCC ID: MLLGL3RPT450
) is a receiver/repeater that is used for data
transfer in Miltel’s radio telemetry system. The system is used for utility
consumption readings collection system as well as for other applications such as in
agricultural systems or general purpose sensor telemetry system. This device is
installed on-site by a professional field technician, thus this manual includes
technical terms. The equipment should not be installed by a non-professional
individual that has not been trained and authorized.
1.2 System General Description
The Transceiver 3A system is a computerized fully automatic radio device. It
requires no human intervention after initial installation. The device acts as a store-
and-forward radio relay. The Transceiver 3A operates as a Gateway (backhaul
receiver) or as a repeater that captures transmissions from a Miltel transmitter and,
after validating the message, transmits the message again. When operating as a
Repeater the device relays information from transmitters to a receiver that acts as a
Gateway (base station) which is typically deployed with a RS232 connection to a PC
or with a LAN connection (TCP/IP) that allows backhauling data to the backoffice
management system. The Gateway (Receiver) transfers the data to the central
computer for data collection and for further analysis and reporting.

When operating as a Gateway Receiver, the device receives messages transmitted
by Miltel transmitters or messages relayed by a repeater. The receiver can also send
commands to any of the repeaters.
The Transceiver device is marketed as two models (as a Receiver or as a Repeater)
and under three different commercial trade names (Datasense Repeater 3A /
Receiver 2A, Galaxy Repeater 3A / Receiver 3A and IrriWise Repeater 3A / Receiver
2A).
The Transceiver device (both receiver and repeater) can be hooked up to a PC or to
a laptop computer for programming purposes during system setup.
1.3 Theory of Operation
The Transceiver 3A is the intermediate link in the wireless telemetry data collection
system. It is an independent unit that operates as a repeater (radio relay) or as a
gateway backhaul device (receiver).
Figure 2-1 (see below) depicts a typical installation of a Transceiver 3A unit. The
device is powered by a 12 volt power supply or by a solar powered battery.
The Transceiver 3A operates its radio receiver on a continuous basis until it receives
a message from a nearby transmitter. After capturing the transmitted data
message, it sends out an identical message which is forwarded to the Collector.

Installation Instructions
3.1 General
The Transceiver 3A should only be installed by a professional technician.
3.2 Installation
For on-site installation of the Transceiver 3A device, proceed as follows:
1) Loosen the four screws fastening the unit's panel and open the box end cover.
2) Connect the 12 volt DC power supply (use only U/L approved power supply) to
the 5-pin connector
3) Close case
4) Install screws and mount to wall or to mast
5) Connect the Coax cables at both ends – to the repeater/receiver and to the antenna
3.3 Antennas
The Transceiver 3A is supplied with one of the following antenna models and should be
installed only with one of these models that are supplied with the device. Installing the
equipment with any other antenna other than those listed below may violate FCC regulations
and is therefore prohibited.
• Mars Antenna - Model M216
• Phantom Antenna - Model OEM2326-110

1) The equipment user is required by the radio service rules to obtain a license before
operating the equipment. Licensing of this equipment is the user’s responsibility,
and licensability depends on the user’s classification and application, and on the
selected frequency. The user is strongly urged to contact the appropriate
telecommunications authority concerning proper licensing, and before choosing
and ordering frequencies.
2) The equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential

energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
3) Warning: Changes or modifications to this equipment not expressly
approved by Miltel Communications Ltd. could void the user’s authority to
