  NOTES

• HCP is disabled by default.

• If the UCS is set as a DHCP client and cannot locate a DHCP server, the port is set to a link-local address.

• All Ethernet interfaces on the UCS 303 support up to 10/100/1000 Mbps (Gigabit Ethernet).

• To wire the LAN connector (see Figure 2):

• Use a straight-through cable for connection to a switch, hub, or router.

• Use a crossover cable or a straight-through cable for connection directly to a PC.

• H: Contact/Tally ports — (Optional) Wire a push-button switch or other contact closure device to pin C (contact) and pin G (ground) of the 2-pole connectors (see the image below right). These ports are configured via PCS or SIS commands.

• To make input selections via contact closure, short the C pin of each port momentarily to the ground pin (G, see 4 in the image below, right). Input switching occurs immediately on contact, and not on the release.

• Alternatively, wire a Show Me (SM) cable to the C and T pins.

• The contact closure ports have the following functions:

• Ports 1-3 — (1) These can be configured as a mutually exclusive input group to allow for input switching via SM cables. The selected input tally illuminates steadily when displayed, or blinks when muted.

• Optionally, successive contact closures of the current input can be configured to toggle A/V mute or output sync mute.

• If None is selected, contact events broadcast unsolicited SIS responses for action via the external control system. Tally ports are configured via an external control system.

• Ports 4 and 5 — (See 2 in the Contact Closure image on the previous page) These contact ports can be configured as follows via PCS:

• None — Contact events broadcast unsolicited SIS responses for action via an external control system. Tally ports are configured via the external control system.

• Single switch — Individual contact input triggers user-defined events (such as Volume Up), along with an optional repeat rate for press and hold actions (such as ramping volume up several steps). The Tally illuminates when the contact port is closed.

• Toggle switch — Individual contact input toggles between two sets of user-defined events (such as mute and unmute). The Tally illuminates when the contact port is closed.

• Group switch — Pairs two contact inputs to act as a mutually exclusive pair, which triggers events such as system on vs. system off. The Tally on the last activated contact remains illuminated.

• +V connector — (3) The +V pin constantly outputs +5 VDC power with 200 mA total (shared between pins). Use this pin when power is needed for external Tally LEDs, such as those on the Extron CCB 30 contact closure remote.

• See the UCS 303 User Guide, available at www.extron.com, for instructions on using contact closure.

• I: USB-C input — Connect a USB-C source device, such as a laptop or PC, to this USB-C connector.

• This port provides up to 60 watts of power to the connected source. If the source requires more than 60 watts, this port keeps the device functioning but does not charge it. If the source is connected to an external power supply, the UCS 303 does not send power to it.

• J: DisplayPort input — Connect a DisplayPort source device to this DP connector. The port supports up to 4k @ 60 Hz, 8-bit color with 4:4:4 chroma sampling.

• K: HDMI input — Connect an HDMI (or DVI with appropriate adapters) video input source to this female HDMI port for HDMI video with embedded audio.

NOTE: LockIt cable lacing brackets secure the HDMI cables to the ports to reduce stress on the HDMI connectors and prevent signal loss due to loose cable connections (see “Installing LockIt HDMI Cable Lacing Brackets” for installation instructions).

Installing LockIt HDMI Cable Lacing Brackets

Use the included LockIt lacing brackets to securely fasten the HDMI cables to the UCS 303 HDMI connectors as follows.

1. Plug the HDMI cable into the rear panel connection.

2. Loosen the HDMI connection mounting screw from the panel enough to allow the LockIt lacing bracket to be placed over it. The screw does not have to be removed.

3. Place the LockIt lacing bracket on the screw and against the HDMI connector, then tighten the screw to secure the bracket.
   ATTENTION

   • Do not overtighten the HDMI connector mounting screw. The shield it fastens to is very thin and can easily be stripped.
   • Ne serrez pas trop la vis de montage du connecteur HDMI.

4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing bracket as shown.

5. While holding the connector securely against the lacing bracket, use pliers or similar tools to tighten the tie wrap, then remove any excess length.
