6.4 TTL I/O Directional Control Input Configuration
Command: "DIN <n>"
Configures how the TTL input ‘Pumping Direction’ (pin 3) will control the pumping direction. (See sec.
9.1, TTL I/O Operational Controls).
Setting Mode Function
0 Reciprocating Pumps Falling edge: Infuse; Rising edge: Withdraw
- Used for 2 pumps operating in opposite directions
1 Dual Pump Falling edge: Withdraw; Rising edge: Infuse
- Used with 2 pumps operating in the same direction
6.5 Pump Motor Operating TTL Output Configuration
Command: "ROM <n>"
Configures the functionality of the 'Pump Motor Operating' TTL output pin (TTL pin 7).
Setting
<n> Mode
0
Sets the output to logic high only when the motor is operating (pumping).
Sets the output to logic low when the motor is not operating or when the Pumping Program is executing
a pause timer or is stopped
1 Sets the output to logic high when the motor is operating (pumping) or when the Pumping Program is
executing a pause timer.
Sets the output to logic low when the Pumping Program is stopped
7. Pumping Program
A Pumping Program is simply a pre-defined sequence of actions, or functions, which guarantees consistent
and precise operation of the pump, automatically and with or without any user intervention. A Pumping
Program can be as simple as continuous pumping at a fixed infusion rate. Or a Pumping Programs could
consist of a pumping rate and direction of pumping for a specified volume, then switch to another pumping
rate. Also a Program can interact with external devices through the TTL I/O connector, make decisions, or
stop pumping for a period of time.
Programs are broken into individual operations called Phases. Each Phase consists of a function that can
be a control function or pumping function. A pumping function, such as ‘RATE’, consists of a pumping
rate, optional “Volume to be Dispensed”, and the pumping direction.
Complex dispensing systems can be designed, involving multiple liquids, each dispensed from a different
pump, plus other equipment and sensors. Pumping Programs can be designed for each pump which enable
multiple pumps to synchronize with each other, and the other equipment and sensors, using a cable
connected to the TTL I/O connectors of each pump.
When the Pumping Program is started, either from the keypad, TTL I/O connector, or from RS-232, the
Pumping Program will begin with Phase 1 of the Program. After the completion of each Phase, the pump
