The binding function stores the TX signal unique ID code and PPM frame rate and number of servoes into the receiver
this must be done every time the number of servos is changed on the RC unit. (or another RC system is used with this system)
1 power off, tx and rx.
2 hold down bind button on TX
3 powerup the TX, (we assume right plane memory is recalled on your RC unit)
4 remove finger from the bind button :-)
5 power up receiver, make sure both antennas are connected and within 20meter distance
5 wait 1-2 sec, see the RX LEDs go from lit into fast blink mode
6 power off tx (rx is still on)
7 power on tx (rx is still on)
8 test all servo functions on plane works and have ultra fast and smooth responce
9 with TX on, try to power OFF, and ON the rx and prove it lock to the tx very fast after power on.
http://www.vimeo.com/3794162 Instruction video how to bind and store failsafe.
if you use EXTERNAL BATTERY for the LRS TX box, then the binding procedure is a little bit different
leave the RC unit on ALL the time and connected to the LRS TX box,
the power on off to the TX as mentioned in the binding procedure is ONLY the LRS TX box.
now it will work, the binding mode is only activated when button is held down WHILE power to the LRS TX go on
The receiver can store all known good servo positions for failsafe
they will be recalled automatic in case loss of radio link happens
it is strongly recommended to perform a failsafe storing after each binding
To store failsafe:
during normal operation or even flight, press and hold the button on tx for at least 1 sec
the RX will blink the leds it is not recommended to hold the button for many sec.
while setting up a plane it is often needed to add or remove RC channels, this will offcource change the PPM
repeat time, so a new binding will be needed, if ignored servo update speed will be slow and a bit jumpy,
but you will still have controll of your plane, it is advised to only setup a plane while grounded !
The PPM input signal must have a constant frame repeat time,
servo signals from 4-12 can be transferedr, if PPM signal have under 4ch it will be refused.
The behaviour of the Rx in case of an interference/failsafe:
In case of a bad data pakage the last good will be kept and an error counter incremented,
when a good pakage is received the servo positions will be updated, and error counter zeroed,
If error counter > the max alllowed 45, it will recall the stored failsafe settings.
Failsafe will be activated if TX is turned off, or if out of range/gets bads for 1 sec, (22mS x 45 = 1sec)
it will resume to normal if signal comes back.
Servo outputs are programmable in the case of a failsafe just like a conventional PCM RX. (read about failsafe)
Diversity is incorporated with an antenna switch, after the two seperate LNA low noise amplifiers,
the RX will check both antennas for best signal in case signals levels get below a certan level
at strong signal levels the antenna switcher is disabled
NEW FEATURES ADDED IN THIS VERSION
RX only output servo signals when binded and locked, NEW in 308
RX have no more blocking problems when used close to a tx or even a 7 w booster
serial out of rx with good/bad information
(9k6 8N1 ascii letters = bad frequency number, if no bytes out, all pakages are good on all frequencies)
ppm out of rx (remove R5 solder wire to the right pad)
more servo channels, now 4-12 (if 12 the ppm out is auto disabled and ch12 is on that pad)
to get access to servoes over 8 and ppm out, expert soldering is needed (for now)
servo ch9 pin 26, ch10 pin 27, ch11 pin 28
more FHSS frequency hopper, now super imune to noise.
more systems will work at same field,
each tx unit have unique serial code used for binding and hopping system
new binding methode, free one hand
new store failsafe, can even be done while flying
double servo resolution on first 8 servoes, before 255 steps, now 512 steps
ch9-ch12 have 255 steps.
diversity system changed a bit, so rx should also handle super strong signals and not block
if you have performed a software upgrade to version 307 on RX with 3.00 or 3.10 as the hardware number,
you must remove R5 before flight, the resistor is placed about 12 mm left of ch2 servo connector.
all the tweaks for RX board 3.00/3.10 with software 307
