Options Extender Boards
The TMAA01-05 and TMAA01-07 options extender boards
provide external access to most of the signal lines provided by the
radio’s internal options connector.
The options extender board fits inside the radio in the options
cavity and is connected to the main PCB by the internal options
connector and loom.
The internal options connector signals are then made available
on the high-density 15-way D-range connector mounted on the
options extender board. This connector fits through the external
options connector hole provided in the radio chassis.
19.1 Changing the Options Extender Links
Note
The following instructions on links apply to the 220-65203-02
revision of the TMAA01-05 board only. For information on
boards from revision -05, refer to technical note TN-1260-AN.
The options extender board configuration must be completed before the
board is installed in the radio, as the top side of the options extender board
is not accessible once the board is screwed to the radio lid.
Important
This equipment contains devices which are susceptible to
damage from static discharges. Refer to
“ESD Precautions”
on page 112 for more information.
The options extender board has various link options which allow the user
to re-configure the outputs available on the external options connector. The
outputs that can be made available by changing linking resistors are:
■
the 5V supply line, and
■
the RX_BEEP_IN line.
In both cases, these lines replace other lines that are available when the
linking resistors are in the factory-set configuration. Note that there is no
external connection available for the RX_AUD line.
Important
The radio does not meet the IP54 protec-
tion standard once an options extender
board has been installed unless the exter-
nal options cover seal is installed.
