VFOM-1 Setup and Installation
Installation and Use
Install the unit away from heat sources, such as vents and radiators, and in rooms with adequate
ventilation. Ensure that air can circulate freely behind, beside, and above the unit. Do not exceed the
maximum ambient operating temperature of 18°-108° F (-8° - 42°C). Be aware of conditions in an
enclosed rack that may cause the temperature to exceed ambient room conditions.
To install a VFOM-1, first fit a personal anti-static grounding strap and continue to wear it throughout the
following procedure.
Power down the VA-8600 by removing the power cord. Do not attempt to install the VFOM-1 card in a
powered VA-8600 device. In order for the power supply capacitors to discharge, allow the amplifier
power to remain off for at least five minutes before proceeding.
Remove the VA-
8600 top cover (6 x #4x¼” self-tapping screws, 3 at front, 3 at rear; 2 x #6 machine
screws, center top of cover).
Viewing the rear of the VA-8600, locate the module in Slot 10. Remove the blank panel from this
position (remove 3 x #4x¼” self-tapping screws, slide panel upward).
Viewing the amplifier from the top, on the motherboard locate and remove the #4-32 machine screw
marked 10 (near connector J10, AUX PWR).
Fit the VFOM-1 module (with ribbon cable attached) by sliding the rear panel into the position formerly
occupied by the blank panel.
Re-fit the three rear panel screws and re-fit the motherboard screw through the VFOM-1 mounting
bracket (marked MH3 on VFOM-1 PCB).
Locate the NM-1 network module adjacent to the newly fitted VFOM-1 module; on the NM-1 locate
connector To NM-1, J17.
Plug the free end of the ribbon cable from the VFOM-1 module into J17 of the NM-1 module, ensuring
that pins are aligned and that the polarizing stripe on the cable is toward the top of the VA-8600 at both
the NM-1 end of the cable and the VFOM-1 end of the cable.
Check that all screws are tight and re-fit the VA-8600 top cover.
Each VFOM-1 module must be enabled in the Vocia software.
The VFOM-1 module is now ready for use.
