 QPC513 Enhanced Serial Data Interface card
Configuring the ESDI card
Configuring the ESDI card consists of setting the port addresses using the 
address selection switch and setting the port interface options using the 
jumper blocks. The system software must then be configured to recognize the 
ESDI card. Figure 182 on 
 shows the location of all option switches 
and jumper sockets on the ESDI card.
Address switch settings
The two ESDI ports on the card are addressed in pairs such as 0 and 1, 2 and 
3, and so on). The address is set using switch S2. The switch settings used to 
select the address vary depending on whether the card is Style A or Style B. 
The “Style” can be read on the printed circuit board silk screen. The address 
of the card is set to match the device address defined in software. 
Synchronous port address space is the same as asynchronous port address 
space. When selecting an address for the ESDI card, make sure that it will not 
conflict with an address currently being used by an asynchronous card.
Table 265 shows the ESDI card address switch settings.
