5.8 Resuming When Paused
If the Pumping Program is stopped before the completion of the Pumping Program, the response prompt will
change to 'P', indicating that the Pumping Program is paused. While paused, starting the pump again will
resume the Pumping Program where it was stopped. This means that the Pumping Program will continue at the
point in the Phase where it was stopped and the ‘Volume to be Dispensed’ will still be referenced from when
the Program Phase first started.
Pause is exited by sending a stop command "STP", or changing any setting. When the Pumping Program is
started again, it will start from the beginning (Phase 1).
5.9 Pump Stalled
When the operation of the motor is impeded due to excessive force needed to drive the syringe, the pump will
stop, pausing the Pumping Program, and a stall alarm will occur.
The buzzer will sound continuously if alarms are enabled. Also, if the RS-232 Safe Mode is enabled, an auto-
alarm message will be sent to an attached computer.
Sending any command will stop the buzzer and clear the alarm. When the problem causing the pump motor to
stall has been corrected, the Pumping Program can be resumed from any start trigger source: TTL input, or RS-
232.
6. Setup Configuration
The following configuration parameters can be set or queried:
The values for "n" are "0" for off, "1" for on. See relevant sections for command definitions.
Command Description
ADR nn Set the pump network address or mode of communications.
PF n Power Failure mode, where ‘n’ is the current setting.
LN n Low noise mode to minimize the motor’s micro-stepping resonance
AL n Alarm mode, where ‘n’ is the current setting.
TRG aa Operational Trigger default configuration, where ‘aa’ is the current configuration.
DIN n Directional control TTL logic input setup
ROM n Pump motor operating TTL logic output configuration
LOC n Lock out mode. Sets Auto-Run mode with Sub-Programs
6.1 RS-232 Pump Network Configuration
Command: ADR [ <nn> | <RECP> | <DUAL> ]
The pump can be configured to communicate either with a computer or another pump. Communications with a
computer (Address Mode) is the default setting and will be indicated by setting an address from 0 to 99.
When in the default Address Mode, up to 100 pumps can be attached to a computer in a single pump network.
The network address is defined by the 2 digits to the parameter <nn>. If only one pump is attached to the
computer, set the network address to 0 (ADR 0), which is the factory default.
Additionally, the baud rate can be set with this command. For details see the detailed RS-232 command
section.
