SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE
§
The Magellan MDC - MK1's response should at most be within 40 ms of the receipt of the carriage-
return character. However, of course delays due to slow baud rates will play a greater part than this.
§
The Magellan MDC - MK1's input buffer is limited to 32 bytes, so do not send any more characters
(including CR, LF, etc.) than this.
§
For more information on controlling the different functions see the relevant sections earlier in this
manual.
Restricting RS232 commands to certain units
If you have a number of units all connected to the same PCs serial port (i.e. running in parallel), then you
can use the RS232 ID feature to restrict certain commands to go to only certain Magellan MDC - MK1
units. The following points outline this method:
§
Make each 'RS232 ID' setting unique to each Magellan MDC - MK1, unless you want two or more
units to respond to the same commands, in which case make them the same ID value. The default
value is 0.
§
Send the command 'ID Restrict nnn' where nnn is the number of the Magellan MDC - MK1 unit you
wish to control (from 0 to 255).
§
Follow this with whatever commands you wish to send. Units where 'RS232 ID' is not identical to the
'ID Restrict' value will not respond to or acknowledge these commands.
§
To disable this feature, you have to make the RS232 ID the same on all units (recommended value
0), and of course set 'ID Restrict' to this value.
Changing Baud Rates
Details on how to change the Baud rate are in the Advanced Features section of this manual, but the
relationship between number and baud rate is given in the table below.
Any odd number up to 191 can be selected, but only certain Baud rates are generally used. The most
common ones are outlined in the table below. For numbers not included in the table, the baud rate
associated with those numbers can be found by using the following equation:
Baud =
230400
1
Therefore, if the number displayed on the Magellan MDC - MK1 is 23 then
Baud =
230400
=
9600
23 + 1
