Getting Started Overview 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 RS-422 pinouts are not the same across Comtrol product lines.
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.
Data-Only Null-Modem Cables Data-Only NullModem Cables If no hardware flow is required, use the pinouts in the following figure. If you are using a 3-wire cable and you need control, use software flow control.
