♦Attach the pump’s serial port to the computer’s serial port using the cable CBL-PC-PUMP-7. Attach the
RJ-11 (Telephone connector) to the pump’s “Computer” connector. Attach the DB-9 connector to the
proper connector on the computer. Note: Cable is compatible with USB to RS-232 converter cables.
♦Note on USB: If an RS-232 port is not available on your PC, the pump may be operated through a USB to
RS-232 converter cable (available as an accessory, part #CBL-USB232). This cable attaches to the
standard RS-232 to PC cable (part #CBL-PC-PUMP-7). The PC will create a virtual RS-232
communications port that communicates through the USB to RS-232 converter cable. The terminal
emulator can communicate through this virtual port.
♦Start the PUMPTERM emulator communications program. (Downloadable from web site).
♦Next the Pumping Program can be entered. Before the Pumping Program can be operated, the pump needs
the measurement of the inside diameter, in millimeters, of the syringe that will be loaded. The syringe
diameter is entered using the "DIA" command.
♦Finally, the syringe can be loaded and the pump started.
4. Loading Syringes
The syringe is loaded by securing the barrel and the pusher flange as follows:
1: Loosen the 2 thumbscrews on the syringe retainer bracket.
2: Press in fully the white drive-nut button on the pusher block, releasing the block. Taking care not to
drag the drive-nut on the drive-screw, slide the block away from the syringe holder, providing sufficient
space for the loaded syringe. Then release the white button.
3: Lift the syringe holder above the syringe holder block. Turn it 1/4 turn and then lower it onto the
syringe holder block. The syringe holder should be out of the ‘V’ slot.
4: Load the syringe with the barrel over the syringe holder and the syringe plunger towards the middle of
the pump. Place the barrel on the syringe holder, in the ‘V’ slot, with the barrel flange inserted between
the syringe holder block and syringe retainer bracket.
5: On the pusher block, turn the thumbscrew to make the slot large enough for the plunger flange. Press in
fully the white drive-nut button on the pusher block, releasing the pusher block. Then slide the block
towards the syringe plunger. Place the syringe plunger flange into the slot and against the anti-siphon
plate. When the flange is positioned in the slot, release the white drive-nut button.
6: Lift the syringe holder to slightly above the height of the syringe barrel and turn the syringe holder 1/4 turn
back to its original position and then lower it onto the syringe barrel.
7: Firmly push in the syringe retainer bracket against the syringe barrel flange and tighten the 2 thumbscrews
on the syringe retainer bracket. On the pusher block, turn the thumbscrew to tighten the plate against the
plunger flange.
⇒To unload the syringe, reverse the instructions for syringe loading.
5. Operation
Before the pump can be operated, the pumping data must be setup. At minimum, the syringe
inside diameter and a non-zero pumping rate needs to be set. The operation of the pump can
then be started from the TTL I/O connector, or from RS-232 computer control.
All data that is set will be stored in the pump’s non-volatile memory, meaning that the new
value will not be lost the next time that power is applied to the pump. The only exception is when the pumping
rate is changed while the Pumping Program is operating. In this case the new pumping rate will not be stored
in non-volatile memory.
In general, numeric data are floating point data consisting of up to 4 digits plus 1 decimal point, and is referred
to in the command descriptions as <float> data. For example 123.4, 12.3 and 12.34 are acceptable formats for
floating point data.
