Connecting Commubox FXA195 (USB)
The Commubox FXA195 connects intrinsically safe transmitters with the HART protocol to a
computer's USB port. This allows remote operation of the transmitter using Endress+Hauser's
FieldCare operating program. Power is supplied to the Commubox through the USB port. The
Commubox is also suitable for connection to intrinsically safe circuits. A communication resistor
(250 ), which can be switched on and off, is integrated in the Commubox FXA195. See
Technical Information TI237F for further information.
