Helix CTI-Cryogenics On-Board Cryopump Network Terminal
This type of equipment is currently made by Brooks Automation. Brooks says: "The Network Terminal is used in multiple On-Board pump installations to provide control of up to 20 pumps from a single point. The Terminal has a built-in keypad and display that allows monitoring and control of any pump on the network. The Network Terminal can be connected to a host computer through the Host RS-232 serial port so that the host can also address any pump on the network. The Network Terminal also coordinates the use of roughing valves in a specified group of pumps. This prevents cross contamination of the pumps through the roughing lines during regeneration. On-Board Pumps can be mapped together and the roughing valves in that map are controlled through a token pass protocol. The Network Terminal allows you to initiate regenerations simultaneously to two or more pumps."
