Protocol
The devices use a simple ASCII-based protocol over an RS-232 cable.
The default settings are (device-dependent), e.g., 1200 8N2, but the devices usually have a menu where the user can change the baud rate, parity settings, and so on.
There are two different packet lengths (also user-configurable via the menu): 14-byte packets and 15-byte packets.
See e.g. the KERN EW/EG-N/EWB series user manual for more protocol details.
