Typical Applications
The following steps describe how to use the HumPRC
with hardware only.
1. Set the C0 and C1 lines opposite on both sides.
2. Press and hold the PB button for 30s on the unit chosen as
Administrator. When MODE_IND flashes, release PB. The unit is set
as the Administrator.
3. Press the PB button on both sides. The MODE_IND LED begins
flashing slowly to indicate that the module is searching for another
module.
4. Once the pairing is complete, the MODE_IND LED flashes quickly to
indicate that the pairing was successful.
5. The modules are now paired and ready for normal use.
6. Pressing a status line button on one module (the IU) activates the
corresponding status line output on the second module (the RU).
7. Taking the ACK_EN line high on the RU causes the module to send an
acknowledgement to the IU. The ACK_OUT line on the IU goes high to
indicate that the acknowledgement has been received. Tying the line
to V causes the module to send an acknowledgement as soon as a
cc
command message is received.
This is suitable for basic remote control or command systems. No
programming is necessary for basic hardware operation.
Basic application circuits for one-way remote control are shown in Figure
84. Circuits for bi-directional remote control are shown in Figure 85.
