Sync termination switches
Each input board supports 32 (two columns on the back panel) physical inputs. In
a sync BME, the first eight physical inputs on each input board are equipped with
sync termination DIP switches. Each switch provides the option of selecting either
510 ohms or 75 ohms. See Changing the Sync Termination in chapter 6, Upgrades and
Maintenance, to tailor the sync termination for non-TTL input sync.
The physical inputs with sync termination switches are:
• Inputs 1 through 8 on input board 1
• Inputs 33 through 40 on input board 2
• Inputs 65 through 72 on input board 3
• Inputs 97 through 104 on input board 4
The 75 ohms position is required only for an input with non-TTL sync, greater than
5V p-p. The normal position is 510 ohms. The switches provide a way to condition
non-TTL sync levels greater than 5V p-p, enabling the sync to be properly passed
from the input to selected output(s).
IP parameters initialization
The Matrix 12800 System Virtualization/Control software, which runs in a
Windows-type computer and communicates with the matrix switcher via the
RS-232/RS-422 ports or the Ethernet port on BME 0, provides an easy way to create
or edit the IP parameters required for WAN or LAN control of the switcher.
See Ethernet protocol settings in chapter 3, Virtualization/Control Software.

Matrix 12800 Switchers • Installation
CAMBOARD Electronics
An input that produces an out-of-sync display, a display that is rolling
vertically and/or tearing horizontally, could indicate a non-TTL sync input. A
device that is known to output non-TTL sync levels (greater than 5V p-p)
should be connected to one of the inputs with sync termination switches, and
the switches for that input should be set to the 75 ohm position. If you're not
sure, check the specifications in the user's manual for the input device.
If your Matrix 12800 switcher was previously set up for RS-232, and your
computer comm port uses RS-422, you must change an internal DIP switch.
See chapter 6, Upgrades and Maintenance, for details.
