1. REVISION HISTORY

120403 Rev. 2.1 Company header information revised.

Added DNF Controls Limited Warranty.

2. DESCRIPTION

The SR6-SONY, Serial In to Parallel Out Converter, provides simple emulation of the SONY
BVU-800.

The SR6 converts the following SONY serial commands into six open-collector GPIs:

RECORD, PLAY, STOP, REWIND and FAST FORWARD

Additionally, the SR6-SONY accepts the following 6 tallies from the controlled device, to provide
real-time status to the control point:

LOCAL, RECORD, PLAY, STOP, REWIND and FAST FORWARD

NOTE: It is recommended that an opto-isolator be used on each tally
line from the Controlled Device to the SR6-SONY.

The SR6-SONY can be configured to control an AMPEX VPR-2 or provide a standard 250
millisecond, pulsed GPI output, using the Rear Panel DIP switches.

3. INSTALLATION

1. Plug one end of a 9-conductor, RS422 serial cable into the 9-pin connector on the rear of the SR6­SONY. Plug the other end of the cable into the 9-pin connector on the controller.

2. Plug the 9-pin D-type female connector on the POWER SUPPLY into the male 9-pin connector on
the rear of the ST100.

Plug the AC connector into a wall outlet, 90 VAC - 265 VAC, 50-60 Hz.

3. Select REMOTE operation on the VTR's front panel.

INSTALLATION for Standard VTR

1. Set Rear Panel DIP Switch #6 to OFF.

2. Wire the desired command lines to the controlled VTR, per the Standard VTR
Interface Connector chart.

3. Wire the Command Common to the VTR Command Input Common.

4. If Controlled Device Status Tallies are to be returned to the controlling point,
ALL tallies must be connected: Local, Play, Record, FFWD, Rewind and Stop.
It is recommended that an opto-isolator be used on each tally line from the
Controlled Device to the SR6-SONY.

5. Set Rear Panel DIP Switch #5 to ON.

Installation is complete.

INSTALLATION for AMPEX VPR-2

Wire SR6 pin #9 to AMPEX pin #31, Ground.

Wire SR6 pin #3 to AMPEX pin #5, Record.

Wire SR6 pin #4 to AMPEX pin #1, Play.

Wire SR6 pin #5 to AMPEX pin #15, Stop.

Wire SR6 pin #8 to AMPEX pin #20, Shuttle Command

Wire SR6 pin #6 to AMPEX pin #16 through 27K ohm, 1/4 Watt, series resistor.

Wire AMPEX pin #4 (+12 Vdc) to AMPEX pin #16 through 100K ohm, 1/4 Watt series
resistor.

The value of the 27K and 100K resistors can be adjusted for a desired shuttle speed per
the following:

When pin #16 voltage is:

Î 5 volts, the tape shuttles forward.
Í 5 volts, the tape shuttles reverse.

The further away from 5 volts, the faster the shuttle speed.
The closer to 5 volts, the slower the shuttle speed.
