Operating the KDS Allegro Peristaltic Pump System
I/O EVENT TRIGGERS
The KDS Allegro Peristaltic Pump System permits easy
connection to external I/O devices via a variety of
interfaces, including a built-in 15-pin D-sub connector.
The KDS Allegro Peristaltic Pump System software
incorporates simple commands for incorporating I/O
controls into your pump Programs. Integrated commands
for control of an external valve, multi-pump
synchronization, and general trigger signals are
integrated in the software. The following procedure
describes the use of the Advanced Options I/O
commands. Following the procedure is a description of
the selection menu options for each of the I/O command
types. Details for the electrical connection controls and
pin-out description for the 15-pin User I/O Connector are
provided in Appendix D of this manual.
The KDS Allegro Peristaltic Pump System manages trigger
events through specific pins on the I/O Connector port
on the back of the pump. The following details define pin
logic:
• Triggers are communicated via Pin 4 or Pin 5.
• Valve control signals are communicated via Pin 8.
• Pump synchronization commands are
communicated via Pin 6.
• Event signals are communicated via Pin 2.
