4.2 V.35EU Serial I/O Card
The V.35EU (European Union version) Serial I/O card and its single port adhere
strictly to the V.35 standard. Unlike the V.35H Serial I/O card, which uses
alternate means to achieve V.35 signaling, the V.35EU Serial I/O card uses
specified electrical levels for control, timing and data signals and also uses an M-
34 block connector for connection to external devices.
4.2.1 V.35EU Serial I/O Card Components
Important components on the V.35EU Serial I/O Card include:
• edge connector
• port connector
• signal LEDs
• port configuration jumper
The edge connector fixes the card to any one of the motherboard’s expansion slots
1-8.
The connector plate fixes the female M-34 block connector to the chassis’ rear
panel with two Phillips-head screws and limits dust accumulation and
electromagnetic radiation.
