Sample Digital Pulse from Pulse Output Port at the Back Panel of the CPC
Ethernet Communication Port
Instrument status including particle concentration of the Model 3772/3771
CPC can be monitored remotely from a local area network or over the
internet using the Ethernet communication port. Ethernet communications
are described further in Chapter 7, “Computer Interfaces and Commands”.
Butanol Fill Port
Butanol is supplied from the butanol fill bottle to the instrument at the
Butanol Fill port quick connect fitting.
External Vacuum Port
By attaching an external vacuum to this port, critical flow is established
through the critical orifice described in Chapter 5. The flow through this port
contains butanol vapor so the external vacuum must be properly vented
away from work areas or use charcoal filter to absorb the butanol vapor.
Charcoal filters can be ordered through TSI (P/N 1031492 and P/N
1031493). See Chapter 8 “Maintenance and Service.”
