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
(EK8000) and notify CML within 7 working days if the delivery is incomplete.

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.
