Quick Start

This section provides instructions for users who wish to experiment immediately with the

EV9900A evaluation kit, by controlling it from a PC via the EV9902 Interface Kit.

A fuller

description of the Interface Kit and its use appears later in this document. Before using this kit, it

is recommended that the user read the datasheets for the CMX990, the EV9900A and the

hyBoard-XS.

The latest versions of these documents, together with the "ES9902xx.exe"

software, can be found at http://www.cmlmicro.com/ and at http://www.hyperstone.com/ for the

hyBoard-XS documentation.

3.1.

Setting-Up

Before the kit can be powered-up, the hyBoard-XS jumpers must be set to their default values

(see Table 2) and the following connections must be made:

•

The EV9902 Interface Card, J1, J2 and J4, to the hyBoard-XS, X1, X2 and X3

•

The EV9902 Interface Card, J3, to the EV9900A Evaluation Kit, J13 – using the supplied

ribbon cable

•

The hyBoard-XS, J4, to a spare USB port on the PC via a USB cable (not supplied)

•

The hyBoard-XS, via the supplied power cable, to the 5.0V D.C. power supply

•

The EV9900A main supply to the 7.2V D.C. power supply

•

The EV9900A PA supply to the 3.6V D.C. power supply

•

The EV9900A RF output, TXOUT (J9), must be connected to a suitable 50

Ω load

NOTE: Before power is applied to the EV9900A PA supply, a suitable 50

Ω load must be

connected to the PA output, TXOUT (J9), in the default configuration. Failure to do so may

result in permanent damage to the PA device. See the EV9900A datasheet for full details.

Operation

3.2.1.

Applying Power

Before applying power, refer to section 2.4, Important Information, above.

Once the connections detailed in section 3.1 have been made, the kits should be powered-up in

the following sequence:

1.

The 5.0V D.C. power supply

2.

The 7.2V D.C. power supply

3.

The 3.6V D.C. power supply

On application of the 5.0V supply the hyBoard-XS LED, LED6, will flicker momentarily and then

remain constantly on.

3.2.2.

Running the Software

To start the software, run the executable “ES9902xx.exe” (where xx is the version number). This

software is included in the EV9902 software zip file, which can be downloaded from the CML

website.

For a detailed description on using the ES9902 application, see section 6.1.
