Congratulations on your purchase of a StarTech NETRS232. NETRS232s connect serial
devices to Ethernet networks.Any serial device—POS equipment,factory machinery,
monitoring hardware,or security devices, for example—can send its information to the
NETRS232.The NETRS232 places the serial data in a TCP/IP wrapper and sends it out its
Ethernet port. Data moving the other direction,from the Ethernet side of the
NETRS232 to the serial device,undergoes the same process in reverse.StarTech
NETRS232s use industry-standard hardware interfaces and are supported in Windows®
NT4,Windows®2000, Linux, and QNX.
With a NETRS232,you can:
• Network serial devices
• Make devices available to multiple users
• Manage multiple serial devices from a single PC
• Eliminate long dedicated serial runs
• Stop using costly PCs as dedicated serial port servers
• Remotely access and control serial devices
• Eliminate long-distance phone-modem charges
Included with your package, you should have the following:
• StarTech NETRS232
• Power supply
• Quad DB-9 cable (NETRS232 Quad version only)
• Installation diskette

of the network cable can be attached to either:
• an Ethernet hub or switch, using a length of standard Ethernet network cable
• a host PC directly,using an Ethernet cross-over cable.
Network status is indicated by two LEDs on the RJ-45 connector.The left (yellow) LED
indicates network activity.It is on by default, turning off when network activity occurs
at the NETRS232.The right (green) LED indicates a network link.It is off by default, but
lights when a network link exists.
