PDT 3400 Product Reference Guide
9. When all the cradles are chained, connect the power plug for each cradle in the chain
to a power source.
Note: Each cradle in the chain has its own power supply. Be sure to connect all
power supplies for chained cradles to a power strip connected to a standard
electrical source. Then power the power strip on and off, not each cradle.
When chaining cradles together, only the cradle closest to the host blinks 7
times. The LEDs on all other cradles in the chain go out after the 4-second
ON period. If these cradles blink 7 times, there is a cradle problem.
If you are connecting the CRD 3400 cradle chain to a Series 3000 cradle chain (e.g., 31XX
or 38XX cradles), the cradles can be linked in any order.
If you are connecting a CRD 3400 cradle chain to a CRD 4600 cradle chain:
1. Position the master CRD 4600 at the end of the 3400 cradle chain, with any slave
4600 cradles following the master cradle.
2. Use the RS-232 Null Modem DB-25 Male to DB-25 Female Cradle Interconnect
Cable (p/n 25-15749-01) to connect between the last CRD 3400 in the chain and the
master CRD 4600.
