4.5 Messages from the ULE Controller to the ULE Node

To send a message from the Controller to the Node:

1) Press the Tx Request button on upper left in HAN Window of Controller GUI. You should

observe Link Status as "Requesting".

2) Now you need to wake up the ULE Node and have it respond to this Link Request by

triggering an event from the VAR simulator (eg Keep Alive, Tamper, Alert). You will see the

Link Status on the ULE Controller change to "In Link". The ULE Node is now available for

an incoming message from the Controller

3) Let's pretend that the ULE Node is an AC Outlet and send it an ON command from the

Controller GUI, HAN Window (Lower Left as shown below)

4) Now check the VAR Log window and you will notice the report of an incoming ON message:

The ULE Node has several options (configurable via EEPROM) for entering and exiting hibernation.

The Node in your Starter Kit has been configured to enter hibernation upon command from the MCU

(the SLEEP message in the VAR window) and exit via the Wakeup button (AMP_OUT2 from the

DHAN) on the DHX91 EVB (see the photo in the earlier section). Let's try it!

a) Prior to entering Sleep/Hibernate you see ~28mA on your Node Power Supply

b) Generate and Send the Sleep Command

c) You should drop down to ~4µA

d) Now hit the Wakeup Button and note the return to 28mA!
