Onboard serial port 2/COM 2
This option enables serial port 2 on the CPV5000 and specifies the base I/O
port address for serial port 2. The settings are: Auto, 3F8h, 2F8h, 3E8h, 2E8,
or Disabled.
Onboard parallel port
This option enables the parallel port on the CPV5000 and specifies the parallel
port base I/O port address. The settings are: Auto, 378h, 278h, 3BCh, or
Disabled.
Parallel port mode
This option specifies the parallel port mode. ECP and EPP are both
bidirectional data transfer schemes that adhere to the IEEE P1284
specifications. Refer to Table 7-11 for parallel port mode setting information.
Setting
Normal
The normal parallel port mode is used. This is the default setting.
Bi-Dir
Use this setting to support bidirectional transfers on the parallel port.
EPP
The parallel port can be used with devices that adhere to the Enhanced
Parallel Port (EPP) specification. EPP uses the existing parallel port signals
to provide asymmetric bidirectional data transfer driven by the host device.
ECP
The parallel port can be used with devices that adhere to the Extended
Capabilities Port (ECP) specification. ECP uses the DMA protocol to achieve
transfer rates of approximately 2.5 MB. ECP provides symmetric
bidirectional communications.
Parallel port DMA
This option is only available if the setting for the Parallel Port Mode option is
ECP. The settings are Disabled, DMA CH (channel) 0, DMA CH 1, or DMA
CH 3.
