RS-4/U
Installation Instructions

Hardware
The RS-4/U adapter simply plugs into the RS232 port of the Sony model UVW-1200 or UVW-1400 videotape recorder. A standard, straight, 9-pin cable connects between the RS-4/U and the controlling video editor, usually equipped with an RS422 serial port. If the editor is a PC, then an RS232-to-422 adapter is also required at the PC COM port. The adapter derives its power from the RS232 port of the videotape machine.

Make sure that the UVW tape machine has its serial transmission rate set to 19200 baud for adapters marked with "ver 5.6"; otherwise, 9600 baud should be used for adapters marked with "ver 5.6a". This is set from within the on-screen menu of the UVW tape machine. Should it be necessary to change the UVW's baud rate, it is recommend that the baud rate be double-checked to insure that the change was actually accepted by the tape machine. The Remote/Local switch on the UVW's front panel also needs to be in the Remote position in order for the serial interface to control the deck. Timecode can always be read, though, even if the deck is in Local mode.

The controller baud rate does not need to be changed. It will see the RS-4/U adapter as just another RS422, "Sony Serial"-compatible deck operating at 38400 baud.

Software
There is no special software driver required for the RS-4/U, as it directly translates the de facto industry-standard "Sony Serial" protocol found on RS422.
