1. DTE stands for Data Terminal
Equipment: these include Computers,
PLC's, and most devices which are not
used to extend communications. Think
COMPUTER
for
DTE
.
2.
DCE stands for Data Communications
Equipment: these includes devices
intended to plug directly into a DTE
port, Modems and devices that extend
communications like a modem, such
as RS-422, RS-485, or Fiber Optic
converters or Radio Modems. Think
MODEM
for
DCE
.
3. On the DCE (female) side, Pins 1, 4,
and 6 are tied together internally.
4. On the DTE (Male) side, Pins 4 and 6
are tied together internally.
