Brief Description

The EV8000 Evaluation Kit comprises two boards. The signalling processor board contains an
FX828 and an FX829. The signalling processor board is powered from a single 8 - 35V dc power
supply; an on-board regulator sets 3.3V or 5.0V operation. LEDs indicate the status of the FX829
carrier detect output and the FX828 comparator output. Both of these lines are available on the
same connectors as the C-BUS. The FX828 and FX829 may be driven from a common external
clock, or from a common crystal oscillator. The supply current of either target device may be
measured by removing the appropriate jumper. A user prototyping area is provided and important
signals can be monitored by test points. There is an on-board microphone and a loudspeaker
output.
C-BUS signals can be applied at either of two connectors (J1 or J2). The other can be used to
add future C-BUS evaluation kits in parallel with the EV8000. A third connector (J3) provides a
daisy chained C-BUS to enable a second EV8000 signalling processor board to be controlled
from the same PC. The signalling processor board can also be used with a user's own µC board,
with appropriate software. Component footprints are provided in case the user requires level
shifting between the C-BUS input logic HI and the V
The µC board is fitted with a PIC µC containing the firmware to interface a PC serial port to the
signalling processor board C-BUS. The EV8000 is controlled by Windows

  • Page 4: Preliminary Information

    Evaluation Kit User Manual for FX828 and FX829 EV8000 Preliminary Information 1.2.1 Laboratory Equipment The following laboratory equipment is needed to use this evaluation kit: 1.2.1.1 8 - 35V DC Power Supply (which can also be used to supply the PIC programming voltage, if set to 13V).

  • Page 5: Quick Start

    Ensure the PC software supplied is set up as detailed in Section 1.6.3.1. The EV8000 boards each have connections for a single 8 - 35V dc power supply. Only one board (as shown in Figure 1) needs to be connected as power is supplied to the other board over the 20-way flat cable.

  • Page 6: Operation

    Evaluation Kit User Manual for FX828 and FX829 EV8000 1.3.2 Operation This evaluation kit has no inherent functionality without the µC board and appropriate firmware and PC software. The signalling processor board may be used independently of the µC board, if the user wishes to interface to a different type of µC.

    Evaluation Kit User Manual for FX828 and FX829 EV8000 1.6.3 Software Description - Signalling Processor Board 1.6.3.1 Installation The ES8000 Windows Application Software consists of a single executable file named ES8000xx.EXE, where xx refers to the version number. Copy this from its 3.5” floppy disk to the hard disk of the user’s PC.
  • Page 17 Ensure all of the hardware is connected correctly. Follow the ‘Starting the ES8000 Windows Application Software’ instructions described earlier. When the ES8000 Windows Application Software is executed a pop-up window asks the user to switch on the EV8000 kit. Switch on the power supply feeding the signalling processor and µC boards.

  • Page 23 Update button. This will also acquire the settings of the read registers. The read register settings will then be displayed on the device form view. To minimise data exchange between the PC and EV8000, only modified write register settings are passed to the µC.
  • Page 24 FX828 will display CTCSS and Selcall tones, depending on the state of the Tone Decoder Mode bit in the Signalling Set-up write register. For the FX828, both sets of tones are stored in memory but only one set is sent to the EV8000 Evaluation Kit, depending on the Tone Decode mode setting.

  • Page 29 To allow the user to perform FX829 Bit Error Rate Testing (BERT) the EF8000 firmware contains a BERT routine, configured by the ES8000 Windows Application software. This facility requires two EV8000 signalling processor boards (near and far) and user input to both near and far FX829 device forms before BERT can commence.

    Evaluation Kit User Manual for FX828 and FX829 EV8000 Notes: Assembler output files must be in the Intel hex format (.HEX) in order to be usable by this programming software. The PIC µC supplied has a Configuration Word which is preset to 3FB9H if it is a PIC 16C74JW or 16LC74JW, or to 3FB1H if it is a PIC 16C74AJW or 16LC74AJW.

  • Page 32: Troubleshooting Guide For The Es8000 (V 1.0) Software

    Answer: This may occur due to an unconnected serial cable or EV8000 PSU problem. The ES8000 Windows Application Software will not function correctly after a ‘Cannot Write Port’ error message has occurred. Shutdown the ES8000 and turn off the power supply feeding the signalling processor and µC boards.
