When defining non-default engineering units for the first time, it is recommended that the AO is
calibrated first. Engineering units can be defined after calibration is completed. Engineering units defined
on the calibration screen are automatically reflected in the Analog Output tab
calibration, refer to the RMC-100 user manual.
To change settings for the analog output after first-time calibration:
1. Select I/O System on the navigation tree.
2. Select the Analog Output tab

3. Enter the AO percentage or the engineering units number.
4. Click Send.
5. Click Re-read.

Digital input/digital output configuration

The six (6) DI/DO ports support configurable input or output modes of operation.
In input mode, the input thresholds are configurable for an input voltage range of 0 to 30 Vdc. This mode
supports signals from external devices with:
 Active voltage outputs types (non-dry contact): Digital Input (Voltage)
 Dry contact and open collector/drain output types: Digital Input (Dry-contact)
In output mode, the DO provides a MOSFET Open Drain (OD) type output capable of sinking up to 2
amps (direct current).
To configure each digital input or output:
1. Select I/O System on the navigation tree.
2. Select the Digital I/Os tab

Figure 8-4: Digital input and output configuration

3. Select the Type from the drop-down list. Digital Input (Voltage) is the default.
4. Configure each Digital I/O port as appropriate:
a. For digital input mode, select the low and high threshold voltage.
b. For digital output mode, select the current value and the initial value.
5. Click Send.

Pulse input configuration

Each pulse input has a debounce filter. Without debounce, the PI operates at a frequency range of 0 to
20 kHz. With debounce, the frequency range is 0 to 100 Hz.
To configure the pulse input:
1. Select I/O System on the navigation tree.
2. Select the Pulse Inputs tab
