Micron Tx22v2 Operation manual

Tx22v2 Transmitter
User Information
Tx22v2 is a hand-held wireless transmitter intended to control up to 12 model railway trains. It
has controls for Speed, Direction, Inertia, Li hts and Loco selection. Tx22v2 is available in 2
versions: with and without a detent on the throttle control:
•the detent version has a mechanical 'click' at the centre of the travel and is intended
for use with DT receivers confi ured for fwd/rev control on the throttle channel,
•the no-detent version is for use with receivers confi ured for full-ran e throttle and
separate direction switch. When the Tx22v2 to le switch is not used for direction, it
is available for controllin auxiliary functions such as LED li hts and sound modules.
Technology
•Tx22v2 uses the 2.4GHz band which requires no frequency channel control and is very resilient a ainst interference.
All radio frequency components are contained on the internal Tx2 module. There are no user adjustable parts on this
module and it should not be modified.
•Tx22v2 is compatible with all DSM2 receivers. This includes all Deltan receivers.
•Any number of receivers can be bound to your Tx22v2 but only up to twelve, bound to different Selecta positions,
should normally be switched on at a time to operate them independently. An exception to this rule is multi-headed
trains – Deltan receivers support features (which required pro rammin setup) to match the speed of separate locos
in a multi-headed consist.
•Ran e is suitable for indoors and small outdoor sites; the outdoor free-air ran e to a Deltan receiver is at least 50m.
Ran e indoors is affected by buildin construction materials, furniture, people and receiver installation.
•Knob and switch positions are transmitted as separate 'channels' (1-7) which must match the receiver confi uration:
throttle: channel 1
selecta: channel 2
to le switch: channel 3 (up or forward = channel hi h, down or reverse= channel low)
inertia: internal use or channel 4 or channel 5 (confi urable)
bind button: channel 5 (none if inertia confi ured as channel 5) (up = channel hi h, down = channel low)
Battery
•Tx22v2 uses a PP3 9V battery, Alkaline, LiIon or NiMH The maximum
workin volta e of the internal Tx2 module is 10V and there is a protection
diode wired in series with the battery ne ative lead. This allows the battery
volta e to be up to 10.7V. If the battery volta e is above this value, the
internal re ulator will shut down and the transmitter will not operate.
•Remove the slidin lid at the bottom rear of the case to insert or replace the
battery. The ima e shows the orientation. The battery is held in place with a
piece of foam tape attached to the battery compartment lid.
•Make sure that the power on/off button is off (up) before) addin or removin
a battery.
•The connector will only clip onto the battery one way. TAKE CARE, if force is needed, the connector is probably the
wron way round.
On / Off Push Button
•Tx22v2 has an illuminated push-button on/off switch. It is best to switch the transmitter on before the receiver.
•The LED flickers sli htly while an Inertia transition is in pro ress.
•The LED flashes more boldly when Bindin .

Speed / Throttle Kno
•300° rotary control with 'centre click' (optionally available with no click)
•Full rotation is either 'low off' 0-100% motor control or 'centre off' (depends on receiver setup).
◦Use the pro ram 1, 1, 2, 1, 3 to confi ure a Deltan receiver for full ran e throttle on channel 1 and direction
control on channel 3 (the Tx22v2 to le switch)
•The Throttle knob controls transmitter channel 1 and channel 6.
Direction Switch
•The Direction switch is used to select forward/reverse with receivers that have 'low off' motor control.
•The switch can control li hts instead of direction with receivers that have 'centre off' motor control.
•The switch has a centre off position which is not used for Direction control, but useful when controllin li hts.
•The Direction switch controls transmitter channel 3.
Inertia / Momentum / Brake Kno
•Inertia 'dampens' or slows down chan es to Throttle (channel 1 and channel 6).
•The Throttle knob sets a 'tar et' and Inertia chan es throttle slowly until it reaches that tar et. The LED flickers while
a chan e is in pro ress.
•To stop quickly Throttle and Inertia must be in the 'off' position. Inertia is off when turned fully to the left.
Selecta
•This is a 12-way rotary switch with positions matchin those of a clock.
•Allows 12 locos to brou ht in and out of service without touchin them (requires Selecta enabled receivers e :
Rx41d-22-v5, Rx6x-22 and Rx102). Receivers have a short delay when bein brou ht into or out of control, this to
avoid transient selection as the Selecta knob is moved; do not move any controls for 1-2 seconds after chan in the
Selecta switch position.
•The Selecta knob controls channel 2.
Bind Button
If a receiver has not previously been bound, it has to be 'paired' with the transmitter. Bindin is only required once per receiver.
1. Choose the Tx22v2 Selecta switch position for the loco but don’t switch the Tx22v2 on yet.
2. Put your receiver into Bind mode (if a Deltan receiver, switch it on and wait 20s for the LED to flash fast).
3. Press and hold the Bind push-button.
4. Switch the Tx22v2 on by pushin the Power button and then release the Bind button, the power LED will flash.
5. Bindin is complete when the receiver LED stops flashin .
Once the transmitter is switched on, the Bind button, if pressed for less than 20s, acts as a simple switch controllin transmit
channel 5. If the Bind button is pressed for more than 20s, it alters how the Inertia knob is used:
•if the Bind button is pressed for 20s or more within the first 60s of switchin on, it will perform calibration of the
throttle knob centre position
•if the Bind button is pressed for 20s or more after the first 60s of switchin on, it will to le what the Inertia pot is
used for – Inertia or control of channel 5.
The default behaviour of the Inertia knob is to control throttle / brake inertia as described above. To to le the Inertia knob
function:
1. switch the Tx on and wait 90s without touchin the Bind button
2. press and hold the Bind button
3. after 20s the power LED will o off for 2s and then come on for 3s; release the Bind button in this 3s to toggle the
Inertia knob between controllin Inertia or controllin channel 4.
4. after a total of 25s (i.e. after the 3s of LED on) the power LED will o off and stay off until you release the Bind
button; this causes the Inertia knob to control channel 5

5. repeat steps 1 to 3 to revert to the Inertia knob controllin throttle inertia.
•If the Inertia knob is bein used for Inertia or channel 4, the Bind button controls channel 5 if pressed for less than 20s
•If the Inertia knob is bein used for channel 5, the Bind button has no effect on channel 5 but is still used for bindin
and to lin what the Inertia pot is used for.
Receiver Programming with Tx22v2
Deltan receivers may be pro rammed usin Tx22v2. The receivers have a rich set of functionality which is not possible to
describe here, refer to the Deltan web site at www.deltan .co.uk for details on pro rammin sequences for a specific receiver.
Please contact Micron if this table looks too dauntin and we will send you specific pro rammin instructions for the function
you want to chan e.
The receiver must first be put into pro rammin mode and then the Tx22v2 to le switch is used to enter a pro rammin
sequence. There are 2 methods of ettin a receiver into pro rammin mode:
1. place the controls for R/C channels 2 and 4 at the extreme positions and then switch receiver on, or
2. switch receiver on and enter the morse code SOS usin the bind button (R/C channel 5)
Method 1 works for all Deltan receivers, method 2 works only for Rx6 types and Rx47.
Method 1 (chan 2 and 4)
1. switch Tx22v2 on, receiver off
2. set the Inertia knob to control channel 4 (described above).
3. rotate the channel 2 (Selecta) and channel 4 (Inertia) knobs fully left or ri ht (not centred).
4. centre the channel 3 (Direction) to le switch.
5. put channel 1 (Throttle) in the 'off' position.
6. switch the receiver on.
7. the receiver LED will flash rapidly
8. centre the Selecta and Inertia knobs
9. the receiver LED will flash once, pause and repeat
Method 2 (SOS)
1. switch the Tx22v2 on and then the receiver, receiver LED must be lit
2. centre the to le switch
3. wait at least 5 seconds without touchin any transmitter control
4. tap out the morse SOS (... --- …) on the bind button where:
◦a dot is a short press of less than 0.7 second
◦a dash is a lon press of about 2 seconds
◦pauses between dots or dashes is about 1 second
5. if the SOS is accepted, the receiver LED will flash once, pause and repeat
6. if the SOS was not accepted o back to step 3
To enter a receiver program sequence
The Tx22v2 to le switch is used to enter the value for each level of the sequence, the receiver LED flashes to show the di it
value. For example, the sequence to set Rx60 output P3 to on/off latchin and operated by the bind button is 3 3 2 5 1.
Decodin this sequence ives:
Level Value Explanation
1 3 Pro rammin table menu 3
2 3 Rx60 output P3
3 2 on/off latchin
4 5 channel 5 = bind button

5 1 start at 0V, to le between 0V and 3.3V each time the bind button is pressed (channel 5 oes
low)
As each pro rammin level is entered, the receiver flashes to show the value, pauses and then repeats the flash count. The
initial 1-flash after enterin pro rammin mode is for menu 1 which is the motor speed control.
•press the to le switch down (position B) and back to centre to increment the number of LED flashes for the current
pro ram level
◦each level has a maximum value, the flash count wraps to 1
◦if the current flash count is 4 and you need 2, you have to increment to the max, increment a ain to et to 1 and
then a ain to et to 2
•press the to le switch up (position A) and back to centre to save the LED flash count for the current level and move
on to the next pro ram level
◦when all pro rammin levels have been entered, the receiver LED will li ht solid and the receiver will exit
pro rammin mode
The receiver LED will flash rapidly as the to le switch is pressed down or up and will return to slow flashin (or solid if at
the end of a sequence) when the to le switch is returned to centre.
If at any point in the sequence, you think you have made a mistake – switch the receiver off and start a ain.
To enter multiple pro rammin sequences, each one requires the receiver to first be put into pro rammin mode.
