Introduction
1.2 Summary of Features
Physically and functionally the EM1500 is a black box. As any good black box should be, the EM1500 is
simple to use. No programming is needed. The tight integration of hardware and software offers unparal-
leled reliability. Quick configuration over Ethernet, using a web browser or the stand-alone configuration
program, is easy and convenient.
The performance of the EM1500 is:
•
Net long term throughput of 460800 bps full-duplex (FDX), assuming Ethernet/Internet link is not
the bottleneck.
•
Short term burst rates up to 1Mbit/sec net.
•
Any one port may achieve up to 230400 bps FDX.
The EM1500 interfaces with all types of serial devices: modems, sensors, card readers, bar scanners, print-
ers, etc.

Having two EM1500s allows you to create a transparent serial bridge, thereby use some of the more
advanced software features, such as packetization and protocol conversions. For more information on
these features, see .
