18 TMAA01-02 RS-232 Board
The TMAA01-02 RS-232 board fits inside the radio in the
options cavity and is connected to the main PCB by the internal
options connector and loom.
The RS-232 signals are then made available on the 9-way D-
range connector mounted on the RS-232 board. This connector
fits through the external options connector hole provided in the
radio chassis.
18.1 Operation
The TMAA01-02 RS-232 board provides a suitable interface to external
devices requiring full RS-232 level compatibility. As well as supporting
transmit and receive data lines, the board also supports RTS and CTS
hardware flow control lines.
18.1.1 Hardware Flow Control
Although the serial transmit and receive lines are dedicated connections on
the internal options connector, the RTS and CTS lines have to be assigned.
For hardware flow control, these lines are set up in the programming
application. RTS should be assigned to IOP_GPIO3 and CTS should be
assigned to IOP_GPIO1.
Refer to the online help of the programming application for
more information.
Important The radio does not meet the IP54 protec-
tion standard once an RS-232 board has
been installed unless the external options
cover seal is installed.
Important To comply with EN 301 489-5, all
cables connected to the external options
connector must be less than three metres
(10 feet) in length.
