RS485 serial output with FXB protocol
Instruments with the RS485 FXB communication option use industry-
standard FXB protocol. Refer to the company website for FXB protocol
information.
Pulse communication
Instruments with the pulse communication option send an 8-µs pulse
signal when a particle is detected. Refer to
counter or data acquisition system receives the pulse signal and counts
the pulses as particles.
Instruments with pulse communication have two pulse output channels
(Ch 1 and Ch 2). Channel 1 sends a pulse signal when the Channel
1 particle size is detected. Channel 2 sends a pulse signal when the
channel size that is selected by the user is detected.
Pulse communication includes a status output signal that goes from low
to high when there is an active alarm. Pulse communication cannot be
used in a network configuration.
Set the network address for pulse communication instruments to 1.
Refer to
Table 6
on page 17.
The pulse signal can be sent in one of two count modes:
• Differential mode (default)—A signal is sent on Channel 1 when a
particle is between the first and the second channel size thresholds. A
signal is sent on the Channel 2 when a particle is larger than the user-
selected channel size threshold.
