RS232 Isolator and Surge Protector
3. Installing the RS233 Isolator
Since this isolator hardware unit should be powered by the external
power source, please connect the 5V AC power adapter or the
USB-to-Power-DC-Jack Conversion Cable to make sure the unit works
properly. If you are using the USB-to-Power-DC-Jack Cable instead of the AC
adapter, please make sure that the USB port is at Host side (the same side
as the DB9 female connector), DO NOT connected to the USB port at the
device side (the same side as the DB9 male connector), otherwise, the unit
won’t work and the DC power was passed though the isolation circuits so the
isolator will not function properly.
1.
Use static electricity discharge precautions.
Remove possible static discharge potential from any objects that
the converter may come in contact with before installation. This
can be accomplished by touching a bare metal chassis rail after
you have turned off the power.
2.
Locate an unused PC’s RS232 port (with DB9 male connector,
configured as DTE), connect it to the Isolator’s DB9 female
connector with a RS232 cable, find another cable to connect the
RS232 Device to the Isolator’s DB9 male connector.
