TPMC-15/17-L Series

NOTE: When transmitting S-video, luminance uses the green video pathway and

chrominance uses the red video pathway. When transmitting composite video, the

signal is carried on the blue video pathway.

NOTE: When using CresCAT-QM wiring, four additional wires are included for

making Cresnet connections.

When connecting multiple QM devices, the route between a QM origination point

(transmitter) and a QM endpoint (receiver) cannot have more than two midpoints

(e.g. QM-MD7x2 or other QM switchers). Refer to the following diagram when

configuring a QM network.

NOTE: The aggregate length from transmitter to receiver cannot have a delay skew

of more than 22 ns.

The TPMC-15/17-QM-L is not a switcher, but a transmitter/endpoint. Therefore,

even when designated as the endpoint from two midpoint switchers, the QM output

of the TPMC-15/17-QM-L can become another transmitter sending RGB video at the

touchpanel’s native resolution and aspect ratio. Refer to the following diagram.

This QM-RMCRX-BA does

not violate the two-midpoint

rule as it is receiving an

RGB signal from the

TPMC-15/17-QM-L

transmitter.

This TPMC-15/17-QM-L

acts as both an endpoint for

signals from the QM-WMC

origination points AND a

QM transmitter to the

QM-RMCRX-BA.
