10.14 Serial printer protocol
The Serial printer protocol is used to connect the pCO to any printer fitted with an RS232 interface; this allows paper copies to be generated of particularly important
information, for example the trend in the temperature in a cold room over time. The information to be printed can be completely configured in the application.
Instead of the printer, other devices with RS232 serial interface can be connected, for example a terminal emulator or a PC with a program that saves the data received
via the serial link to the hard disk.
Available on the following serial ports
