RS232 Communication Option
The 301 Controller can be supplied with the capability to communicate with other
devices via an RS232 link. If this option has been ordered, the furnace or oven will be
supplied with a 9 pin ‘D’ socket for connecting to an external device. Plugging this into a
computer will allow the controller to be accessed from that computer. The computer
must have appropriate communication software installed such as Eurotherm's ‘i-Tools’.
