Rear Panel Overview
This section briefly summarizes the features of the MB-651 rear panel.
Figure 2.2 MB-651 — Rear Panel
1. SDI IN BNC
This is the 3G/HD/SD SDI input signal.
2. SDI OUT BNC
This is a reclocked copy of the SDI input signal.
3. MONITOR Ports
These connectors provide analog audio. For a -20dBFS input, there will be a +4dBu output.
4. GPIO Port
Shorting the I pin to the G pin will mute the front speakers, and the audio level on the rear
monitor ports will be controlled by the front volume knob.
5. DIP Switches
SW1 and SW2 are used in conjunction with the DashBoard menus to set the IP Address of the
Monitoring Bridge. Refer to the section “ Configuring the DIP Switches ” on page 2-7 for details.
SW3 is used to override the Master Password for the Monitoring Bridge. This password limits
access to the Monitoring Bridge.
6. ETHERNET Port
Each Monitoring Bridge includes an Ethernet port on the rear panel that is used for
communication with DashBoard and software upgrades via DashBoard.
7. Power Supply Connections
These are the connectors for the primary ( PSU1 ) and optional redundant ( PSU2 ) supplies.
8. Power Cord Bracket Inserts
Install the provided brackets to help retain the power cords to the Monitoring Bridge chassis.
