INTRODUCTION
FCC RADIO FREQUENCY INTERFERENCE STATEMENT
This device complies with part 15 of FCC rules. Operation is subject to the following two conditions: (1) this device
may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a class A digital device, pursuant to Part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
Changes or modifications not expressly approved by BUF Technology could void the user’s authority to operate
this equipment. Shielded cables must be used with this equipment to maintain compliance with FCC regulations.
WARRANTY STATEMENT
BUF Technology warrants that the equipment it manufactures is free from defects in materials and workmanship.
Equipment that has been operated within its ratings and has not been subjected to mechanical or other abuse or
modification and has failed because of such defects, will, at the option of BUF Technology, be repaired or replaced
if it is returned, freight pre-paid, to BUF Technology within two years from the date of shipment. Equipment that
fails under conditions other than described herein will be repaired at the price of parts and labor in effect at the time
of repair.
This warranty is in lieu of all other warranties, express or implied, including, but not limited to, any implied warranty
of merchantability or fitness for a particular purpose. BUF Technology is not liable for any consequential damages.
OVERVIEW
The VTC-4000 Multiple VTR Editing Control System provides a user friendly vehicle for the remote control of
professional and broadcast videotape recorders, DDRs/servers, digital audio decks, and other devices. Any VTR
or other device that conforms to the SONY P2 remote control protocol can be controlled. Up to ten devices can be
controlled separately or together in groups of any organization. Separate VTR select keys provide fast and easy
selection of devices, either individually or ganged. LEDs indicate that a VTR is in remote with tape loaded, that the
VTR’s scanner is up and ready, which VTRs are enabled for recording and which VTRs are enabled for control.
Multiple VTR editing is supported with any number of VTRs as record machines, each with independent
insert/assemble status and channel enables. Mixed timecode types are supported, and all functions work through
midnight (e.g. 23:59:55:00 is ten seconds less than 00:00:05:00, rather than 23:59:50:00 more).
A switch option is available that allows control of each VTR to be switched to another control system, but limits the
number of controllable devices to six. Each of six RS-422 controller ports are routed to each controlled device as
directed by the control panel.
VIDEO SERVER CONTROL USING VDCP PROTOCOL
This version of the VTC-4000 system is optimized for control of videotape based recorders, however it is capable of
controlling video servers in timecode only mode (clips must be loaded at the server, then transport functions can be
controlled like a VTR). A server optimized version is available, called VTC-4000-BC, that allows control of video
servers using the VDCP video disk communications protocol. The BC version uses the same hardware and
requires only a firmware change. Clip names can be viewed, sorted, and selected for playback using a PC running
the companion BUFclips software. The VTC-4000-BC also supports the SONY VTR control protocol, and server
channels and VTRs can be controlled simultaneously. Certain features involving synchronization are not supported
by the VTC-4000-BC, including tape based editing. The clip based features of BUFclips are optional, requiring a
USB software security key (Dongle). Also, the -RS (RS-232) option is required.

to the VTC-4000-BC with BUFclips.
