Specifications and EM100 Modifications

There are five different EM100 sub-models in circulation: EM100-00, EM100-01, EM100-02, EM100-03, and EM100-04. Currently, only the EM100-04 is being manufactured so the information on EM100-00...EM100-03 is provided for your reference only.

The EM100-00, EM100-01, and EM100-02 devices were basically the same, with only minor changes made to the internal hardware (such as bypass capacitors on the internal PCB, etc.). We will refer to all three modifications as the EM100-02.

The EM100-03 has extended functionality compared to the EM100-02. There are two notable differences:

Memory size inside the device has been increased so the routing buffers of the EM100-03 are double the size of the buffers inside the EM100-02 (510 bytes in each direction vs. 255 bytes in each direction).
Ability to upgrade the application firmware through the network was added (this is facilitated by the NetLoader firmware) to the EM100-03. The EM100-02 cannot run the NetLoader and cannot be upgraded through the network.

The EM100-04 is a RoHS-compliant version of the EM100-03. The EM100-04 and EM100-03 are identical in every other way.
