EM 122
Generic RS-232 Serial line
This cable comprises a multi purpose serial line. It provides interface with any peripheral
unit. One end of the cable connects to the local unit
(DTE)
with a 9-pin D-connector,
while the other connects to the peripheral
(DCE)
as described in the peripheral unit's
documentation.
In many cases, only the
RxD
,
TxT
and
GND
pins are used. Twisted pairs are sufficient
in the cable.
