KeyShot Series RS-422 Interface Card
The RS-422 Interface is intended for operation with a VTR,
controller or a host computer. It provides the advantages of RS-
422, which allows for long cable runs. With low loss, low
capacitance cable, the RS-422 Interface Card can accommodate
cable runs up to 1km.
The RS-422 Interface has a female, 9 pin, D-Sub connector. The
interface can be configured to connect to either a deck or a host.
Five jumpers on the interface card configure the pinout. All five
jumpers must be places in either the “To Computer” or “To
Machine” position. The port is set to communicate at 38400
bits/sec, 1 start bit, 8 data bits, 1 stop bit and odd parity.
