8.5 Toggling Zoom / Pan and Mouse modes
Both the Pan feature and Mouse emulation feature can be used at the same time and you can toggle
the arrow-key usage by pressing the PAN button on the remote control. If you find the arrow-keys not
controlling the mouse pointer, simply press PAN once to de-select PAN mode. Similarly, to re-
activate PAN mode (to slide a zoomed image around the screen) press PAN again.
9. RS – 232 CONTROL
All of the functions of the Magellan MDC - MK1 can be controlled from the Computer, using the RS –
232 port on the unit. Using an appropriate cable and software, it is easy to communicate with the
Magellan MDC - MK1, but before the communications can be established, first set the computer's serial
port to:
§
8 bit data, 1 stop bit, no parity
§
Either no flow control, or hardware (RTS / CTS) flow control
§
Set the Baud rate on the computer and the Magellan MDC - MK1 to the same value (usually 9600).
Commands are sent over the RS – 232 in one of two ways:
§
Send the 'adjust name' followed by = and a number (plus a carriage return) to alter any setting you
see displayed on the lower line of the LCD display. E.g. If you were using a terminal emulator
program, you could type the following command to immediately set flicker reduction to 6 lines:-
§
Flicker Red = 6
§
Send just the 'adjust name' (plus a carriage return) to retrieve back the current value for a setting.
E.g. Typing the following returns the correct value back from the Magellan MDC - MK1 unit (e.g. '6'):-
Flicker Red
Responses to commands
The response from the Magellan MDC - MK1 can be one of three things:
§
“?” if something is not understood, e.g. an adjust name is misspelled;
§
“>” if the command has been executed;
§
“nnnnn” (i.e. a five digit number from 0 to 99999, followed by a CR and LF) if a setting value is
returned.
Notes on sending commands
§
Settings that are one of two values (e.g. NTSC or PAL) have to be sent as 0 or 1.
§
You only have to send a maximum of 4 characters in order for the command name to be recognized
- e.g. "Flicker Red = 6" could be shortened to "Flic = 6".
§
Spaces and line-feeds (ASCII code 10) are completely ignored.
§
You must
always
send a carriage-return (ASCII code 13) at the end of your command or value
request.
