2.1
Quick Start
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.

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.
