HARDWARE
The Apantac Tahoma Multiviewer Platform consists of 4 different sizes of mechanical frames to
serve the needs of broadcast, professional AV and surveillance markets. These frames are ½
width of 1 RU, 1 RU, RU and 3RU. Each Multiviewer frame has a unique IP address, which
allows a PC/laptop to easily connect and configure the display layouts.
The Tahoma LE consists of 4 electronic elements;
1. VPM -> Video Processing Module
2. URM -> Universal Receiver Module
3. CPM -> Control module
4. PSM -> Power Supply Module.
The URM module allows flexible field upgrades from composite video all the way to 3G HD-SDI
by simply swapping out a board. Future upgrades to computer/data inputs and network (ASI)
inputs are also available.
