About Both TPX Switcher Models

The TPX switchers are single box solutions to simple twisted pair routing applications (figure 1-1). Each input and output is individually isolated and buffered, and any input(s) can be switched to any one or all outputs with virtually no crosstalk or signal noise between channels.

The TPX 88 switchers support I/O grouping, a feature that lets you virtually divide the matrix into up to four smaller sub-switchers, making installation and control easier. I/O grouping allows you to separate different signal types to avoid connecting signal types from different, incompatible, transmitter/receiver families.

The TPX matrix switchers are housed in rack-mountable, 1U high, 17" wide metal enclosures. The appropriate rack mounting kit is included with each switcher, allowing you to mount the switcher in a standard 19" rack. Each model has an internal 100 VAC to 240 VAC, 50/60 Hz, 25 watts, auto-switchable, power supply that provides worldwide power compatibility.

Many twisted pair transmitters and receivers have the ability for one component of the pair to provide power for the other (such as a TP R BNC A providing the power for a TPT BNC).

The TPX 88 cannot power connected twisted pair transmitters and receivers. The TPX 88 cannot switch the power that a twisted pair transmitter or receiver supplies to a twisted pair receiver or transmitter.

In a twisted pair system that includes a TPX 88, both the twisted pair transmitter and the twisted pair receiver must be powered locally. The appropriate power supply is included with the transmitters and receivers.
