Drivers: MAX 491 or equivalent RS-485/RS-422 transceiver
Termination: Optional 120 ohm resistor across receive signal

Using the SS422

RS-232 connection:

The male DB9 connector on the SS422 is designed to plug directly into the female DB9 connector on any Industrologic product or other device that has +5 volts power available on pin 9 of the connector. Some Industrologic products have jumpers associated with their serial ports that select whether pin 9 is connected to 5 volts, unregulated (+V), or nothing. If this choice exists, 5 volt option must be used. Do not use the unregulated (+V) option!

RS-422 connection:

The following drawing shows the pinout of the RS-422 signals on the female DB9 connector on the SS422 and how they should be connected to a SMPTE "Master" device. The ground connections shown are typically the shields (if they exist) present in the cable used to do the RS-422 wiring, and may not be necessary for all applications.

A 120 ohm termination resistor is available to be connected across the receive input pins if required by the application. The plastic jumper plug at P1 should be set to "N" for no termination, or "T" to connect the termination resistor.
