It's not possible to add radios to RM without knowing the serial number.
[Q] Our dams early warning system are connected using IP Site Connect MOTOTRBO radios and repeaters. We have over 600 DGM radios connected by 20 repeaters, covering a very wide area.
I've been working with Motorola guys [...] in order to implement NAI and MNIS to perform radios configuration via OTAP.
The issue is, we haven't cataloged our radios Serial Number so far, and doing that manually (over USB connection) would be a huge effort in terms of time spent.
I have watched most of your content on Youtube and I wonder if is there a way to solve this (whether getting the SN remotely via RM/SmartPTT/other application or being able to connect to a radio even without its SN).
What i tried to do was adding a generic SN (e.g. 511NTX0000 for DGM5000e series) and providing the correct the Radio ID. Although there was indeed data traffic between RM and the radio, I got the error "#10002 - Task SN doesn't match device SN" and couldn't go further on it.
Is there anything I can do?
[A] It is only possible to add and write a radio or repeater to MOTOTRBO Radio Management if the MVO data matches what is in the radio. In this case, the radio can only be written using Wi-Fi or programming cable.
In order for the radio to be programmed using OTAP, not only the OTAP key needs to be present and match that in MOTOTRBO Radio Management but also the above MVO and configuration data must match.
It is a bad idea to write unknown radios using OTAP! With the very low data rate; contention and overhead, it will take very long to write an entire codeplug over the air. The likelihood that write jobs will fail is very high in this case.
My suggestion would be to go to each site; configure the radio for OTAP using CPS and save the written codeplug. Then once a number of (or all) radios have been done, import these codeplungs into Radio Management. Once imported, any changes must be made from there.
