Thank you for purchasing this RS232 to TTL/CMOS Converter. It is

designed for your PC, workstation, thin client, or server to

provide an instant conversion solution for the device that

needs RS232 interface in TTL or CMOS voltage level. It provides

a DB9 female connector (DCE, with standard RS232 signals, TXD, RXD,

RTS, CTS and GND) that can be connected directly to your PC’s

RS232 port. The product is powered by the RS232 signals so it does not

need any DC power from an external AC Power Adapter.

Features:

✓Provides one RS232 to TTL/CMOS Adaption

✓Supports 4-Signal RS232 Conversion: (TXD, RXD, RTS, CTS, GND)

✓Supports DB9 Female (DCE) to DB9 Male (TTL/COMS) Connector

Conversion

✓Supports 5V and 3.3V Tolerance Signals

✓Signal Levels are Inverted by the Converter Similar to Standard RS232 but

in TTL/CMOS Swing Level

✓Supports Baud Rate up to 115.2 Kbps

✓Port-powered, no External Power Required

✓No Driver Required for All Operating Systems

RS232 to TTL/CMOS Converter

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 this Converter’s DB9 female connector, connect the

TTL/CMOS RS232 Device to the Converter’s DB9 male connector (with a

cable) .
