  • Page 5: Introduction

    The HPDA-15RMi-S is designed to be powered by a 100 to 240 VAC mains source or by a +12 to +36 VDC power source. The DC power supply may be used as a main power source for the instrument or in conjunction with the AC power supply as a backup in case of loss of the main AC power.

  • Page 6: Safety And Preparation For Use

    2.0 Safety and Preparation for Use The HPDA-15RMi-S was designed for indoor use only and is not intended for operation outdoors or in a wet environment. The instrument may be mounted in a standard 19-inch instrumentation rack or may be used on a laboratory bench. Inspect the instrument and power cords for damage before first use.

  • Page 7: Instrument Safety

    < 5mV peak-to-peak 2.2 Instrument Safety The HPDA-15RMi-S is designed to distribute RF signals with a frequency of 1 to 50 MHz . Input and output levels below +7 dBm will trigger a fault condition which can be monitored from the front panel as well as through the Ethernet interface. The recommended level for the RF input signal is +13 dBm +/- 2 dB .

  • Page 8: Front Panel Description

    3.0 Front Panel Description MONITOR AC The AC Power LED is on when AC power is applied to unit. MONITOR DC The DC Power LED is on when DC power is applied to unit. MONITOR 1 The Input 1 LED is on when the signal applied to the INPUT 1 connector on the rear panel has a level greater than +7 dBm.
  • Page 9 3.0 Front Panel Description ACTIVE CH 1 LED The ACTIVE CH 1 LED will be on when INPUT 1 is the active channel. ACTIVE CH 2 LED The ACTIVE CH 2 LED will be on when the INPUT 2 is the active channel. OUTPUTS There are ten status indicator LEDs one for each output channel.

  • Page 10: Back Panel Description

    This instrument may also operate on DC power from +12 to +36 VDC as the main power supply. When the HPDA-15RMi-S is set up to operate with both AC and DC power sources at the same time the DC power is used as backup power in case of AC power outages.

  • Page 11: Installation

    AC power failure, 5.2 Connecting RF input signals There are two RF inputs to the HPDA-15RMi-S one of which will be selected as the active channel and distributed to the ten output connectors. The RF inputs have a 50-ohm input impedance.

    2. Turn on the power or reset the power to the HPDA-15RMi-S and set the CONTROL switch on the front panel to the LOCAL position and the ACTIVE CH switch to the 1 position.
  • Page 13 5.0 Installation Once the Configure network settings link is clicked, the following dialog box will open. 4. Configure the network and record the new network configuration of the instrument: Page 9...
  • Page 14 The new network configuration will be programmed into the HPDA-15RMi-S. 5. If the wrong network configuration is programmed and you can no longer communicate with the HPDA-15RMi-S, follow the procedure outlined in the Troubleshooting section to reset the device to the Factory Configuration.

    6.0 Operation The HPDA-15RMi-S autoswitch amplifier may be operated in local control mode where the instrument is controlled by the settings on the front panel or in remote mode where the instrument is controlled by sending commands through the Ethernet interface. The mode of operation is selected through the locking switch on the front panel labeled CONTROL.

    7.2 dBm when the input signal is increasing in amplitude. The switching circuit of the HPDA-15RMi-S has approximately 0.5 dB of hysteresis to avoid multiple switching events when the amplitude of the input signal is very close to the threshold.
  • Page 22 Check the network cable and run the Digi Device Discovery Tool software on a computer that is attached to the same network as the HPDA-15RMi-S. The software should be able to locate the HPDA-15RMi-S and display the network setting of the instrument. If the instrument does not appear in the list of devices on the main screen click the refresh button.
  • Page 23 In the figure above these pins are highlighted by a red rectangle. Remove the jumper and remove power from the instrument. Replace the top cover of the HPDA-15RMi-S. The instrument should now be restored to the original factory setting with DHCP enabled.
