Using the Snap-In with Renard-Plus controllers
1. Somewhere near the data input RJ45 jacks is a 5-pin
header, aptly named RenW Header, JP1, such as the
example to the right.
2. With a 1x5 female header installed on the BOTTOM of
the adapter's PCB, simply plug the adapter into the
RenW header.
3. Note that no modifications need to be done to the
adapter's PCB at all,
4. Note also that you should not install the 1x4 stackable
headers on the adapter and you do not need the 3.3
Zener diode or the XMIT header pins or shunt jumper.
5. The L78L33 regulator can be used with an XBee radio,
but the higher-capacity UA78M33 regulator is required
if you plan to use the ESP8266 module in place of an XBee.
6. If you plan to mount the adapter OFF the Renard-Plus controller instead of mounting it
directly onto the RenW header, use a 5-pin connection cable of suitable length to connect
pins 1-5 of the adapter to their corresponding pins on the RenW header.
Using the Snap-In with other controllers, Renard or otherwise
The adapter's pin-out is highlighted in the picture to the right. Some comments:
Install the UA78M33 voltage regulator. Do not use the
L78L33 regulator.
Do not install the 1x4 stackable headers -- you won't need
them and quite likely, the chip in the controller is not pin-
for-pin compatible with what the snap-in needs.
If using the ESP8266 module, you do not need the 3.3
Zener diode, the 2-pin jumper and jumper shunt.
If using an XBee radio but you will not be transmitting
from the adapter, you do not need the 3.3 Zener diode, the
2-pin jumper and jumper shunt, either.
The data output from the adapter is at pin 5, TX data. This
is a +3.3v TTL output that should be connected to the
controller's data input. It is TTL, not RS232 or RS485 so
you likely should connected it to the controller AFTER the
controller's normal data input circuitry.
Connect the adapter's pin 3 Ground to the controller's DC ground.
Connect the adapter's pin 1 +5vdc to +vdc somewhere on the controller. Note that while the
UA78M33 regulator is tolerant of voltages up to 30vdc and the LM1117T is tolerant up to
20vdc, the adapter generally does not need a heat sink to dissipate heat caused by high
voltage inputs and therefore, try to find a +5vdc connection. (Note: If the controller has only
