Interconnecting Cradles

Up to 24 four-slot cradles can be connected in series using an RS-232 inter-cradle cable at
38.4 kbps.
Each 4-slot cradle must have its own power supply; any other method of
power connection is unsafe.
1. Plug one end of the inter-cradle cable into the communication port located on the left
end of the first cradle.
2. Plug the other end of the inter-cradle cable into the communication port located on
the right end of the second cradle.
3. Connect a power supply to the second four-slot cradle as described in the Connecting
Power section.
4. Repeat the previous steps for any additional four-slot cradles you wish to connect.
All chained cradles must be powered up at the same time.
When all chained cradles are powered up, only the master cradle's COM LED blinks seven
times (the COM LED on slave cradles does not blink).
