radio links the outlying Remote site into the rest of a licensed
MAS system by sending data from that site to an associated
TransNEXT installed at one of the licensed Remote sites (see
Figure 4.)
As the data from the outlying site is received at the licensed
Remote site, it is transferred to the licensed radio (via a local
cable connection) and is then transmitted to the MAS Master
station in the usual manner.

Extending a TransNEXT Network with a Network
Repeater
Similar to a Tail-End Link, Store-and-Forward (SAF) offers a
way to physically extend the network range, but in a simple
and economical manner. SAF works by dividing a network into
a vertical hierarchy of two or more sub-networks. Extension
radios (designated as MODE X) serve as single-radio
repeaters that link adjacent sub-networks, and move data from
one sub-network to the next one.

TransNEXT Installation
Figure 6 shows a typical Remote station arrangement. Master
stations are similar, but an omni-directional antenna is normally

used instead of a directional type, and a host computer
replaces the data terminal equipment.

The following steps provide an overview of the installation
procedure.
1. Select a site that provides stable power, protection from the
weather, entrances for antenna and other cabling, and an
antenna location with an unobstructed transmission path in
the direction of the associated station(s).
2. Select and install an appropriate antenna and feedline for
your system requirements. Professional Installation is
required. Feedline losses and antenna gains must be
properly accounted for. Please refer to Table 5.1 and Table
5.2 in section "5.0 Antennas" for more details on approved
antennas and feedline requirements.
3. Mount the transceiver to a stable surface using the
brackets supplied with the radio (fasteners/anchors are not
supplied).
4. Connect the data equipment to the transceiver's DATA
connector. Use only the required pins for the application.
Refer to Figure 7.
5. Measure and install the primary power for the transceiver.
It must be within 6–36 Vdc (including transients) and be
capable of providing 12 watts over this voltage range.
(Typical current draw is 860mA @13.8 Vdc; 2.0A at 6 Vdc.)
A power connector with screw-terminals is provided with
each unit.
