For an unbalanced input source, such as a 3.5 mm
audio TRS jack from a mobile device or PC, make the
following connections in the user cable: Connect XLR
pin 1 and 3 together (tying Common to Signal -). The
unbalanced signal connects to XLR pin 2 (). The
3.5 mm audio TRS to XLR Male cable that is provided
with the gateway is wired for unbalanced audio.
SMPTE Timecode
The gateway supports input of the following timecode formats:
Power and Connections
The SMPTE Gateway can use Power over Ethernet (PoE) or can be powered by USB. The following
connection methods are available:
• Ethernet only: Ethernet is used to supply power (PoE) and to transport timecode over the network
• USB and Ethernet: Ethernet sends SMPTE timecode over the network and USB is used only for power
• USB only: The gateway is powered by and sends converted timecode over the USB connection. In this
scenario, the USB connection must be made directly to the lighting console.

The rack mount variant of the SMPTE gateway can have the Ethernet connector installed on the front or
back of the unit. To switch the location, perform the following steps:
1:
Using a Phillips screwdriver, remove the four screws on the
bottom of the gateway and slide the cover off from front to
back.
2:
Using a Phillips screwdriver, remove the two screws from the
nuts securing the blank plate to the gateway.
3:
Remove the two screws securing the Ethernet connector to
the gateway.

Move the Ethernet connector to the desired location on the
gateway and secure with the two screws removed in step 3.
5:
Secure the blank plate to the other location using the screws
and nuts removed in step 2.

Slide the cover back on the gateway, from back to front and
secure with the four screws you removed in step 1.
