  2. Focus

    This page relates to the PPEViewer, PPE Monitor tab.

     

  3. Overview

    The PPE Monitor tab displays the communications between the PPEViewer and the E2000 system. This communication is always on Port A, on the rear of the E2000. This version only monitors one system at a time and the communications must be established and operating before this window becomes active.

     

  4. PPE Monitor Tab Description

The monitor tab is divided into two sections. The E2000 PPE Configuration and the filtered Monitor windows.

PPE Configuration Frame

 

 

 

 

 

Command Buttons

This frame contains all the command buttons which send command packets to the E2000, and more specifically the E2050 Processor Card via Port A. When command buttons are clicked the E2050 will respond when it is least likely to affect the encoding process. So there will be a short wait until the command packets can be processed. Do not click the buttons incessantly as each click sends a packet which is buffered in the E2050, and ultimately processed.

Configuration Labels

When the system E2050 resets on power up or the E2050 reset button is pressed, it sends a E2050 configuration packet to the Viewer. This is decoded and displayed as Channel, Channel Detect, System Type and Priority Active labels. The labels are described below.

  1. Channel Mask

    The channel indicator (currently either an 8 or a 4)   

    This number is related to the TNPP packet Port mask field.

    The 8 represents the Hutchison F1 channel

    The 4 represents the Hutchison F2 channel

    This mask is only used in dedicated systems. Switching systems use the frequency flag.

    The firmware will ignore any other setting and consequently no TNPP packets will be processed.

     

  2. Frequency

    The frequency indicator (currently either an 1 or a 2). Only switching systems will use this flag. It is used to indicate to the E2019 which PURC sequence to use.   

    This number is related to the TNPP packet Frequency mask field.

    The 1 represents the Hutchison F1 channel

    The 2 represents the Hutchison F2 channel

    The firmware will ignore any other setting and consequently no TNPP packets will be processed.

     

  3. System Type

    This flag is set to either Switching or Dedicated. It indicates how system 1 and 2 interact.

  4. Channel Detect

    This is the setting to make the processor look for different channels i.e. F1 and F2 in the incoming TNPP packet. All Hutchison systems do this.

     

  5. Priority Active  

    This setting turns on the priority checking on Port D of each system.

     

  6. 240 Volt Power

    This indicates if the power supply on the immediate system is operating.

     

  7. Version

    This is the current version of the E2000 firmware.

     

Refresh Button.

This button immediately clears the display then when the response to the command is deciphered it then populates the fields.

The set clock time is manually set by the small "S" command button next to the E2050 Clock time display. Whenever the Viewer is connected to the E2050 the time update is automatically sent to the E2050 every hour.

Reset WD Button

This command button is fatal. It commands the E2050 to stop activating the watchdog circuitry. This will let the watchdog hardware reset after a period of around 20 seconds. The E2050 will then immediately reset clearing the queues and firmware flags as if it had been power cycled.

Since this is such an intrusive event, the command is password protected. The reset command to the Processor is tested with a message box to ensure the selection is not made accidentally as shown below.

 

 

Update Time

This command button requests the E2050 to report the current time of the on board real time clock. The real time clock unfortunately is volatile in the Zworld device. However as long as the E2050 is powered the clock will keep time.

On a reset of the E2050, an up-time timestamp is recorded internally. The Update Time command also reports this time and converts it to seconds or days of up-time.

Set Clock

Since the real time clock (RTC) on the E2050 is volatile it requires setting after the E2050 is powered up. The Set Clock command sends the local workstation time to the E2050 to update the on board RTC. Now that the E2050 is powered up and the clock has been set, reseting the E2050 either remotely or by the push button on the E2050 will update the up-time timestamp with the current time.

The RTC default is the year 1980, so if the above process is not done the up-time will be incorrect.

Filtered Monitor Windows

The raw data stream is split into 4 major groups of information. The groups are

  1. TNPP (TMP) packet processing

  2. POCSAG code generation

  3. BATCH control

  4. System/Error messages

The bottom left is TMP packet processing information coming in from the serial ports. The top right are the decision rules for changing baud rates between batches. The bottom right is the POCSAG buffer information specific to the data going to air. The top left are exceptions or unusual system based messages that should not normally appear.
