USB-C Power Delivery
The USB-C port provides up to 45 watts of power to connected source. For sources that
require greater than 45 watts of power, it is able to keep the source active, but cannot
charge it. If the source is already connected to an external power supply, the UCS 303 does
not send power to the source.
Power profile:
The unit supplies all identified output voltages of 5 VDC, 9 VDC, 15 VDC, and 20 VDC per
the USB Power Delivery Specifications.
RS-232 Signal Insertion
To control a display connected to the rear panel Display RS-232 port, the UCS 303 allows
insertion of RS-232 control signals onto the cable that connects the display to the port.
Commands can then be sent via contact closure to control the display (for example, turn the
volume up and down).
PCS provides controls to set the serial port parameters and the insertion port starting point.
After the display is connected, set up RS-232 insertion as described in the UCS 303 Help
File, provided with PCS program.
The control signals can be inserted in the following ways:
•
•
4k/60 video + USB 2.0 only — mode 2
If the system requires just video and USB 2.0 (no USB 3.x data), then 4k @ 60 Hz can
be supported on the USB-C input by configuring it to operate in a mode so that all
four high speed lanes for DisplayPort Alt Mode support HBR2 (5.4 Gbps x 4 lanes =
21.6 Gbps).
Ethernet to RS‑232 insertion (see
page) — A control signal conveying commands from a control device such as an
IPCP 250 is applied to the UCS 303 LAN port, then routed to the Display RS-232
port. The RS-232 commands are inserted onto the cable connecting the Display
RS-232 port to a display. The RS-232 port can support up to a 115,200 baud rate (the
default is 9600 baud).
Captive screw insertion (see
— SIS commands are entered via PCS (see the UCS 303 Help File) and sent to the
UCS 303 LAN port. The commands are then inserted onto the cable connected to the
Display RS-232 port and applied to the connected display.
