Help with Airwire G2 Motor drives

Electronics
#1

Hello all! I’ve been mounting a battery operated Airwire G2 and a Phoenix sound bd. 2K2. For testing on the bench I’ve connected my transformer directly to the G2 and with the NCE transmitter I am able to get sound/bell/whistle to work. However the motors do not operate. I used an ohm/volt meter to measure across Tm3-pins 2 to4 and pins 3 to 5 and do not see any voltage to speak of when I increase the speed from the throttle. Should I see voltage here? Is there a CV somewhere that is not set properly?

thnks in advance

Airwire to be bench tested has to have a motor attached to it. It will not put out voltage until there is a need for it.
You can use any motor block from a loco.
Or put the loco up on rollers.

Oh yeah, you will have to assign a loco number with the throttle.
Ooops: read your thread wrong.
Dunno about any other transmitter except the Airwire.

I did not know that there recievers will work with other throttles, as there throttle is specific to these boards, and last i knew would not operate other dcc products, as there easy dcc uses a simular but different throttle.

Walter,
Since your 2K2 is responding to your transmitter, the receiver has to be on the same frequency as the transmitter. If you have not changed any addresses, the 2K2 & the G-2 should respond to DCC address 03. It is possible to have the 2K2 and the G-2 assigned to different addresses. Make sure that both units are set to the same address by re-programming the addresses.

I have measured the motor output on AirWire receivers and there is voltage on the output terminals when I turn up the speed control.

Bill,

Thanks to all for input. I did not realize that the 2K2 is programmed with an address. I thought that the Airwire receiver was responsible for the channel and address and only passed DCC commands sound commands to the 2K2. Anyhow, I did program a long address with the G-Wire transmitter and the sound board responds only when I have this engine selected but still no motor movement. When you said you measured the Airwire recievers for voltage, did you have a motor connected? Is there any way that I can verify that the Airwire reciever has accepted the long address? Do you know how to set the Airwire back to factory defaults.

thnks in advance
walt

When you program the address, the 2K2 and the AirWire should both chirp twice. I did not have a motor connected. To reset the receiver, please refer to page 19 in the AirWire G-2 manual. If you don’t have the manual, refer to the CVPUSA.COM website for documentation.

So what I’ve learned is 1) do not set the address to 0 because the 2k2 stops responding to DCC commands. I had to use the Phoenix programmer to reset the address of the 2k2 to gain control over it via the radio. 2) I don’t know why I could not get motor voltage in the beginning but after reseting the 2k2 and doing an NCE reset I now have motor control. I may also have done something else while I was pressing buttons but I don’t know at this point what cured it. Also measuring across the motor terminals of the G2 without the motors connected does exhibit voltage with an increase or decrease of the speed dial.

thnks to all
