10.5 Board-Only Supplemental Data

The TransNET 900 board-only radio is electrically and operationally similar
to the standard (metal enclosed) version described in the body of this manual.
Refer to this manual for connector assignments, software commands and
other product information. This supplementary data explains the items that
are unique to the board-only radio.

Product Differences—Board-only vs. Standard
The main differences between the board-only unit and the standard version
are physical—including overall dimensions and mounting hole spacing. In
addition, the board-only unit's LED panel is positioned differently than on the
standard unit. The LED order and functionality remain the same, however.
Finally, the board-only unit is not intended for high duty cycle applications
such as may be required in some master station and repeater arrangements
(see note below). This is due to heat dissipation requirements.
NOTE
The board-only unit is not suitable for extremely high duty cycle applications. For
master station or repeater use, where transmit duty cycles could approach 50%,
it is recommended that a standard (metal enclosed) TransNET be utilized.

Unit Dimensions

The TransNET board-only radio is designed to fit into restricted spaces, and
is considerably smaller than the metal enclosed version. The dimensions of
the unit (excluding connectors) are as follows:
Height: 0.906 in. (2.3 cm)
Width: 5.063 in. (12.9 cm)
Depth: 3.563 in. (9.1 cm)
The bottom of the board-only radio is not insulated. When
:
CAUTION
mounting the unit, ensure that no protruding objects will con-
tact the bottom of the circuit board.
