CONNECTING MULTIPLE PMVC4 UNITS

Remember, when cascading PMVC4s, loop from the multiviewer with a lower ID to the multiviewer with a higher ID. Also, the following

additional steps are required when connecting multiple units.

1. Use a ﬂat head screwdriver on the rotary Unit ID switch to set the ID of the ﬁrst multiviewer in the display group to 0. This identiﬁes it in the

software as the ﬁrst multiviewer. Change the ID of every additional multiviewer in the group by increments of one; for example, the next

multiviewer will have an ID of 1. Do not use F, which is for testing only.

2. Connect a 10-inch (25.4-centimeter) DB9 serial cable from COM OUT on unit 0 to COM IN on the next unit, which is unit 1. Repeat until you

reach the last unit in the group.

3. Connect a DVI looping cable from Cascade/In on unit 0 to Cascade/DVI Out on the next unit, which is unit 1. Repeat until you reach the last

unit in the group.

Connecting Multiple PMVC4s

CONNECTING A SINGLE PMVR2

1. Connect any DVI inputs (such as from a VMX300 video management system) to the DVI 1 and 2 connectors or any VGA inputs (such as from

a DX8000 series digital video recorder) to the VGA 1 and 2 connectors on the back of the PMVR2.

NOTE:

You can have either DVI

VGA, but not both on the same channel. However, you can have DVI

and

VGA if you put them on

different channels; for example, DVI on DVI 1 and VGA on VGA 2.

2. Connect the male end of the 6-foot (1.8-meter) DB9 serial cable to COM IN on the PMVC4. Connect the other end (with the RS-232-to-

RS-485 converter) to the PC’s COM port.

3. Connect either a DVI looping cable from Cascade/DVI Out or a VGA looping cable from VGA Out to the display monitor.
