5.2.3 Universal Input
— Configured as Pulse Input
(Channels UI1–UI4)
Any channel UI1–UI4 can be a Pulse Input for pulse trains in the range of 0
–40 Hz.
You can accept a pulse input with any channel UI1–UI8 as follows:

On the Main Page ( Figure 13 ), click a title link from among UI1–UI8.

Under BAS Channel Configuration in the new page that appears ( Figure 21 ),
set the Channel Type to Pulse Input.
Additional fields then appear …

In the Maximum Value field, set the desired limit for the accumulated pulse
count. It defaults to the absolute maximum of 16,777,215. To reset this
value, simply write a new value in this field. You can also reset this value via
BACnet by taking the channel out of service, writing a desired value
— such
as 0 — and then putting the channel back in service to resume counting.

Set the Pull Up Resistor parameter to Enabled, if used with a passive device.
Note: The BAS Channel Type is Pulse Input, but the BACnet Object Type is
Analog Input. This is because the BACnet object is an accumulator.
