ESSEN
Hessen is a multidrop protocol, in which several remote instruments (slaves) are connected
via a common communications channel to a host computer. Slaves respond only to
commands sent by the host using their unique identification.
Important
The Hessen protocol is not strictly defined; therefore, while Teledyne API's application is
completely compatible with the protocol itself, it may be different from implementations
by other companies.
