EXM-1MB Memory Upgrade

Operation

You must replace the CATP’s 256KB integrated circuit (IC) with the EXM-1MB Memory Upgrade ICs to increase the storage capacity for control pages and symbols. The EXM-1MB Memory Upgrade consists of two 512KB memory ICs. You will need a Phillips screwdriver and a non-conducting flat-blade tool to slip under the installed 256KB IC and pry it out of its socket.

AXT-CV and AXT-CA

To install the EXM-1MB Memory Upgrade into the AXT-CV and AXT-CA CATP:

1.Discharge the static electricity from your body by touching a grounded object.

2.Remove the AXlink connector (and other connectors if applicable) from the rear side of the CATP.

3.Flip the CATP face down onto a soft cloth, and remove the four Phillips-head screws from the bottom panel. Then, gently remove the panel.

4.Gently rotate the circuit card backward until you can lay it down flat with the batteries exposed. Figure 200 shows the location of the memory IC sockets on the circuit card.
