Connecting the CRD 3400 to Other Cradle Chains
The CRD 3400 cradle can be chained to:
another CRD 3400
t
a Series 3000 cradle chain (31XX, 38XX, 33XX)
t
a CRD 4600 cradle chain.
t
Up to 96 CRD 3400's can be chained together. If the CRD 3400 is chained in combination
with other cradle chains, the total number of linked cradles is limited by the constraints of
the other cradle chains. For example, a CRD 4600 cradle chain is limited to 59 slave cradles
depending from a single master cradle.
To connect one or more CRD 3400s in a chain (refer to Figure 3-12):
1. Disconnect the power jack from the power source for all cradles included in the
chain.
2. Connect Cradle 1 to the host as described on page 3-10.
3. Remove Cradle 2's back housing.
4. Plug an RS-232 cable's male DB-25 connector in Cradle 1's chaining port.
5. Plug the RS-232's female DB-25 connector in the Cradle 2's interconnect (host) port.
6. Plug the power supply jack in Cradle 2's power port.
7. Replace the back housing on each Cradle.
8. Repeat the process for each CRD 3400 in the chain.
