Temperature sensor with display connectivity

DCIM_Support · ‎2020-07-02

Hi All!

I have an issue with AP9520TH sensors connected to Netbotz 200.

There are three sensors and sensor pod 150 on A-Link bus, each configured with it's own address and at sensor page I can see only one of them. If I swap sensors, I can see another one, but only nearest to appliance in the chain and have message about previous sensor disconnecting.

Sensors are "new" type, with 2.1.4 firmware.

I assume that it is a cabling problem and try to replace all cables tomorrow, but maybe there is another reason?

Did you have similar issue?

Hi Valentin,

I have seen where customer may hold the unit up-side-down when configuring the dip switches. Please be sure when looking at them and when matching them up with the manual, make sure the APC sticker is facing up. Make sure they're numbered differently. Other than that, please make sure you are using CAT-5/CAT-5E cables. If you are using CAT-6, you're likely to have comm issues. If you also have sensor pod 150s connected, try removing them for testing purposes. If you have too many things on the A-link buss, you may need to power 1 of the 150s (if exist). You may also want to terminate the string. The 200 should have come with a terminator, I suggest tryong both with and without the terminator in the last sensor.

It was a cabling issue. After replacing cables with new ones CAT-5, system works as expected.
