BB9 Communications Box
for Multiple Apex Devices

The Apex Vacuum Pressure Controllers can be used in conjunction with the Apex Mass Flow Controllers and Meters. Communication input/output can be user specified with the choices being 0-5V, 0-10V, or RS-232(provided on all Pressure Controllers). The BB9 Communications Box allows other Apex Vacuum Devices such as Apex Mass Flow Controllers to be used in conjunction with Apex Pressure Controllers.

FlowVisionSC software can be used to control Apex Devices with computer control communications.

The Apex Vacuum Pressure Controller has a user display to change gases, set the pressure and display readings. The RS 232 interface allows control of 26 individual controllers or meters off one computer RS 232 port.
