Other Settings
SW1-1 controls normal or early I/O timing compatibility:
This option allows bus timing compatibility between the EN-2400 and PCs such as those using
Chips and Technologies chipsets.
Set SW1-1 to "OFF" to select the "Normal IOCHRDY" function.
Set SW1-1 to "ON" to select the "Early IOCHRDY" function.
Normal IOCHRDY is the factory setting; you may select Early IOCHRDY to meet the timing
compatibility for some PCs. This sets the board for standard 16-Bit "AT compatible" bus timing.
Early IOCHRDY also makes the board timing compatible with the following PCs:
Compaq portable
IBM 286/30
PCs using the Chips & Technologies chipsets
SW1-2 controls the 16-Bit I/O timing:
Set SW1-2 to "OFF" to select the "Normal IO16" function.
Set SW1-2 to "ON" to select the "Late IO16" function.
Normal IO16 is the default setting for most PCs.
This sets the board for standard 16-Bit "AT compatible" bus timing.
Late IO16 is an optional setting that makes the board timing compatible with PCs using VLSI
chips, IBM PS/2 Model 30 computer using VLSI chips.
SW1-3 is used to select the data transport mode:
Set SW1-3 to "OFF" to select the "I/O mode" (default setting).
SW1-3's "ON" position is reserved for future use.
If your computer is equipped with a LAN status LED on its front panel, jumper JP1 can be used
to connect to the LED to indicate the LAN station's activity.
