Onboard Features
2.7
EPP mode assumes that the parallel port can be used to connect more than one peripheral
device using multiplexor or daisy chain configurations.
A multiplexor is an external device that permits up to eight parallel port devices to share a
single parallel port.
A daisy chain device has two ports: input and output. The input port is connected either to
the host parallel port or the daisy chain device in front of it. The output is used to connect
the next peripheral device to the daisy chain. The last device, however, can be one without
daisy chain support.
2.6.3. ECP Mode
ECP (Extended Capabilities Port) works the same as EPP mode, but it will take precedence
over the EPP mode when addressing multiple logical devices in a single physical product.
While the EPP mode may intermix read and write operations without any overhead or
protocol handshaking, the ECP mode negotiates data transfers using a request from the host
and an acknowledgment from the peripheral.

NOTE
For more information on the ECP protocol, please refer to the
Extended Capabilities Port Protocol and ISA Interface Standard (available
from Microsoft Corporation) or contact our Technical Support department.
