| EM1500 Serial-Ethernet Bridge |
| Model EM1500 |
The EM1500 Serial-Ethernet Bridge is a device that converts multi-point
serial communications to a TCP/IP network. The EM1500 connects to and
network enables as many as 4 RS-232 serial devices simultaneously, while
also acting as master on a multi-drop RS-485 network. In addition, the
EM1500 provides an SPDT relay, 2 digital open collector outputs and 3
digital inputs suitable for interfacing to mechanical switches or logic
level circuits.
Success in today's marketplace demands rapid, low-cost access to information.
The EM1500 is designed to allow easy setup and monitoring via a "black
box" approach. No programming is needed. The tight integration of
hardware and software offers unparalleled reliability. Quick configuration
over Ethernet, using a web browser or the stand-alone GUI configuration
program, is easy and convenient.
The EM1500 interfaces with all types of serial devices: modems, sensors,
card readers, bar scanners, printers, etc. Having 2 EM1500s allows the
creation of a transparent serial bridge, thereby using some of the more
advanced software features, such as packaging and protocol conversions.
