LAVA Ether Serial Link Eight Port Quick Installation Guide LANAA Rev A01 AO Getting Started Congratulations on your purchase of a LAVA Ether Serial Link Ether Serial Links 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 Ether Serial Link The Ether Serial Link 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 Ether Serial Link to the serial device undergoes the same process in reverse LAVA Ether Serial Links use industry standard hardware interfaces and are supported in Windows NT4 Windows 2000 Windows XP Windows 2003 Linux and QNX With a LAVA Ether Serial Link you can e Network serial devices e 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 LAVA Ether Serial Link Power supply Two quad DB 9 cables 8 DB9 Cabled version only e Installation diskette Quick Installation Guide Q Hardware Setu 1 Connect the power supply to the Ether Serial Link and to AC power
