Connector Pinouts . . . continued
NOTES:
• All switch inputs are active low (ie. connect to 0V to trigger). Inputs are pulled up internally to +4V via a 3K9
resistor. Inputs are also diode clamped to 0V and +4V to protect the input circuitry.
• All tallies are open collector pull-down using a 47R series resistor.
• Red Light tally contacts are via DIL relay. Contact rating is 100Vdc, 125Vac, 100mA max.
Do not use the output contacts to directly switch capacitive or reactive loads; always use an external relay with a suitable
contact rating.
PINOUTS NOT SHOWN:
• Serial ports 1 and 2 are for specific SSL equipment and their pinouts are therefore not included.
• The VGA connector follows the standard VGA pinout.
