controller a 3 rd etc. But, our RCP8 is customized to display 13 BITE units, which can be seen in
the screen shot1.
Screenshot 1 : Opening BITEX window
All BITE units are connected electrically to the Radar Control Processor (RCP) via
interfaces such as contact closures, analog voltages, or serial communications. For maintenance
purposes time variations of these units can be customized for display in graphical user interface.
The RCP8 integrates all of this information and sends it via multicast networking to IRIS for
ultimate display in the bitex utility. These packets are mingled with the RCP8 antenna controller
commands on the same network port.
Invoking Bitex: Bitex is invoked graphically either from irisnet, utils or from the Radar Status
Menu. However, bitex can also be invoked from the command line with the following command:
$bitex&
