Overview
RS-422 Pinouts
Getting Started
This document describes how to build cables for Comtrol products.
This chapter describes the standard Comtrol cables and the basic types of devices
that can connect to Comtrol products. It also explains the difference between
shielded and unshielded cables. This chapter covers the following topics:
• RS-422 Pinouts
• Standard Comtrol Cables
• DTE versus DCE
• Shielded vs. Unshielded
RS-422 pinouts are not the same across Comtrol product lines. For example, a DB9
loopback plug designed for a RocketPort model will not work on a DeviceMaster
model. When you build a cable make sure that you use the correct pinouts for the
Comtrol product. The following sections describes the valid pinouts and cabling for
each product:
• Building Cables for RocketPort Products
• Building Cables for DeviceMaster Products
Standard Comtrol Cables

DTE versus DCE
DTE versus DCE
Most devices, except modems, are Data Terminal Equipment (DTE) devices.
Modems are Data Communication Equipment (DCE) devices. Comtrol ports are
configured as DTE.
How you build a cable depends on which device your are connecting to (DTE or
DCE). For example, you need a null-modem cable to connect the COM ports (com1
or com2) on the computer or the DeviceMaster ports to printers, terminals, bar
code readers or DNC equipment. If you are connecting a DTE device to a DCE
device you need a straight-through modem cable.
• Straight-through cable (DTE to DCE) - Connects TxD to TxD and RxD to
RxD.
• Null-modem cable (DTE to DTE) - Connect TxD to RxD and RxD to TxD.
RS-232 DTE to DCE This topic describes how to build a straight-through cable. Use a straight-through
cable to connect to a DCE device.
Straight-Through Cables
The following figure shows the most common types of DTE to DCE cables. This
cable configuration works with most modems and is generally called a modem
cable.
Note: If you have a DTE to DCE interface but are uncertain as to which signals
are required, you can use a full 25-wire cable. The 25-wire cable is
constructed as shown in the following cable example, but the remaining
pins are not used.

Null-Modem Cables If you need RTS-CTS/DTR-DSR hardware flow control, you can use the pinouts
provided in the following example.
Note: If the wiring on the peripheral device differs from the one shown below,
adjust the pinouts accordingly. Refer to the manufacturer’s installation
document if you need help with connector pinouts or cabling for the
peripheral device.

Shielded vs. Unshielded
If the Comtrol device falls within the limits for a Class A computing device
established by the FCC, the serial cables used to connect the Comtrol device to the
external devices must be shielded. The cable shield must connected to the chassis
ground at both ends to reduce EMI. If the cable shield is not connected to the
chassis ground at both ends, the EMI radiation from your system may exceed the
limits allowed for FCC class A equipment. You can use an isolation device if you
experience problems with ground loops.
Refer to the statement on electromagnetic compliance in the Comtrol hardware
document to determine the FCC class for your Comtrol product.

RJ11 Serial Cables and Loopback Plugs
The RocketPort PCI/8J and Universal PCI/8J have eight standard RJ11 modular
connectors, located on the controller board mounting bracket. The ports are
numbered 0 through 7, with Port 7 being the connector closest to the bus.
The following RocketPort models support the female loopback plug for RS-232
port:
• RocketPort PCI
• RocketPort Universal PCI
• RocketPort ISA
Requirements There are no standards for the RJ11. Before you build the custom RJ11 serial
cable for your terminal equipment or device you should:
• Refer to the manufacturer’s installation guide if you need help with connector
pinouts or cables for the peripheral device.
• Supported RS-modes are described in the electronic document shipped with
your Comtrol device.
RJ11 Pinouts This topic describes pinouts for the RJ11 interface connector for an RS-232 port.
The following figures provide pinout information for the RJ11 jack plug and

RJ11 Loopback Plugs
A loopback plug is an RJ11 serial port plug with pins wired together. You can use
it with application software (for example, Test Terminal) to test serial ports.
To build an RJ11 loopback plug, wire these pins
together:
•Pins 3 to 4
• Pins 1 to 5 to 6
