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.
