LinkNet™ LNKA800 RF MODULES ! USER MANUAL DCM000000054 De-Rating Chart To maintain the FCC Spurious Emissions limit of -13 dBm maximum, for multiple carriers it is necessary to de-rate their power level. For FM carriers, they need to be de-rated as shown... Number of Carriers Power per Carrier 1 +37 dBm 2 +26 dBm 3 +24 dBm 4 +22 dBm 5 +20 dBm 6 +19 dBm 7 +18 dBm 8 +17 dBm 9 +16 dBm 10 +15 dBm 15 +13 dBm 20 +11 dBm 25 +10 dBm 30 +9 dBm For complex CDMA, TDMA, GSM, etc.
LinkNet™ LNKA800 RF MODULES ! USER MANUAL DCM000000054 Power On Self Test (POST) Each system module automatically performs a self-diagnostics when inserted into the system Card-cage. These tests determine that the unit is a) correctly installed in the Card-cage and b) not damaged in transit. • • • • All six of the LED’s on the front panel will flash 3 times If the LED’s do NOT flash three times, then remove the module, check the power source, and re-insert the module, (See Installation Instructions).
LinkNet™ LNKA800 RF MODULES ! USER MANUAL DCM000000054 Normal Operation The LNKA800 Module has six LED’s on the faceplate: 1. OPERATING - Operating normally. 2. STANDBY – Under the control of the Control Module, the LNKC1900 Module has the ability to act as a duplex transmitter, sitting perpetually in Stand by Mode waiting for the primary transmitter to fail. This LED should be constant Amber.
