Start Trigger: The Pumping Program may be started, or stopped, from multiple sources.
These are the TTL I/O ‘Operational Trigger’ input, or from a command
received through the RS-232 connection.
3. Setup
 Place the pump on a stable surface.
 Plug the connector end of the power supply into the power plug located on the PCB on the side of the
pump. See section 9, Logic Interface: TTL Input and Output, for a diagram of the connectors on the
pump. After power is applied to the pump, the buzzer will beep.
 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 syringes are loaded by securing the barrel and the pusher flanges as follows:
1: Loosen the 2 thumbscrews on the syringe retainer bracket.
2: Turn the Drive Release Knob ¼ turn clock-wise, then lift. 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. While lifting the the knob, press on the middle of the side for easiest movement.
3: Lift the syringe clamps above the syringe holder bracket and turn 1/4 turn and then lower onto the
syringe holder bracket. The syringe clamp should be away from the ‘V’ slot.
4: Load each syringe with the barrel over the syringe holder bracket and the syringe plunger towards the
middle of the pump. Place the barrel on the syringe holder bracket, in the ‘V’ slot, with the barrel flange
inserted between the syringe holder bracket and syringe retainer bracket.
5: On the pusher block, turn the thumbscrew to make the slot large enough for the plunger flange. Adjust
the pusher block position as needed towards the syringe plunger. Place each syringe plunger flange into a
slot and against the anti-siphon plate.
6: Lock the pusher block in place by turning the release knob couinter-clockwise until secure.
7: For each syringe, lift the syringe clamp 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.
8: Firmly push in the syringe retainer bracket against the syringe barrel flanges and tighten the 2 thumbscrews
on the syringe retainer bracket. On the pusher block, turn the thumbscrews to tighten the plates against the
plunger flanges.
 To unload the syringe, reverse the instructions for syringe loading.
