1-6 Computer control
Connect the AR-ONE to the serial port of a computer using an RS-232C serial cable
terminated in a 9-pin male connector. The RS-232C parameters may be defined using the
CONFIG
menu. Baud rates (transfer speed) set to either 4800 or 9600 bps. Since there are
two independent RS-232C port with the AR-ONE, it is possible to set an ‘address’ to
facilitate connection of up to 99 AR-ONE to a single PC.
The RS-232C parameters are as follows:
Baud Rate: 4800 or 9600 bps
De-limiter: CR, LF
Data bit: 8 bit
Stop bit: 2 bit
Parity: None
X parameter: ON
1-7 IF output and Spectrum Display Unit (SDU5500, SDU5600 )
The rear panel has a 10.7 MHz IF output designed to drive the optional SDU5500 or
SDU5600 Spectrum Display Unit. The SDU5500 or SDU5600 provides an excellent tool for
locating elusive transmission with a PEAK capability to ‘freeze’ the briefest of transmissions
for later measurement of frequency and level after the event.
(Note: The IF output frequency is selectable in the
CONFIG
menu. (10.7 MHz or 455KHz).
