Overview

The WBK20A is a PCMCIA/EPP Interface Card. Together, the card and associated cable provide a PC

with an EPP port by way of the computer’s PCMCIA slot.

The WBK20A typically has a data rate of 600 K to 1000 Kbytes/sec, or in terms of samples, 300 K to

500 K samples/sec [since 2 bytes is equal to 1 sample]. Although the WBK20A is capable of higher rates,

these are seldom realized because of such factors as: PC architecture, operating system, available

resources, and software implementation.

The earlier WBK20 and EPPCard/1 function the same as the WBK20A. The difference in

the devices is that the WBK20A uses cable CA-191-1, which has a locking cable connector;

whereas the earlier devices use a non-locking cable (CA-157-1). The two cable types cannot

be interchanged.

The WBK20A is not a “Hot-Swap” card. To ensure proper operation of the WBK20A card,

boot up the computer only after verifying that the WBK20A is inserted in the PC’s card slot.

Failure to do so may prevent the application software from recognizing the card as a

parallel port device.

Windows NT does not support the WBK20 or the WBK20A.
