Chapter 3: Operation

RS-232-Interface operation

All important unit functions can be remote controlled via the RS-232-Interface (V24 standard) by a PC terminal which can be operated with commercial terminal programs (e.g. Telix, Procomm...). AS a data terminal (DDE) the VOR/ILS Analyzer EVS200 must be connected with a RS-232-1:1-Interface. Also it is possible to control the unit with an user defined program. The necessary commands for that pur- pose are described below.

COM-Parameter

The com parameters parity, number of data bits, and stop bits cannot be changed and are defined as "firmware“.

non parity bit		(N),
	8 data bits	(8),
	1 stop bit	(1).

Handshake

Hardware handshake is renounced.

Handshake is performed by software as a transmitted sequence e.g. "READY“ or as a measuring value or a tuning value e.g. "RF107000“.

Control commands

There are two categories of control commands.

super commands (mode independant, unit related)

mode dependant commands (specified mode must first be selected)

The following table makes clear the control commands structure.

	unit related		mode dependant control commands
