DTE CABLE CONVERTER
3.3 Power supply connection
To supply the converter, the external power supply of 6V via SCJ 2.5mm connector
(yellow LED labelled 6V indicates it) or via 9 contact (IN+8V) is used, e.g. from
the DTE. The green LED labelled 8V indicates this supply. The DTE receives the
external supply information via OUT+5V signal. This arrangement enables to back
up the converter supply. The external supply 6V is isolated from the RS-422 link.
Maximum take off is 170mA.
Caution!
Do not connect the DC connector if the supply is on.
