collector to another manufacturer’s pump, UV monitor, and/or chart recorder, you
need a BioFrac accessory cable (15-pin to bare wires), system cable 7 (mini-DIN to
bare wires), and 2-wire shielded cable (26 gauge or larger, available from most
electronics or hardware stores). In addition, the pump and chart recorder circuit
logic must be Start/closed circuit = ON; Stop/open circuit = OFF. The UV monitor’s
analog output must be 100 mV or 1 V. (Refer to Appendix B, Rear Panel Connector
Information (page 85), and Appendix C, Specifications (page 91), for details.)

To remotely start or stop an external pump from the BioFrac fraction
collector
1. As described in Chapter 5, Stand-Alone Operation (page 57), set the fraction
collector to Local mode. In Local mode, all fraction collection parameters are
programmed on the BioFrac device’s front panel.
2. Connect the BioFrac accessory cable (15-pin to bare wires; see Appendix B,
Rear Panel Connector Information , on page 85) to the I/O port on the back of
the fraction collector.
