Ethernet (10Base-T, 10Base-2) to Serial Converter
CE
Model SS1
Description
The Serial Server (SS1) is designed to make it easy to connect a serial port device to your network without a local
host. A remote PC or terminal can then be used to monitor, configure, manage, and send or receive data to the serial port
device through the LAN via telnet. This module can also connect any two asynchronous serial devices through the LAN
and between LAN's via routers when used in client-server mode (requires two modules). Connections will automatically
be opened when the units power up when in the client-server mode, eliminating the need for manual requests. A new
feature called EtherModem mode allows a serial device to treat the SS1 as if it was a true "Ethernet Modem", using
normal modem control and response strings such as "ATD", "ATE", +++, etc. This allows a single SS1 to connect to
multiple remote servers (either SS1's or telnet servers) under control of the attached serial device. Common applications
include remote data collection terminals, bar code scanners, building automation equipment, UPS's, climate control
devices, and multiplexers.
For easy connection to your LAN, model SS1 supports both BNC (10Base-2) and RJ45
(10Base-T) connections. The module will automatically adjust for each type of network connection. Power supply is
included.
