Command Syntax:
- Communication command is terminated with .
- Communication return starts with and is terminated with .
Command float formatting:
The device requires strict formatting on its floats. The output value must fit 5 characters and be within the range 9999. to .9999.
Multiple pumps can be daisy chained together and controlled via a single IOC. Each pump has an address which can be set using the ID:SP record. By default (and in a single pump configuration) this is 00.
A given pump can have it's own unique address defined. So two pumps might not have the same address. Typically pumps are labeled with a sticker 00, 01 etc. that will indicate this. If you ever need to change this the pump has an method that will allow you to define this (refer to the manuals section on the ADR method).
The device has it's own logic for setting the units of volume to be pumped VOLUME:UNITS based on the diameter of the syringe installed in the pump DIAMETER. In testing it was found that: Diameter <= 14.00mm - uL, Diameter > 14.00mm = mL. A small warning about this has been placed on the OPI to inform users.
The units for the rate can be selected but will only be set when setting the RATE:SP. You can resend the same set point to set newly selected rate units.
