I’m back again.
Well, i did a test as per your last suggestion.
Allow me to recap about what i have understood and what i have done accordingly.
I have mounted a RJ-45 Plug termination (dongle) with the pin 1 & 3 linked with a resistor (51k) and pin 2 & 6 with another resistor (51k) and the rest of the pins are not connected means cut off. as shown in the diagram below, that dongle is then connected to the PIDU port of the cnPulse only. Is that correct?
A patch cable is then connected between the ODU port of the cnPulse and the PTP670 AUX port.
Hence, from the PTP670 from the TDD Synchronization field i have set the followings;
- TDD Sync Device = Cambium Sync Injector
- Sync Input Port is = AUX
- Sync Output = None (Aux can’t be selected at this stage)
Unfortunately the test was not successful and i believe technically that there is something wrong.
If we look at it and as per my understanding of the cnPulse, this device could do the following;
- PIDU Port - Power input
- ODU Port/Sync - Could power up and provide sync to a PTP/PMP radio.
- AUX Port - Could provide sync to a PTP/PMP radio (AUX to AUX)
If we go back to what you’ve requested to perform is to connect the cnPulse ODU port (which is basically an output port) to the AUX port (which is also an output port for PoE) of the PTP670. Therefore, there are 2 output ports connected.
My question for the dongle is, should the rest of the pins (4,5 7,8 which is for power) connect somewhere? As this part of the circuit open.
I did not see where i could enable the PoE output from the PTP670 neither.
Kindly advise accordingly the way forward.
Thanks again for the support.
