10.3 Data/Telemetry/SCADA/Text
For sending and receiving information (data, text) over the Serial I/O (RS232) port see
the Modes section.
For SCADA probably just need transparent data, which several of the available modes
can do:
LSUB—point to point, no addressing, broadcast, no acknowledgment of data.
TUP—broadcast data, Packet headers, and can be digipeated.
Terminal Mode—can have connected transparent link.
10.4 Digipeating
If your system needs a repeater function see the Modes section and the DIGIPEAT
command.
11 INSTALLATION
Refer all installation to qualified personnel.
11.1 Dc Power
Make a power cable assembly using the supplied two-terminal connector, P1, some wire
of sufficient size and length, and mating connection to your dc power source. It is
recommended that a fuse with a rating of 3 A be used at the dc power source end of the
power cable assembly.
A two-terminal jack, A2J6, is located on the front panel for dc power input. The unit is
protected from reverse voltage application with a diode, A2D1, and from over current
with an automatic resetting solid state current limiting device, A2RT1. Equipment power
must be supplied by a well-regulated dc power supply capable of the required voltage and
current. For vehicle applications an external filter to reduce ignition noise transients and a
method to absorb load dump conditions is recommended. After-market dc noise filters
are available from automotive electronics supply companies.
The dc power connector, A2J6, is located on the front panel to the far, left side. Pinout is
as follows. Be sure you wire to the correct terminal on the mating connector. Plug P1 in
to A2J6 to make sure.
