WARNING
CONNECT ONLY TO A GROUNDED 50/60 HZ AC OUTLET PROVIDING THE
CORRECT VOLTAGE (115 VAC OR 230 VAC, AS DELIVERED).
DO NOT REMOVE OR DEFEAT THE GROUNDING PIN ON THE AC POWER CORD.
A SERIOUS SHOCK HAZARD MAY RESULT FROM FAILING TO
MAKE CONNECTION TO A PROPERLY GROUNDED ELECTRICAL OUTLET.
DO NOT USE THE CHASSIS SIGNAL GROUND THUMBSCREW AS A
SAFETY GROUND POINT.
DO NOT USE THIS PRODUCT OUT OF DOORS, IN RAIN, OR
IN DAMP OR WET ENVIRONMENTS.
Each DigiCart/E is factory configured for only 115VAC or 230VAC operation. Please check the marking
on the rear panel to see if you have the correct DigiCart for your power supply. Use the AC service cord
provided to connect the unit to utility power. Use only Underwriters Laboratories recognized replacement
cords.
Chassis Ground Screw
A thumbscrew is provided to reduce longitudinal grounding errors between devices having interconnected
low-level signals. This feature may reduce hum on the analog input ports.
C ONTROL S IGNALS
Several of the most useful standards have been selected to interface DigiCart/E with professional
audio-video equipment and allow functionality with automation systems for the development of
custom applications. Detailed technical information about the interfaces will be found in the
Appendices.
Remote Control
A Remote Control port is included on the rear panel for connecting DigiCart/E with a 360 Systems
RC-320 desktop remote control.
The control port provides bi-directional serial communication and power. This port is dedicated to an
RC-320 remote. Since an RC-320 remote can control more than one DigiCart, a Remote Bus
connector is also supplied on DigiCart/E to daisy-chain remote commands to several DigiCarts. The
Remote Bus can be connected to a mix of DigiCart IIs and DigiCart/Es. The pinout used on the
Remote Control port can be found in Appendix A, Interface Wiring. Specifics of supported protocols
can be found in Appendix B, Serial Control Protocols.
Remote Bus
The Remote Bus connector on DigiCart/E is used to daisy-chain remote commands to several
DigiCarts. The Remote Bus can be connected to a mix of DigiCart IIs and DigiCart/Es. Automation
systems can also control DigiCarts through this port. (The Remote Bus connector should not be used
as an input when an RC-320 is connected to the Remote Control port)
