Introduction
The Valcom Baseband Video Switcher is a state of the art video observation product capable of operating in 2 distinct modes. As a standalone product, the system allows for video observation of up to 192 areas through up to 4 NTSC video monitors. When used in this stand-alone mode, camera control is achieved through the use of a Windows ® Based
Camera Administrative Tool.
When combined with a 5100 School Communications and Management system, the resulting configuration (a.k.a. PVBX) provides for both visual observation and audible communication to any of these 192 areas. The two systems are designed for seamless integration. The PVBX features automatic video synchronization to active audio connections. In other words, when a school administrator is talking to an area through the intercom, the PVBX will automatically display the video from that area on the appropriate monitor. Each of the 4 monitor outputs may be assigned to one of the 5100’s Administrative Phone ports to allow each to simultaneously view and converse with a different area.
In either case, a fully programmable idle loop is available to switch between designated cameras when the system is in an idle state.
The Valcom Baseband Video Switcher System is comprised of 3 parts:
A V-2954 controller for systems of up to 96 cameras, or a V-2958 controller for systems of up to 192 cameras
V-2960 Single Gang Camera(s)
V-2955 Video Camera Interface Unit(s) which each accommodate up to 24
V-2960 cameras

Roanoke, VA 24019

A fully expanded system would include one V-2958, eight V-2955s and 192
V-2960s.
The system uses VP-6124-P 24 VDC power supplies.
The V-2960 cameras are remotely powered and therefore do not require local power at each location.
Mounting
The V-2954, V-2958 and V-2955 units are intended for 19 inch rack mounting. The units will each occupy adjacent one-rack unit spaces. The
Baseband Video Switcher Master Unit should be installed above the V-
2955 unit(s).
The system power supply should be located no less than 3 and no more than 6 feet from the equipment being powered.

Software Setup
System setup and customization is accomplished through the EVPTL
Software Programming Tool. When this program is invoked, the following screen appears.
This screen provides 3 options for programming the V-2955.
Option 1 - The installation technician can specify the file name of previously saved V-2954/V-2958 programming (EVPTL Filename), or the file name of previously saved PagePac or 5100 programming. When choosing the latter, the V-2954 will automatically assign camera ports to each intercom station and will import the flexible architectural numbering and enhanced caller ID descriptions in order to create a seamless integration between camera numbering/descriptions and zone numbering/descriptions.
Option 2 – The installation technician can manually specify a configuration.
This allows the Baseband Video Switcher to be set up for use with a
PagePac or 5100 system without reading data from any database.
5614 Hollins Road
Roanoke, VA 24019
Page 10

Option 3 – The installation technician can retrieve the current programming from the V-2954/V-2958 Master unit.
Option 1 Details
When Option 1 is selected, the installer can simply enter, or browse for a previously saved EVPTL, PagePac or 5100 database file name.
5100 system database files have a
“.mdb” file name extension.
PagePac database file names have a “.p4p" file name extension.
VC-24/5105 database files have an
“.dat” file name extension.
EVPTL file names have a “.bvs” file name extension.
Click Finish once you’ve selected the database file.
If the installer chooses to browse for a previously saved file, the following screen will appear:
Page 11
5614 Hollins Road
Roanoke, VA 24019

If the database file that you selected is for a PagePac or 5100 system the programming tool will prompt the installer for some additional information.
The programming tool will then prompt you to identify how many V-2955 Camera
Interface Units and which master unit your system will feature.
Page 12
5614 Hollins Road
Roanoke, VA 24019

Option 2 Details
When Option 2 is selected, the installer can manually define which intercom system will be connected to the Baseband Video Switcher.
When specifying a
PagePac configuration, the installer will be prompted to define the number of
PagePac expansion units and the number of digits in the default numbering plan
(2 or 3).
Page 13
5614 Hollins Road
Roanoke, VA 24019

When specifying a 5100 configuration, the installer will be prompted to define the number of 24 zone station cards (1 – 15).
When specifying a VC-
24/5105 configuration, the installer will be prompted to define the number of expansion units and the number of digits in the default numbering plan (2 or 3).
Page 14
5614 Hollins Road
Roanoke, VA 24019

Option 3 Details
When Option 3 is selected, the installer can simply retrieve the programming from the Baseband Video Switcher. In order to make this connection and retrieve the programming, the installer must provide the system password; the default password is 825266.
Next, the installer must define which COM port on their PC is connected to the V-2954/V-2958.
Page 15
5614 Hollins Road
Roanoke, VA 24019

Once this connection is established the EVPTL
Programming Tool will automatically retrieve all current programming from the system. Following this data retrieval, the EVPTL prompts the installer to identify the Master Unit (V-2954 or V-2958).
Page 16

System Programming
If the database file that you selected is for a PagePac or 5100 system the
EVPTL Programming Tool will automatically sequentially assign the stations from the selected intercom to the Baseband Video Switcher system’s camera inputs. In the example shown below, we have a single V-
2955 Camera Interface Unit.
Video input 1 of the V-2954/V-2958 has been assigned to the V-2955 Camera Interface
Unit. Any of the 24 camera inputs on this V-
2955 may potentially be switched to Input 1.
Video inputs 2 - 8 of the V-2954/V-2958 have been assigned to single cameras.
Page 17

Roanoke, VA 24019

Clicking on Settings allows the installer to define general system parameters.
When the Baseband Video Switcher is used with a 5100 system, each of the 4 viewing monitors can be associated with an administrative port..
This association provides for the automatic synchronization between video and audio when that port is actively conversing with an area. The monitor/administrative port association can be redefined here.
When the Baseband Video
Switcher is used with a
PagePac or 5100 system, the camera that is viewed automatically switches to the intercom station involved in an active intercom connection.
Since the video selection can also be controlled from the
EVADM Camera
Administration Tool (PC), there could potentially be a

This can be changed conflict. System conflict resolution is determine here. here. Be aware that if the password is changed and forgotten, a factory repair will be necessary to program the unit.
The time shown on the viewing monitors can be synchronized to the intercom’s time (from
SMDR), or from the PC’s internal clock.

Upon clicking Idle Loop, the installer can determine which cameras will initially be included in the system’s idle loop. As a reminder, the idle loop is the sequence of cameras displayed on all of the monitors when the system is in an idle state. The idle loop can also be manipulated in the EVADM
Camera Administration Tool.
1) Click on the camera that you want to include in the idle loop
2) Click the add button to add the camera to the idle loop, Click the remove button to remove the camera from the idle loop.
3) Select the delay time
(seconds) before cameras in 1) Click on the camera input that requires modification. Note that

As previously stated, if the database file that you selected is for a PagePac or a 5100 system the EVPTL Programming Tool will automatically sequentially assign the stations from the selected intercom to the
Baseband Video Switcher system’s camera inputs. If the installer wishes to modify this default camera assignment, this is easily accomplished.
1) Click on the camera input that requires modification. Note that clicking on the + next to input 1 will expand the input and display all of the 24 camera inputs on the V-2955
Camera Interface Unit.
2) Choose and click on the desired camera arch number assignment. The programming tool will inform you of any conflicts (2 cameras with the same Arch number assignment).
Click select assigned arch numbers or descriptions requiring modification and click
Edit Arch Number and Name to make changes. Camera Arch numbers may only be edited if they are not associated with an intercom station.

Each 5100 system or PagePac station may be:
1) Associated with a video camera (Assigned Pageable)
2) Not associated with a video camera (Unassigned Pageable)
Video inputs that are not associated with an intercom station are denoted as Nonpageable.
Multiple video inputs with identical Arch number assignment are denoted as
“Conflict” and require corrective measures.
