APPENDIX B

CONNECTION TO OTHER INSTRUMENTS

The I/O connector on the rear panel of the pump is for the operation

of the fraction collectors and chart recorder (see Figure 3-2). Output

signals are TTL compatible. To use these signals for non-Bio-Rad

devices, you must insure that the circuit external to the Econo

Gradient Pump does not draw more than 15 milliamperes of current.

The following table describes the rear panel mini-DIN connector

pinouts for this I/O connector.
