Page 4-22 500W Series Installation ManualRev. D 190-00357-024.10 DME Tuning (GNS 530W Only)4.10.1 DME Tuning FunctionThe GNS 530W can channel a DME based on the tuned VLOC frequency. The GNS 530W outputs 2 of5, BCD or Slip parallel DME and King Serial DME channeling format. When DME COMMON is heldlow, the GNS 530W actively tunes the DME.4.10.2 DME Tuning Electrical Characteristics4.10.2.1 Parallel DME TuningPin Name Connector Pin I/ONAV PAR DME - 8MHZ P5006 14 OutSER DME – CHAN REQ/PAR DME - 4MHZ P5006 20 Out*SER DME – RNAV MODE/PAR DME – 2MHZ P5006 21 Out*NAV PAR DME - 1MHZ P5006 33 OutNAV PAR DME - 800KHZ P5006 37 OutNAV PAR DME - 400KHZ P5006 39 OutNAV PAR DME - 200KHZ P5006 40 OutNAV PAR DME - 100KHZ P5006 42 OutNAV PAR DME - 50KHZ P5006 43 OutNAV DME COMMON P5006 22 In* These pins are outputs when the GNS 530W is configured for 2 of 5 parallel DME tuning.For each of the parallel DME tuning discrete outputs, the driver output voltage is not more than 1.0 Vwhile sinking 20 mA. The maximum off state leakage current with respect to ground is less than 10 μA.NAV DME COMMON must be pulled low to indicate to the NAV module that it is the devicechanneling the DME.NAV DME COMMON is considered active if either the voltage to ground is <1.9 V or the resistance toground is <375 Ω. These inputs are considered inactive if the voltage to ground is 11-33 VDC.4.10.2.2 King Serial DME TuningPin Name Connector Pin I/ONAV SER DME – DATA P5006 19 OutNAV SER DME – CLOCK P5006 18 OutSER DME – CHAN REQ/PAR DME - 4MHZ P5006 20 In*SER DME – RNAV MODE/PAR DME – 2MHZ P5006 21 In*NAV DME COMMON P5006 22 In* These pins are inputs when the GNS 530W is configured for King Serial DME tuningWhen NAV SER DME – DATA or NAV SER DME – CLOCK is asserted high and driving a 360 Ωload, the driver output voltage is not less than 8 V, and when asserted low is not greater than 10 mV.SER DME – CHAN REQ/PAR DME – 4MHZ, SER DME – RNAV MODE/PAR DME – 2MHz, andNAV DME COMMON are considered active if either the voltage to ground is <1.9 V or the resistance toground is <375 Ω. These inputs are considered inactive if the voltage to ground is 11-33 VDC.NAV DME COMMON must be pulled low to indicate to the NAV module that it is the devicechanneling the DME.
