Chapter 2 Operation 2 Introduction This chapter contains information for the standard operation of the LNKF100 Modules. 2.1 Software Set-Up The LNKF100 module is shipped with the following factory set options: Table 3 LNKF100 Factory Set Options OPTION RANGE OF VALUES DEFAULT VALUE Frequency See Model Chart Order Specific Receive Threshold –110 to -50 dB -95 dB Receive Hysteresis 1 to 10 dB 3.
Power On Self Test (POST) 2.3 Power On Self Test (POST) Each module automatically performs a self-diagnostics when inserted into the system card-cage. These tests determine that the unit is correctly installed in the card-cage and 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).
Normal Operation 2.5 Normal Operation The LNKF100 Module has six LED’s on the faceplate: OPERATING - LED will flash GREEN when RF Data is present and unit is operating normally. STANDBY – Under the control of the Control Module, the LNKF100 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.
Simplex Operation 2.6 Simplex Operation • For back-to-back Simplex operation, the LinkNet Modules to be used MUST be interconnected as shown: Figure 2-2 LNKF100 Simplex Interconnection • • This connection is made using a custom male DB15 to male DB15 cable as shown above interconnected between the two LNKF modules. This cable is plugged into the two module's control ports (see DCM000000008 "Control Connections") on the back of the chassis they are installed in.
Chapter 3 Antenna Installation 3 Introduction This chapter contains antenna installation and warning information for the LNKF100 Modules. 3.1 Antenna Installation • • All antenna installation to be performed by qualified technical personnel only. Antenna installation instructions and locations below are for the purpose of satisfying FCC RF Exposure Compliance requirements.
FCC Information to Users ANTENNA INSTALLATION CAUTION ALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED TECHNICAL PERSONNEL ONLY. ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR THE PURPOSE OF SATISFYING FCC RF EXPOSURE COMPLIANCE REQUIREMENTS, AND ARE NOT OPTIONAL. ALL ROOF TOP ANTENNA INSTALLATION MUST BE SUCH THAT NO PERSON CAN TOUCH THE ANTENNA, OR APPROACH CLOSER THAN 10 METERS.
Chapter 4 Return for Service 4 Introduction This chapter contains return for service and parts and accessories information for the LNKF100 Modules. 4.1 Return For Service Procedure When returning products to Powerwave Technologies Inc., the following procedures will ensure optimum response. 4.1.1 Obtaining An RMA A Return Material Authorization (RMA) number must be obtained prior to returning equipment to the factor for service.
