CM (Computer Monitor) commands are used for monitoring pump
information. The Return Record Format section gives details of
parameters and return information. The pump shall respond, when
queried, to the following “CM” or monitor-only commands:
CM (Monitor)
Command Code Name
A Alarm/Status Request
D Infusion Data Request
G Time and Date Request
I CI Commands Enable
M Pump Model Number Request
Y Pump Serial Number Request
CI (Computer Interface) commands initiate action by the pump and
must be preceded by the CM “I” command, placing the pump into CI
mode.
Entry to CI Mode :
Like other CM commands, the pump responds to the “I” command even
when powered down on AC. Receipt of an “I” command will enable CI
mode when the following conditions are met. If these conditions are
not met, the return code in the return record will be set to ‘Invalid
Mode’ and no command data will be returned as part of the response.
•
The pump is in Primary mode. This excludes Secondary, Rate
Taper, and Dosing modes.
• The default Primary mode screen is displayed. This Primary mode
default screen text is “XXXXX mL this infusion”.
•
No Rate or VTBI entry is in process.
• The pump is not in Run Mode.
When not in CI mode, the pump will respond to any CI command by
indicating ‘invalid mode’ in the ‘return code field.’ This signifies that
the command is not supported for the current pump state. See the “I”
command’s entry in Table I for further details.
Any manual key press while powered on an unlocked key will cause
the pump to terminate CI mode. See the command 'Keypad Lockout
Setup' in Table I for further details on locked/unlocked keys.
