1098 QPC513 Enhanced Serial Data Interface card
Synchronous port address space is the same as asynchronous port address
space. When selecting an address for the ESDI card, make sure that it does
not conflict with an address currently being used by an asynchronous card.
Table447 "ESDI card address switch settings" (page 1098) shows the ESDI
card address switch settings.

DTE/DCE mode jumper settings
The interface foreach ESDI por t is configuredindependently. Ports must be
configured both for electrical interface (RS-232-C or high-speed) and mode
(DTE or DCE). With the proper options set:
•An ESDI port configured as DTE appears as a terminal to the user
equipment.
•An ESDI port configured as DCE appears as a modem to the user
equipment.
Interface options are set by installing option jumper plugs into the sockets
indicated in Table448 "ESDI card DTE/DCE mode jumper settings" (page
1099) and Table449 "ESDI card RS-232-C/high-speed interface jumper
settings" (page 1100).
