Controlling Switching Relay-4 and 8 from a third party controller

The Neets Control SR-4 can be controlled by either I/O's, RS-232 or LAN.
Using simple digital outputs on a third party controller gives you fast access to control the high power relays in the SR-4.

RS-232
Controlling the SR-4 by RS-232 is done by using the 3. party protocol that is described below. The default settings is 19200 8N1 and it offers loop through function to control a 2. RS-232 device. Also access to the 4 I/O's are available in both push and pull mode.

LAN control
Controlling the SR-4 by LAN is done by using the 3. party protocol that is described below. Connect by a TCP connection to port 5000. Also access to the 4 I/O's are available in both push and pull mode. The 2 RS-232 port can be used by connecting to port 5011 and 5012. This opens a transparent LAN <->RS-232 gateway. The speed setting of the RS-232 ports is done on LAN port 5000 using the attached setup commands.

Only one connection can be made to each port.
