RS422/RS449/RS530 and X.21 Using the DIF101 Digital
Interface

The RS422 interface specification defines only the electrical voltages at

the interface and leaves the pin-out and meaning of the pins to the

hardware designer. The RS449 interface specification utilizes the

electrical specifications of RS422 but specifies a mechanical connector.

RS449 equipment is therefore electrically compatible with the

RoadRunner

RS422 interface when an appropriate adapter cable is

used. RS449 also specifies numerous control signals besides clock and

data, which are not used by the

RoadRunner

. The

RoadRunner

RS422

interface pin-out is specified in Appendix A.

The RS422 interface also has a separate clock for the transmitted and

received data. The RS422 interface can also echo the transmitter clock.

If the terminal equipment clocks the encoder data with the echoed

clock, the

RoadRunner

may be located up to 4000 feet (1219 meters)

from the terminal equipment without concern for encoder-to-clock

skew.

The X.21 (also known as RS530) interface specification is, in general, a

very complex specification. The general specification allows a

mechanism for communication between the customer equipment and

the network. This communication path can be used for things such as

dialing. A sub-set of the specification, called the leased circuit, used

here, restricts the interconnection to only clock and data and a very

simple control signal. The mechanical connector required is the DB15

with the pin-out specified in Appendix A. The electrical specification

for X.21 is identical to those of RS422. The X.21 interface has only one

clock for both transmit and receive signals.

Since the X.21 uses the RS422 electrical interface, the

RoadRunner

can

use the same connector for both interfaces. In the case of the X.21

interface, the single clock is used internally for both transmit and

receive timing. To change the hardware configuration of the DIF101

interface card between X.21 and RS422/RS449, change the position of

jumper J4 on the interface module. The jumper on positions 1 and 2

sets X.21 operation, and when on positions 2 and 3, the card is set for

RS422/RS449 operation.

Once the DIF101 module is installed, select the appropriate interface

type from the

RoadRunner
