Using a Programmable Serial
Gateway
This chapter describes how to develop a gateway for a user-defined
EIA-232 serial protocol. The SLTA-10 is shipped with SLTA
firmware that allows it to be used as a LonTalk network interface
for network management, monitoring, and control. When the SLTA
firmware is installed, the data passed between the firmware and
the host application via the EIA-232 port is in the format of
LonTalk protocol application buffers. Serial gateways are
developed using the models 73381,73382,73383, or 73384 PSG/3
(Programmable Serial Gateway). These products allow you to
replace the SLTA firmware with your own firmware, enabling
custom protocols to be translated into LonTalk.
