    4.7 FRONT PANEL STATUS INDICATORS INDICATOR FUNCTION Fault The Fault will be indicated when the main Power Supplie deviate from the design parameters. The Amplifier will revert to RF OFF mode. When either a Thermal condition occurs outside design parameters. Should an excessive temperature condition occur while monitoring the SOLID STATE temperature of the Heat sink temperature the Amplifier will revert to RF OFF mode.
  • Page 20 4.7.2 DATA SHEETS Provided with each Amplifier are specific Test Data Sheets measured from the amplifier using a calibrated 50 Ohm Pad to assist the operator in maximizing the performance of the Wide Band Amplifier. The accuracy of the Metering is ± .5 dB (nominal) so to provide the operator with the ability to maximize the performance of the wide band amplifier.

  • Page 21: Principals Of Operation

    It is not advisable to over drive any amplifier and depend on protection circuits to maintain proper gain control. PMI makes available with each shipped amplifier specific data and curves so the operator will know the proper input signal levels to more efficiently operate the amplifier refer to Paragraph 4.7 herein.

  • Page 22: Remote Interface

    RS-232, a standard which defines the communication between DTE, data terminal equipment to DCE, data communication equipment. The PMI Amplifiers have a RS-232, serial interface. All amplifier functions can be controlled by coded messages sent over the interface bus via the 9-pin D-type socket connector on the rear panel of the unit.

  • Page 23: Ethernet

    ETHERNET INTERFACE The Amplifiers have an Ethernet Interface. All amplifier functions can be controlled by coded messages sent over the interface bus via RJ-45 connector on the rear panel of the unit. 6.3.1 Description The Ethernet Interface allows the Amplifier to communicate with and participate in a Local Area Network using RJ-45 cable.
  • Page 24 6.3.2 Ethernet Wiring Connect the RJ-45 port of the amplifier to a computer cable on 100BaseT UTP Cat5 cable. PMI uses Lantronix XPort device as an interface to the remote Ethernet.
