LOS-CDT-500-WH with GRX QSGRJ–6P

Hello, i have an issue here, a very simple system, but did not work....
One GRX QSGRJ–6P + Sensor LOS-CDT-500-WH.. The sensor did not work
I installed the sensor on the CCI port of the GRX, I checked the manual very very hard.
after installing, i configured the GRX, went in the settings and configured the CCI port, i dont know what to do ....

Please help some one :)
