MagicQ User Manual 290 Version 1.4.9.0
36.2 Connection (MagicQ Consoles and MagicQ MaxiWing)
On the MagicQ consoles the remote input is provided on a standard 4 pin mini DIN connector.
The connections are (in the sequence they appear physically on the connector)
2 0V and equipment ground
4 Opto isolated input negative
3 Opto isolated input positive
1 Power supply positive (5 Volt, current limited)
The remote input can be used to receive an external signal on the opto isolated inputs, or it can be wired to
an external switch. To receive an external signal wire the signal + to pin 3 and the signal – to pin 4. When
used as external optically isolated input the maximum continuous voltage rating is 24V DC.
When wiring to an external switch links pins 2 and 4. Then connect the external switch between pins 3
and 1.
On MagicQ consoles shipped prior to 22 November 2006 it is necessary to make a modification to the
BIOS setup on the console to enable the remote switch. Connect the keyboard to the console, then on
start-up press and hold DELETE for 10 seconds – this should reveal the BIOS setup window. Select
“Peripheral interfaces” and change parallel port to “ECP/EPP”. Then select “Save and Exit”.
