all the environmental parameter can be monitored and controlled from the console. instructions are typed in by means of a ASCII type keyboard. The console is really a datalogging computer that includes an intel 80c188 processer. The data generated can either be stored tempararly in the ram memory of the system (1Mbytes) or stored permanently in a hard disk, or unloaded through a RS-C port at a very high speed-up to 115,200 bps. The system is powered by four-12V batteries that supply 4-8 hours of operation. Additional sensors can be plugged to the console computer. For doing that, both analog and digital input/output channels are available. Measured and calculated variables, such as photosynthesis rate, conductance and internal co2 concentrations are displayed in real time.
