1.1 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 VDD level of the signalling processor board.
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 WindowsTM software on the PC.

1.2 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).
1.2.1.2 A µC control board, together with appropriate firmware and a user interface. This kit contains a
suitable control board, which is fitted with a pre-programmed PIC 16LC74JW (or similar) µC.
1.2.1.3 An 8Ωloudspeaker.
1.2.1.4 An IBM compatible PC; 40MHz '386DX or better with 8MB of RAM, running Microsoft Windows
3.11 / '95 / NT having a serial port configuration of 8 data bits, no parity, 1 stop bit and 19,200
baud with hardware handshake but without CR -> CR/LF conversion.
The following laboratory equipment is needed to re-program the PIC µC in this evaluation kit:
1.2.1.5 If the evaluation kit is to be programmed via the serial port (J3), then a PC running DOS, or a
DOS window under Windows 3.11 or '95, will need to be used with the PIC programming software
supplied ( PICPROGA.EXE ).
1.2.1.6 As an alternative to on-board programming, a PIC 16-series Development System (available
from Arizona Microchip Technology), or a suitable PIC programmer, together with PIC
development software, may be preferred.
1.2.1.7 MPASM assembler or MPLAB software is required for re-assembling the source code. These
tools are available from Arizona Microchip Technology.
1.2.1.8 A UV-eraser to remove the pre-programmed PIC µC firmware.
1.2.2 Handling Precautions
Like most evaluation kits, this product is designed for use in office and laboratory environments.
The following practices will help ensure its proper operation.
1.2.2.1 Static Protection
This product uses low power CMOS circuits which may be damaged by electrostatic discharge.
Partially damaged circuits may function erroneously, leading to misleading results. Observe ESD
precautions at all times when handling this product.
1.2.2.2 Contents - Unpacking
Please ensure that you have received all of the items listed on the separate information sheet

1.3 Quick Start
This section provides instructions for users who wish to experiment immediately with the
evaluation kit. A fuller description of the kit and its use appears later in this document.
1.3.1 Setting-Up
THE EV8000 COMES PRE-CONFIGURED FOR OPERATION AT 5.0V.
The µC board contains a socket for a 40-pin DIL PIC (or compatible) general-purpose µC, which
the user may re-program with his applications software. The µC board comes with a pre-
programmed PIC 16C74AJW or equivalent containing communications firmware and application
specific demonstration firmware for the EV8000 evaluation kit.
The kit also contains a 9-way D-type RS232 cable (for connection to a PC), as shown in the Block
Diagram of Figure 1. No board adjustments are required by the user.
The C-BUS connector on the signalling processor board, J1 or J2, should be linked to connector
J1 on the µC board with a 20-way flat cable, as shown in Figure 1, connecting pin 1 to pin 1.
Analogue signals can be input or monitored at connector J6.
BEFORE APPLYING POWER, PLEASE CHECK THE FOLLOWING:
ENSURE THE PIC µC IS PLUGGED INTO SOCKET U2 ON THE µCBOARD.
ATTACH THE 9-WAY RS232 CABLE TO CONNECTOR J3 ON THE µCBOARD AND THE
SERIAL PORT OF A PC.
ATTACH THE 20-WAY FLAT CABLE TO CONNECTOR J1 ON THE µCBOARD AND
CONNECTOR J1 ON THE SIGNALLING PROCESSOR BOARD. PIN 1 MUST CONNECT TO
PIN 1.
Connect any other equipment as shown in Figure 1.
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. If the µC board supplied is not used, then power will need to be applied to the
signalling processor board instead. Each board has its own power supply regulator chip, with a
jumper to select 3.3V or 5.0V (default) operation.
Ensure that the component value jumpers on each of the EV8000 evaluation boards are correctly
set for 3.3V or 5.0V operation. Please refer to Sections 1.6.1.1 and 1.6.2.1 for further details.
MAKE SURE BOTH BOARDS HAVE THIS LINK SET TO THE SAME VOLTAGE. DAMAGE
MAY RESULT IF THIS STEP IS NOT OBSERVED. DO NOT OPERATE THE
µCBOARD WITH ITS VOLTAGE SELECTION LINK REMOVED. THE µCBOARD AND
SIGNALLING PROCESSOR BOARD VOLTAGE SELECTION LINKS HAVE DIFFERENT
CONFIGURATIONS.

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. The user will then have to supply his own
software.
The µC board is designed to control the operation of the signalling processor board. The
firmware which is pre-programmed into the PIC µC has both communications and application
specific functions. These functions are controlled from the PC software (ES8000) which runs in a
Windows environment.
Refer to Section 1.6.5 for the known software bugs and Section 1.6.6 for the troubleshooting
guide.
The PICPROGA.EXE program can be used to re-program the PIC µC firmware, if required.

1.6 Detailed Description
1.6.1 Hardware Description - Signalling Processor Board
1.6.1.1 Operating Voltage
Jumper JP1 is used to select the operating voltage. Open circuit selects 5.0V operation (default)
and closed circuit (link fitted) selects 3.3V operation.
1.6.1.2 Clock/Oscillator
The evaluation devices may use either an external clock or their own xtal oscillator. A 4.032MHz
xtal is provided on-board for the latter method. The links on jumpers JP2 and JP3, which are
normally fitted, select the xtal oscillator. An external clock may be supplied to JP3 pin 1 once the
links have been removed.
1.6.1.3 Microphone
By fitting a link to jumper JP7, the on-board electret microphone is connected via a buffer amplifier
to the MICIN input of the FX829. The signal applied to the FX829 can be monitored
at TP8. A push-to-talk (PTT) switch is also provided.
1.6.1.4 Loudspeaker
An 8Ωloudspeaker output is provided at the 3.5mm mono jack socket J5. The signal source for
the loudspeaker can be either the FX829 (default) or the FX8x8, link selectable at jumper JP6.
1.6.1.5 C-BUS and optional level shifting.
There are identical connectors (J1 and J2) either side of the board for C-BUS. This enables the
C-BUS source to be connected either side of the signalling processor board and also enables
future C-BUS evaluation boards to be connected in parallel. A third connector (J3) allows the
daisy chaining of a second signalling processor board with alternative /IRQ and /CS lines. This
allows for the emulation of both ends of a radio link, using a single PC.
If it is desired to operate the signalling processor board at VDD = 3.3V with the interface to C-BUS
operating at VDD = 5.0V, then level shifting components will need to be added to the signalling
processor board. Level shifting can be added to the C-BUS interface by removing solder links
LK4 to LK7 and fitting the following components:
A 74F07 in position U5.
A pull-up resistor pack in position RP1, suggested value 470Ω.
A pull-up resistor in position R22, suggested value 22kΩ.
A de-coupling capacitor for U5 may be fitted in position C22, suggested value 47nF.
1.6.1.6 Analogue re-configuration
Some discrete components and links around the target devices are socketed to allow path gains
to be adjusted. Also the analogue connector J6 has a second bare footprint, J7, which, in
conjunction with the removable components and links, can be used as a patch board to allow the
user to re-arrange signal paths as required.
1.6.1.7 IDD Measurement
The current consumption of the FX829 or the FX828 may be measured by removing the link on
jumper JP4 or JP5 respectively and replacing it with a multimeter.

Evaluation Kit User Manual for FX828 and FX829 EV8000
©2004 CML Microsystems Plc 15 UM8000/4
1.6.2 Hardware Description - µCBoard
1.6.2.1 Operating Voltage
Jumper JP1 is used to select the operating voltage. A link fitted at position 1,2 selects 3.3V
operation and at position 2,3 selects 5.0V operation (default). Do not operate this board with the
link on jumper JP1 removed.
1.6.2.2 Clock/Oscillator
A 4MHz xtal is the highest frequency xtal that may be used with a PIC16LC74(A)JW at
VDD = 3.3V. The PIC 16C74(A)JW has a similar limitation and is fitted for availability reasons.
Although rated at 5.0V, it has been found to work successfully at 3.3V. The links on jumpers JP2,
which are normally fitted, select an on-board 4MHz xtal. An external 3.58MHz clock, for
example, may be supplied to JP2_1 (1) once the links have been removed, taking care to adjust
any firmware timing routines accordingly.
1.6.2.3 RS232 Interface
The RS232 interface (connector J3) has its communications protocol determined by the µC

1.6.3.5 Near and Far ES8000 Definitions
The near EV8000 signalling processor board is connected to the µC board via the J1 connector.
Therefore all FX8xx devices located on the near signalling processor board are considered to be
near devices and are controlled by near device forms.
The far signalling processor is created by taking a signalling processor board out of a second
EV8000 evaluation kit. It should be connected to the near signalling processor board by using
another 20-way flat cable between connector J3 on the near board and connector J1 on the far
board. Pin 1 on connector J3 should be connected to Pin 1 on connector J1. All FX8xx devices
located on the far signalling processor board are considered to be far devices and are controlled
by far device forms.
Note: In certain parts of the ES8000 Windows Application Software the variables CBUS and CBUS2 are
used. These correspond to the near and far boards respectively.
1.6.3.6 ES8000 and EV8000 Startup Procedure
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.
When power has been applied the Add Device pop-up window is opened. If the user is ready to
add a device form to the view select the device and click on OK. Click on cancel if you do not
require a device form.
Perform a General Reset when the first device form is opened, any further device forms added
will not require a General Reset unless they have been opened on the other C-BUS (near or far).
If the ES8000 Windows Application Software is executed with power already applied to the
signalling processor and µC boards, simply press the reset switch (SW1) on the µC board. The
Add Device window should now open.
If these methods fail, shutdown the ES8000 application and turn off the power supply to the
signalling processor and µC boards. Repeat the procedure described above.

1.6.3.9 Menubars
The main application menubar which resides at the top of the main window contains five pulldown
menus. This menubar is available for use until a device form is opened. Whenever a device form
is active a form menubar resides at the top of the main window. This form menubar is currently
the same for all devices and is similar to the main menubar except for an additional pulldown
menu called Local (disabled in Version 1.0) and three additional Global pulldown menu
commands called General Reset, BER Test and Demo1 (disabled in Version 1.0). The
pulldown menus from the form menubar are illustrated below.
Setup Pulldown Menu
This menu allows the user to
open the Add Device pop-up
window, initialise the RS232
communications link to the µC
board and reset the µC board.

1.6.3.10 Adding a Device Form
There are two ways to add device forms to the view. The quickest method is to click on the Add
Device toolbar button which opens the Add Device pop-up window. The second way involves
clicking on the Setup menu and then selecting the Add Device command.
The Add Device window gives the user the choice of near and far devices. The user should
select the required device form corresponding to the device located in the near or far signalling
processor board. Finally, click on the OK button.
If a device form already exists within the main view, this selection will not be available from the
Add Device pop-up window.
The cancel button allows the user to exit the window without selecting a device form.
If the user attempts to open more than four device forms (Version 1.0 maximum) during an
evaluation session, a pop-up window will notify the user that no more device forms are available.
1.6.3.11 Deleting a Device Form
Windows NT and '95
To close a device form (iconised or open), click on the close button in the upper-right corner of the
device form.
Windows 3.11
To close a device form (not iconised), click on the upper-left corner pulldown menu of the device
form, and click on the close command.
1.6.3.12 Switching between Opened Device Forms
A device form must have the focus to allow the user to modify the Write registers and view the
settings of the read registers.
The device form focus can be switched by simply clicking on the required form. Switching the
focus can also be achieved by clicking on the Window pulldown menu, and then click on the
required device form.
1.6.3.13 Device Forms
The evaluation software has been designed so that each device has a corresponding device form.
The device forms have been created based on the device data sheets to allow the user to easily
and quickly set up a device in the required operating mode. Additional FFSK sections are
included on the FX829 device form, as it was considered important to have these features
available. Future releases of the ES8000 software will include device demonstration windows.
The device forms for the FX828 and FX829 are illustrated on the following pages. It should be
noted that this evaluation kit will also support an earlier device, the FX818, which has now been
discontinued.
