RS232 to RS232 Isolator
Installation Guide
1. Introduction
Thank you for purchasing this RS232 (to RS232) Isolator and Surge
Protector. It is designed for your PC, workstation, thin client, or
server to provide an instant isolation solution for the RS232 serial
devices. It provides a DB9 female connector (DCE, with standard
RS232 signals, TXD, RXD, RTS, CTS, DTR, DSR, DCD and GND) that can be
connected directly to your PC’s RS232 port. An external 5V DC power
source should be applied to its input DC jack. The power source can
be supplied by either an AC power adapter or an USB-to-DC-Jack
conversion cable.
Features:
9Provides one RS232 to RS232 Adaption
9Supports up to 2,500Vrms Isolation for all RS232 Signals
9Supports all RS232 Signals (TXD, RXD, RTS, CTS, DTR, DSR , DCD, and GND)
9Supports DB9 Female (DCE) to DB9 Male (DTE) Connector Conversion
9Supports Baud Rate up to 921.6 Kbps
9+5V DC External Power is Required, Powered by AC Adapter or USB Port
with an USB-to-DC-Jack Cable
9Compact Size for Critical Applications
9No Driver Required for All Operating Systems

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.
