9.4.1. General Information

There are two types of devices in general serial communication:
Data Terminal Equipment: Data Terminal Equipment (DTE) is an end instrument that converts user
▪
informationintosignalsorreconvertsreceivedsignals.TypicalDTEdevices:computers,LCDtouch
panels and control systems.
Data Circuit-terminating Equipment: Data Circuit-terminating Equipment (DCE) is a device that sits
▪
between the DTE and a data transmission circuit. It is also called data communication equipment and
datacarrierequipment.TypicalDCEdevices:projectors,industrialmonitorsandamplifiers.
Among others the pin assignment is different between DTE and DCE.
Pin 2:
Pin 3:
RD: Received Data (digital input)
TD: Transmitted Data (digital output)
Different type of serial cables must be used between different serial devices.
DTE
DCE
* In general contact DCE with DCE by tail-circuit serial cable.

9.4.2. Types of Serial Cables

Straight Serial Cable
Straight pin-outs both ends.
Devices may have male or female plugs and their type can be straight or null-modem cables.
ATTENTION!
The cable type does not depend on the plug type.

9.4.3. Serial Device Types

The types of VINX devices from serial data transmission point of view are the following:
