With a multi-protocol DB-9 connector (RS-232, RS-422, and RS-
485), and RJ-45 type 10/100 Mbps Ethernet port for twisted pair
connection, the CSE-D9TX media converter facilitates integration
of asynchronous network devices with a TCP/IP-based Ethernet
network without requiring removal, replacement, or modification
of the existing serial cable infrastructure. Twisted-pair transmission
at 100 Mbs is 100 meters over Category-5 UTP cable.
The design of the CSE-D9TX allows for east implementation –
essentially, a straightforward "plug-and-go" operation. Additionally,
the compact form factor of the device translates into standalone
(desktop) or wall-mounted installation flexibility.
