Basic Hardware Operation
The following steps describe how to use the TT Series module with
hardware only. Basic application circuits that correspond to these steps are
shown in Figure 16.
1. Set the C0 and C1 lines opposite on both sides.
2. Press the PAIR button on both sides. The MODE_IND LED begins
flashing slowly to indicate that the module is searching for another
module.
3. Once the pairing is complete, the MODE_IND LED flashes quickly to
indicate that the pairing was successful.
4. The modules are now paired and ready for normal use.
5. Pressing a status line button on one module activates the
corresponding status line output on the second module.
6. 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
cc
causes the module to send an acknowledgement as soon as a
command message is received.
This is suitable for basic remote control or command systems. No
programming is necessary for basic hardware operation. The following
sections describe the functions in more detail and the Typical Applications
section shows additional example schematics for using the modules.
The Command Data Interface section describes the more advanced
features that are available with the serial interface.
