Note
When the system is in Dispense Mode, all gradient modes,
constant pressure mode, and auto-refill, as well as serial con-
trol, are unavailable until Dispense Mode is turned off.
The pump can be externally controlled for pressure or flow rate
operation with an analog voltage or through the serial interface.
The serial interface allows you to control the pump operation
from an IBM-PC or compatible computer that has an RS-232-C
serial output. The serial interface accepts English command
words from the computer, like constant pressure, refill, etc. For
more information see Section 8
The syringe pump can be controlled externally by analog voltage
in either constant flow or constant pressure mode. The input
range is 0 – 11.5 volts (for all pumps), with a resolution of 5000
increments per volt.
Note
The input range for the 4-20ma option is set to 4-20ma
Two wires are required for analog control. The analog common or
ground wire should be connected to the GND terminal under
ANALOG INPUT of the ACCESSORY connector on the con-
troller rear panel. The analog control or input wire should be con-
nected to terminal 1 under ANALOG INPUT.
If two pumps are used with the controller, the second analog
control or input wire should be connected to terminal 2 under
ANALOG INPUT. If three pumps are used with the controller,
the third analog control or input wire should be connected to ter-
minal 3 under ANALOG INPUT.
If four pumps are used with the controller, the fourth analog
control or input wire should be connected to terminal 4 under
ANALOG INPUT.
When using one of the multi-pump operation modes, only the
ANALOG INPUT terminal 1 needs to be connected to control the
A-B pump pair and ANALOG INPUT terminal 3 needs to be con-
nected to control the C-D pair.
Note
For the 4-20ma input option the negative output wire connects
to DIGITAL GROUND. The positive output wire connects to
ANALOG INPUT 1-4.
