Product Names: HDBT-IN4-F32 Input Module for VS-3232DN
Date: July 2016
Introduction:
This Kramer technical note describes card population limitations of HDBaseT input cards
(modules) when installed in the VS-3232DN matrix switcher.
The VS-3232DN frame limits the use of up to four HDBT input cards per chassis
and dictate where they can be installed.
Cards Population Rules
The VS-3232DN chassis is divided into two groups of four input and four output cards for
a total of 16 cards.
When more than one HDBT input card is used, the following guidelines are recommended
(see following illustration):
Install a blank spacer in the first position (#1).
Install the first HDBT card in the second position (#2).
Install the second HDBT card in the third position (#3).
Install a third HDBT card (if required) in the fourth position (#4).
If a fourth HDBT card is required, install a blank space in position #5
and the card in position #6.
There is no limitation on the number or type of output cards that can be installed.

Example Installation:
The following example shows a VS-3232DN populated with four HDBT input cards
(maximum) and two HDMI input cards.
The chassis with HDBT cards is populated in the following way:
For effective air circulation, all empty slots must be closed with blank panels.
Input group 1, position #1 (IN 1-4) must be empty and covered with a blank panel.
Input group 1, positions #2, #3, #4 (IN 5-8, IN 9-12, IN 13-16) house HDBT cards.
Input group 2, positions #5 (IN 17-20) must be empty and covered with a blank
panel.
Input group 2 position #6 (IN 21-24) houses one HDBT card.
Input group 2 positions #7, #8 (IN 25-28, IN 29-32) may house HDMI or cards other
than HDBT.
Output slots can be populated with any combination of output cards.
Output slots that are not used must be covered with blank panels.
