There are four different types of connectors found on various 4D models. The DB-9 serial port connectors, which are found on the

Challenge, Onyx, Personal Iris, and PowerSeries machines, have the following pin assignments.

Pin # Signal Name

TD Transmit Data

RD Receive Data

RTS Request to Send

CTS Clear to Send

SG Signal Ground

DCD Data Carrier Detect

DTR Data Terminal Ready

The Challenge and Onyx systems supply an RS-422 port. This RS-422 port uses a DB-9 serial connector that have the following pin

assignment:

Pin # Signal Name

DTR Data Terminal Ready

TXDL Transmit Data Low

RXDL Receive Data Low

DCD Data Carrier Detect

CTS Clear to Send

SG Signal Ground

TXHD Transmit Data High

RXDH Receive Data High

RTS Request To Send

In order to support peripherals which draw power from the host system, the Challenge and Onyx systems provide two powered-

peripheral serial ports. These ports have a DIN-8 connector. The powered ports share the tty2 and tty3 signal lines with the standard DB-

9 connectors; if the DB-9 connector for tty2 is already in use, you cannot use the powered peripheral connector for tty2. Similarly, if

tty3's DB-9 connector is connected to a peripheral, the powered peripheral port connected to the tty3 signal lines cannot also be used.

The powered peripheral ports have the following pin assignments.

Pin # Segnale Nome

DCD Data Terminal Ready

CTS Clear To Send

STEREO Stereo Field Sync

RD Receive Data

TD Transmit Data

SG Signal Ground

GND Ground Point

V10P 10V Supply
