2−91 VM 3000 Installation and Operating Manual
Sony Installation Notes
Only one Sony VTR can be connected per port.
Late model Sony machines use a remote control protocol referred to as Sony serial, and these can be connected directly to
individual ports of a VM/SI 3000 board. Sony serial machines include the BVH−2000, BVH−2500, BVU−800, BVW−10,
and BVW−40.
Older models require connection through parallel or semi−parallel interfaces. See page 2−89.
Ampex Installation Notes
Only one Ampex VTR can be connected per port.
Late model Ampex machines use a remote control protocol referred to as Ampex serial, and these can be connected directly
to a VM/SI 3000 board. Ampex serial machines include the VPR−3, VPR−6, and VPR−80. See Figure 2−106.
Note 1: Protocol for these serial machines is similar to ESbus and includes a device addressing scheme. The ad-
dress of each Ampex VTR must therefore be entered on the Machine Control Devices table (page 5−140); this is
true even when only one VTR is on the bus. The machines are usually shipped with an address of 80A2 hex.
a. VPR−6 and VPR−80 Address Setup
(1) Enter setup mode 13 (setup−1−3−enter).
(2) Enter a “1” to set an address of 80A2; or enter a “2” for address 80A4. (CMX editors may expect the 80A4
address.) If the number “0” is entered, the VTR will not respond to any address.
b. VPR−3 Address Setup
(1) Remove PWA #20 (the Control PWA).
(2) Set rotary switches S4, S5, and S6 to “0.”
(3) Set rotary switch S3 to “1” for an address of 80A2. If the switches are all set to “0,” the VTR will not respond
to any address.
(4) Reinsert PWA #20 into the card cage.
Older models require connection through parallel or semi−parallel interfaces. See page 2−89.
