1.4 CMX909B, CMX969, FX919B, FX929B Modem Features
The CMX909B, CMX969, FX919B, and FX929B components include Gaussian filtered minimum
shift keying (GMSK) and four level frequency shift keying (4 Level FSK) modems. They execute a
rich set of communication protocol tasks to maximize performance and minimize end product
power consumption and cost. Well suited to portable wireless applications, these modems
include the following automated functions:
• Bit or symbol synchronisation
• Frame synchronisation
• Forward error correction (FEC)
• Data interleaving for FEC enhancement
• Cyclic redundancy checking (CRC)
• Block transmit and receive tasks:
Header, Intermediate, and Last block formats
• Support for protocols such as MDC4800, Mobitex™ and RD-LAP™.
1.5 Handling Precautions
Like most evaluation boards, the EV9000 is designed for use in office and laboratory
environments. The following practices will help ensure its proper operation.
1.5.1 Unpacking
Ensure that all of the items mentioned in the separate Information Sheet (EK9000) are present in
the correct quantities. Notify CML (via your distributor) within 7 working days if the delivery is
incomplete.
1.5.2 Static Protection
The EV9000 uses low power CMOS circuits which can be partially or completely damaged by
electrostatic discharge. Partially damaged circuits can erroneously function and provide
misleading test results which can be time consuming (and extremely frustrating) to resolve.
Before handling the EV9000, discharge your body by touching a grounded connection or by using
a wrist strap. Work surfaces and tools (e.g. a soldering iron) should also be grounded before they
contact the EV9000.
1.5.3 Cleanliness
Because some EV9000 circuits are very high impedance, it is important to maintain their
cleanliness. All flux and other contaminants should be thoroughly removed after making any
modifications.

Notes:
1. Customers using the revision 002 motherboard (PCB) should note that jumpers E13 to E18
inclusive, which are mentioned in the EV9000 User Manual, only exist on the revision 003 PCB.
Customers should retain their copy of the DB900 User Manual for the description of the revision
002 PCB, but should use the EV9000 User Manual for a description of the latest software.
2. Customers evaluating FX909A may use the FX919B/929B software (ES9000xx.EXE) with the
“FX909A” chip selected. Customers should also remember to set the chip type and driver revision
select button (Figure 4) to the "Rev 1" position when evaluating the FX909A.
3. Customers wishing to evaluate FX919A or FX929A devices may use either revision 002 or 003
motherboard (PCB), but should continue to use the DB900 User Manual and "DB" software
(variously described as DB900.EXE v1.11 or CML Rev 4), available separately from CML.
Releases of EV9000 executable software marked Rev 4.1 or later should not be used as they
exercise features only available on the FX919B and FX929B devices.
4. FX909, FX919 and FX929 devices are not supported with the EV9000 Evaluation Kit.
5. Older personality boards had identification tags marked "A", "B", etc. The latest personality boards
have a mark placed against the device type with which they are to be used (eg. "909-38" for a
CMX909B operating at 38.4kb/s, etc). The layout of the latest blank personality board is shown in
Figure 2: when configured for a particular device, surface mount capacitors are soldered to the
appropriate locations and the board is marked, as described above.

1.9 Limitations
1.9.1 Software
The EV9000 software uses Microsoft Windows to ease setup and operation while providing
flexibility and power. However, the high sustained throughput required of the parallel port
connection to the EV9000 Evaluation Kit cannot be supported by Windows. As a result, the
EV9000 software bypasses some DOS and Windows conventions. Please note that concurrent
tasks will be suspended during execution of the EV9000 sofware. Network software may have to
be restarted after using this evaluation kit. The EV9000 software will also stop the PC’s clock, so
timestamps when saving files may not be accurate.
The EV9000 software will occupy all the PC’s resources during various tests. This prevents
keyboard activity from being recognized during test execution. Any tests which wait until a
modem produces a specific logic output signal (e.g. BFREE becomes logic 1) will execute
indefinitely if the test setup is inappropriate. The program may appear to be stuck in such a case.
The EV9000 HALT switch must be pressed to terminate the test. Please note that traditional
Windows commands such as Alt-Tab and Alt-Ctl-Del may not work when the software is busy.
Trying to use the software without an evaluation kit connected to the PC parallel port may cause
the software to hang if a test is executed. If this happens, pressing the Alt-Ctl-Del keys on the PC
keyboard may enable you to quit from the application. Otherwise, a hard reset of the PC will have
to be performed.
Please note that the EV9000 software is NOT suitable for use under Linux, OS2, Windows '2000
or Windows NT operating systems.
In addition, some atypical PC’s may have software and/or hardware incompatibilities with the
EV9000 Modem Evaluation Kit.
1.9.2 Hardware
1.9.2.1 Initialising
There is no hardware reset switch or function in the EV9000 hardware design. The HALT switch
(SW1) produces a signal used by the EV9000 software to indicate that a test should be
terminated. In order to be sure of the state of the hardware, the EV9000 software must be started
after the EV9000 is powered and the parallel port connection has been made between the PC and
EV9000. Failure to follow this procedure could produce spurious commands which affect the
hardware state. Upon being started, the EV9000 software will initialise all of the EV9000
hardware.
1.9.2.2 Parallel Port Compatibility
The EV9000 parallel interface design is compatible with most PC parallel ports. However, the
integral pull-up resistors provided with certain PC parallel ports are too high in value to support the
required digital signal speeds. Accordingly, the EV9000 parallel port interface circuit includes
supplementary 560Ωpull-up (to +5V) resistors on pins 1, 14, 16, and 17 of the DB25 parallel port
connector. These may not be needed when interfacing to certain types of PC and may be
disconnected by removing jumpers E13, E14, E15 and E16 if the PC has insufficient drive
capability on its parallel port. One should also use a parallel port cable less than, or equal to, 1.5
metre long because the capacitance of longer cables limits signaling speed. Nonetheless, in
some cases a PC’s parallel port may still not operate quickly enough.

2.0 Quick Start
2.1 Introduction
This section provides instructions for users who wish to rapidly start experimenting with the
EV9000 using 8kb/s GMSK modulation with the CMX909B - and without reading all of the detailed
instructions. Brief instructions for reconfiguring the EV9000 to evaluate FX919B, FX929B or
CMX969 products are also included. The “quick start” setup connects the two modem channels
so that each channel’s Tx output is connected to the other channel’s Rx input. These instructions
assume that the EV9000’s factory adjustments have not been altered. If they have, the EV9000
jumper positions and Rx / Tx signal gain and bias controls must be adjusted for the “quick start”
procedure to be successful. If the EV9000’s jumpers or gain and bias controls have been altered,
refer to Section 3.3.
2.2 First...
Review Sections 1.5 to 1.9 above. Don’t worry, those sections are very short and will help you to
avoid damaging the EV9000 or your equipment.
2.3 Second - Setup
1. Select which type of modem to test. The EV9000 comes with CMX909B modems installed
along with their appropriate personality plug-in boards. If you want to use a different modem,
carefully remove the installed modems with an IC extraction tool and install a matching pair
of modems. (If you do not have an extraction tool, a small flat bladed screwdriver can be
very carefully inserted between the IC and its socket at each end. Do this a little bit at a time,
twisting the screwdriver blade and alternating between each end of the IC until it lifts free of
its socket. Take care not to lever against other components or the PC board as they may be
damaged.) Make sure you properly orient the ICs to ensure pin 1 is in the proper socket
location, as shown in Figure 1.

2. Connect the appropriate crystal into the circuit according to the following directions:
• IF CMX909B modems are installed, change jumpers E5, E6, E10 and E11 to position A.
• IF CMX969, FX919B or FX929B modems are installed, change jumpers E5, E6, E10 and
E11 to position B. (For more information, see Table 12 and Figure 10).
3. Select and carefully install the appropriate pair of personality plug-ins to match the selected
modem according to Table 2. The layout of a blank personality board is shown in Figure 2.
