6 Interface with GYDA and RS-422 command set
All commands follow the flashlink protocol and can be used for direct control access to
the modul. The control system can either be a GYDA-SC or a third-party control
system with integrated flashlink protocol. The module can also be manually controlled
with a VT100 compatible terminal program.
The protocol can be found on our web page; http://www.network-electronics.com
