SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE
RGB Termination - Input impedance
This relates to whether or not the Magellan MDC - MK1 is terminating the computer monitor output from
the computer with 75-Ohm impedance.
§
Usually the MDC - MK1 will set the termination automatically ('Auto' mode), by sensing whether a
computer monitor is linked into the circuit as well (i.e. to the “Local Monitor” connector).
§
However, if necessary, it is possible to turn the termination off. For example if the MDC - MK1 does
not sense that the monitor is attached, this could result in ‘double-termination’ of the RGB signals.
§
Press the - button to turn the termination off, the + button to switch to automatic mode.
RS-232 Port – Control Via RS – 232 / Mouse Emulation
This switches the use of the RS – 232 serial port between computer control and Microsoft ® serial mouse
emulation
§
In order to use the remote control to emulate a mouse, this RS – 232 adjustment must be set to
'Mouse' mode. Similarly, to use a serial link from the computer to control the MDC - MK1, it must be
set to RS – 232 Control mode.
§
Note that the default is 'Control' mode - you must switch to 'Mouse' mode in order to enable the
mouse emulation.
§
Press the - button to switch to Mouse mode, and the + button to switch to RS – 232 Control mode.
Baud Rate - for RS – 232 Control
In order to control the Magellan MDC - MK1 from the computer it is necessary to set the same baud rate
for both the unit and the controlling computer.
§
Press the + and - buttons to change to the required number. The Magellan MDC - MK1 does not
display the actual baud rate, but a number relating to it. The table in a later section on 'RS232
Control' shows which Baud rate each number relates to. For example: to set to 9600 Baud the number
must be 23.
§
"9600, N, 8, 1" is the default setting - i.e. no parity is used, 8 data bits are required, and 1 stop bit.
§
This number is only used in RS – 232 Control Mode.
§
Mouse Mode ignores this number, and always uses 1200 baud.
RS – 232 ID
This ID code can be used where multiple Magellan MDC - MK1's are all linked via a serial cable to the
same computer. The ID can be altered so that each unit's ID is unique, and thus each unit could be
adjustable by itself with one serial port. This feature is described further in a later section.
Sound – on / off
The internal sounder is used to give an indication of whether a variable has been changed, or if the MDC
- MK1 is saving settings to non-volatile memory. If you do not wish any audible indications to be present,
the sounder can be switched off.
