Appendix B – USB Power Interface and Contact Closure Script Start
Besides Power Over Ethernet, the LSS-100P can also be powered by a 5VDC power supply driving a
mini-USB connector. A standard USB to min-USB cable can be used. As an alternative, USL can
supply 10m (30 ft) long cable, adapter board, and USB power supply to drive the LSS-100P. These
can be used to power the LSS-100P and use contact closures to start scripts.
Note orientation of adapter in USB power supply (terminals down).
1. If USB power or contact closure script triggering is being used, connect the supplied cable to the
LSS-100P. Connect the other end of the cable to the USB adapter board. Refer to Figures 23 and
24 for wiring instructions. If contact closure script triggering is being used with Power Over
Ethernet, the USB cable can be routed directly to the GPIO connections on the server. Refer to
figure 4 for wire colors.
2. If contact closure script triggering is to be used, connect the contact closures from the digital
cinema server to the USB adapter board as shown in Figure 25. Pulses should be about 500ms
long.

a) Define a cue at the start of the Show Playlist to pulse (500ms) a contact closure between
terminals A and ground on the USB adapter board. This contact closure or the Ethernet
command causes the LSS-100P to start executing script 0 (the first script).
