6.5 TTL I/O Operational Trigger Default Configuration
Command: "TRG <aa>", <aa> as below in Settings.
Configures the default mode of the TTL I/O ‘Operational Trigger’ (pin 2) that will control the Pumping
Program’s operation. This default setting can be overridden within a Pumping Program. (See sec. 9.1,
TTL I/O
Operational Controls
). The 2 letter configuration Setting parameter to the right of the colon (:) is defined in
column ‘Setting’ as follows:

6.7 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
