Jr X2610 Dcs Lead Help Needed

[stevehickey6]

hi all i am a bit confused with how the dcs lead conects

i have a jrx2610 transmitter and a gws rx but soon i will be getting a jr receiver as i dont think you can use the dcs facility with receivers other than jr

basicaly i aquired a dcs lead and it looks like its a jr one it has a mono plug on one end and what looks like a servo plug on the other but with only 2 wires on it

what is the difference between jr and futaba dcs leads just incase mine is a futaba and not a jr one is there any way i can tell difference also would it do any damage to anything if its the wrong one becasue i think jr or not wired like normal transmitters i know the charge lead is not


now for connecting it up if i plug the headphone plug into my transmitter it switches the transmitter on without me moving the on/off switch is this correct ?


now my main question is how does it connect to receiver ?

i have got switch going to rx and also a charge lead on it so i plug charger to charge my rx batteries do i just plug dcs lead into charge socket ?

and leave my tx battery conected to receciver and then switch tx on ?

any advise help much appreciated

thanks

not quiet sure what you are trying to achieve there. the DSC socket on the back is for a trainer / buddy box / sim lead, and i have never had to connect my 2610 to the RX to do anything. What are you trying to do,

what is the difference between jr and futaba dcs leads

JR use the mono jack plug as you've got.
Futaba used to use the 7 pin DIN type plug, but have been using a square type plug in the last few years.
You can't plug a JR lead into a Futaba socket - or vice-versa - they just won't fit.
Both leads only use two wires (they work the same) it's just the connectors that are different.

if i plug the headphone plug into my transmitter it switches the transmitter on without me moving the on/off switch is this correct ?

Yes, thats correct - on a JR transmitter.

how does it connect to receiver?

It doesn't.

i have got switch going to rx and also a charge lead on it so i plug charger to charge my rx batteries do i just plug dcs lead into charge socket ?

and leave my tx battery conected to receciver and then switch tx on ?

This sounds like a mess... not to worry...
Charging the receiver pack just involves plugging the charge source into the charge lead - which you have seen comes out of the switch harness. Thats the only thing you need to plug in to charge the receiver pack.

You can't use your Tx while it is charging.
To charge it, plug the charge lead into the charging socket (usually on the right side of the Tx near the base). Make sure you have the polatiry correct - a decent charger will warn you if it is incorrect. If you have a plug charger (basic plug in the wall and connect to Tx - trickle charger) then as long as it's the right one for that TX it will be fine... it will just take a while to charge a decent sized battery pack.

Basically, it sounds like this DSC lead you have aquired is causing some headaches - you don't need it to charge the heli or the receiver, and you don't need it to set the heli up either as thet Tx transmits it's information and the Rx receives it.
These leads are usually only for buddy boxing (connecting two Txs together) which would need two of the same ends on the cable - or for connectig to your PC to use a flight sim with your Tx - but that wouldn't use a servo plug either.
I can't say I know what this cable you have would be used for...

I thought the original use for the dsc lead was to allow you to set up the model without needing to use the power switch to turn the tx on thus avoiding any interference with other models on the same frequency. From what I understand, when the dsc is connected there is no frequency output from the radio, only the elctronic circuitry works allowing for safe setup.

thats exactly it fixxer, i havent used a JR DSC lead but with futaba rx's there is a DSC socket on the RX.

it maybe that the battery connector on the rx does this. so you could plug it in the charge lead on the switch.

have you had a dig through the manual for the tx on this?

News to me
I've only ever used the actual signal for setups!

The following is taken form my PCM9 book, I am sure the connection would be the same for other JR transmitters

DSC LEAD
The Direct Servo Connection (DSC) allows the servos to be controlled without switching the transmitter on. The lead
bypasses the RF module and allows operation of the radio equipment without the danger of interference to other models.
To use the DSC connection, plug the DSC cable into the transmitter and then into the receiver’s charge lead. The
transmitter Information Display Screen will light but no RF will be transmitted. DO NOT TURN THE TRANSMITTER
ON! Turn the receiver ON to operate the servos direct from the transmitter.
Note: The DSC function will only operate with a JRC498D Deluxe Switch harness, or the JRC498 Heavy Duty Switch
harness. These switch harnesses include the orange signal wire, as well as the brown and red power wires.

All JR transmitters that have the DSC connector operate like this.

You must have a 3 wire switch harness connected to the reciver & battery pack. What happens is that when you insert the 3.5mm mono jack into the transmitter it powers the mail electronics (but not the RF section). The signal to the RF section be it PPM or PCM is rerouted to the DSC connector. This is a 2 wire system using the brown and orange coloured wires. This hooks up to the 3 wire switch where the battery supply is fed in on the brown & red wires. The cable feeding the supply socket on the receiver now has battery +ve, battery -ve and the transmitter signal.

JR receivers have the 3rd pin on the battery port connected to internals of the reciver. It actually goes to a junction point between the RF decoder and data decoder. So you are emulating a strong received signal feeding into the data decoder to drive the servo's. What I do here is also use this same point as a monitoring point feeding to an oscilloscope so I can see the received signal.

A very useful function.
