Bandwidth Considerations when Daisychaining

Each cradle added to the daisychain impacts the bandwidth provided to the inserted MC75As, particularly when the
MC75As attempt to send and receive at data rates that exceed the bandwidth provided to the chain (typically 100
Mbps). If an MC75A in a daisychained cradle does not use its bandwidth, that bandwidth is allocated to other
inserted MC75As.
Table 2-3 shows available bandwidth, based on 100 Mpbs, for the maximum number of daisychained cradles, with
each attempting transmission at the maximum data rate.

* The maximum bandwidth capacity for the mobile computer is 12,000,000 bits/sec.
** Depending on the application, allocated bandwidth may not be adequate.
Note: 100 Mbps is the theoretical maximum. This rate is never actually achieved in any Ethernet installation.

Ethernet Cradle Drivers

The MC75A includes Ethernet cradle drivers that initiate automatically when you place the MC75A in a properly
connected Four Slot Ethernet cradle. After inserting the MC75A, configure the Ethernet connection:
