2.9 PCMCIA: PC Card Slot

The UNO-2059E provides one PC Card slot that supports CardBus

(Card-32) Card and 16-bit (PCMCIA 2.1/JEIDA 4.2) Card standard. It

supports +3.3 V, +5 V and +12 V @ 120 mA working voltage.

PC Card is a 85.6 mm long by 54 mm wide (3.37" x 2.126") sized, 68-pin

connector used and removable module standardized by PCMCIA that is

known as “PCMCIA card.”

PS: PCMCIA interrupt assignment is IRQ 9.

2.10 VGA: VGA Display Connector

The UNO-2059E provides a VGA controller for a high resolution VGA

interface. It supports VGA and VESA, up to 1280 x 1024 @ 8 bpp and

1024 x 768 @ 24bpp resolution and up to 16 MB share memory. The

VGA interface is reserved for system testing and debugging. The UNO-

2059E's JP8 is a 6-pin mini connector and CN7 is a 15-pin connector for a

VGA monitor. A VGA cable is attached to convert from a 6-pin mini con-

nector to standard VGA connector. You can choose one of VGA inter-

faces for system testing and debugging. Pin assignments for VGA display

are detailed in Appendix A.8.

2.11 Programmable LED & Buzzer

In headless application (an application without monitor display), it is

always a big problem to know the system status. Another PC may be

needed to monitor headless device status via RS-232 or Ethernet. In order

to solve this problem, UNO-2059E offers a programmable LED indicator

and buzzer. Hence, they can be programmed to show a system’s status by

LED indicator flickering and buzzer alarm.
