Advanced Global Technology QSP-660 Manual De Usuario

      

The QSP-660 has a built in RS-232 serial interface that supports remote control of the QSP-660 through simple
ASCII commands. These commands provide access to the front panel button operations just as the IR Remote
Control does.

The QSP-660 serial interface is fixed at 2400 baud, 8 bits, 1 stop bit, and no parity. It uses the very simple
command format:

<command> <return>

The command is 2 character or 2 character plus parameter and must be followed by a carriage return. The
QSP-660 will respond with:

>

if the command was recognized, or

?

if the command was not recognized or is invalid

The following commands are supported by the QSP-660 serial interface and behave just as if the indicated front
panel button was pushed:

BD

Display button

BS

Sequence button - will cause QSP-660 to start or stop sequencing during live mode.

BP

PIP button

BQ

Quadrant button

BV

VCR button - will cause the QSP-660 to enter or exit VCR playback mode

BF

Freeze button - will cause the QSP-660 to freeze during live mode

BB

VCR button - will cause the QSP-660 to enter the VCR bypass mode

BC n

Camera buttons - is a number 1 through 4 corresponding to the camera number. A space or tab
must be entered between the command and the number.

BZ

Zoom button – will expand a quadrant of any image in playback. Repeated entries of this
command will rotate through the quadrants.

Commands only take a fraction of a second to execute within the QSP-660. However, there must be a
delay of at least 0.3 seconds (300 milliseconds) between the carriage return and start of the next
command. The command decode prompt (

>

) may occur before the command has finished executing and

should not be used as an indication to send the next command.

For proper RS-232 operation, the 8 position DIP switch, SW 5, located next to the DB-9 RS-232 interface
connector within the QSP-660 must be set to the factory default positions as indicated below. The DB-9
connector pinout corresponds to a standard 9-pin DCE (modem) device.
