Functional specifications

The Alfanet PC-Interface 2e gen. is provided with a real-time clock and display. This interface has
been developed as an intelligent interface between a Personal Computer (PC) and the RS485
network. The interface takes care of the communication between the PC and the network and is in
principle a transparent intermediary for messages from PC to the RS485 network and vice versa.
The interface can also store messages and log data in its internal buffer when the PC is not available
for communication with the interface or in case the PC is turned off.
Of all the messages coming from cool panels there are two messages to activate the relays on the
interface;
1) an alarm message to active relay 1
2) a log-buffer full message to active relay 2
The communication program for the PC requires MS Windows
