Crestron DM-PSU-ULTRA-MIDSPAN Installation Manual

DM-PSU-ULTRA-MIDSPAN
DigitalMedia™ Ultra Midspan PoDM++ Injector
Installation Guide

Description

The DM-PSU-ULTRA-MIDSPAN provides two PoDM++ power sourcing equipment (PSE)
ports designed to power DM 8G+ PoDM powered devices (PDs). Each PoDM++ port of
®
the DM-PSU-ULTRA-MIDSPAN can supply up to 45 watts of power to a PoDM++,
PoDM+, or PoDM powered device. (Due to the inherent power loss over CATx cable, a
maximum of 40 watts is delivered to the powered device.)
The DM-PSU-ULTRA-MIDSPAN can simultaneously power a DM 8G+ transmitter and
receiver in a standalone con guration while passing data between the two devices.
The DM-PSU-ULTRA-MIDSPAN can also power a touch screen that has a DM 8G+ input
(for example, a TS-1542-C).
NOTE: The DM-PSU-ULTRA-MIDSPAN supplies power to a connected device only if
the device requests power. As a result, the DM-PSU-ULTRA-MIDSPAN can be
connected to the PSE port of a device that does not require power from the
DM-PSU-ULTRA-MIDSPAN (for example, a DMPS3-4K-150-C).
NOTE: The DM-PSU-ULTRA-MIDSPAN is compatible with HDBaseT Alliance
speci cations and can be used to supply up to 30 watts of power to IEEE 802.3at
compliant HDBaseT devices. (Due to the inherent power loss over CATx cable, a
®
maximum of 25.5 watts is delivered to the HDBaseT PoE+ or PoE powered device.)
