J576 AIM104-VGA-CRT 2192-08800-000-000 AIM104-VGA-CRT Introduction The AIM104-VGA-CRT is a high performance Super VGA graphics PC/104 form factor board for use with PC/104 based processor systems. This product is based around the CIRRUS LOGIC GD5429 True Colour VGA controller. Features � 8/16 bit PC-104 interface. � Hardware and BIOS compatibility with IBM S-VGA display standards. � Supports a wide range of colour CRT monitors. Connection is made using the industry standard 15-pin high density D-type connector, or as a build option an �alternative� 16 way IDC ribbon connector. � �Green PC� power-saving features. � VESA advanced feature connector (VAFC) for video overlay and colour key support for use in Multi- Media applications. � 32K byte BIOS ROM. � 1MB of on-board video memory fitted as standard. � Standard module supports graphics modes up to 1280 x 1024 (interlaced) in 16 colours, 1024 x 768 in 256 colours (non-interlaced 8 bits/pixel), 800 x 600 in 64K colours (non-interlaced 16 bit/pixel) and 640 x 480 in 16M colours (non-interlaced 24 bits/pixel). � Extended text modes up to 132 columns by 43 rows. � Support of zero wait state option for faster operation. � �End of active field� interrupt implemented on IRQ9. � 5V only operation. � Power consumption from host max. 200mA @+5V. � Operating temperature range -20 to +70�C. � MTBF: 492,362 hours (using generic figures from MIL-HDBK-217F at ground benign). Operation The AIM104-VGA-CRT is intended to be used as the sole video board in a PC/104 based system using either a PC/AT compatible processor board such as Arcom�s SBC104, or Arcom�s TARGET processor boards TARGET188EB and TARGET386EX. Using the AIM104-VGA-CRT with Arcom�s TARGET processors requires some modifications to the Target Board Firmware - For details of these changes refer to Arcom Product Note No. 27. The AIM104-VGA-CRT will drive a wide range of colour and monochrome IBM compatible monitors including standard VGA fixed frequency analogue and multi-frequency (Multisync) monitors. In addition to being 100% IBM VGA compatible the AIM104-VGA-CRT BIOS complies fully with VESA video modes and specifications. Software written to use VESA video modes will run without the need to install extra drivers. Electromagnetic Compatability (EMC) The AIM104-VGA-CRT is classified as a �component� with regard to the European Community EMC regulations and it is the users responsibility to ensure that systems using the board are compliant with the appropriate EMC standards. If the electronic system requires input protection against high voltage transients (to meet CE requirements) it is recommended that an external interface board is located at the point where the external wiring enters the electronic system enclosure.

Once located in the platform processor PC/104 stack, plug the high density D-type connector from the monitor into the mating half, PL2, on the AIM104-VGA-CRT. Switching-on Switch the monitor on and then switch the system on. The monitor will display light-grey text on a black background as the system goes through its boot sequence. Link positioning Default link position diagram The AIM104-VGA-CRT has three link selectable options. Throughout this section �+� indicates a default link setting. + Fitted, Adaptor asserts IRQ9 on pin B4 of PL4 at the end of an active field. LK1- Omitted, IRQ9 is not asserted. + Fitted, Zero Wait State video memory accesses are supported. LK2- Omitted, No Zero Wait State video memory accesses. + Fitted, Casing of PL2 is connected to System Chassis Ground. LK3- Omitted, No connection is made between System Chassis Ground and PL2. Note- Fitting/Omitting LK3 may reduce interference effects of System Ground loops.

This contains Cirrus Logic�s utility program CLMODE and the display drivers required by Microsoft Windows 3.1 to support higher text and graphics resolutions. Installing Utilities and Drivers under Windows 3.1 Windows 3.1 users need to install the GD5429 display drivers. With Windows running on your machine, run the installation program INSTALL.EXE from the diskette supplied. Using the AIM104-VGA-CRT under Windows �95 and Windows NT Windows �95 and Windows NT users are able to auto-detect new hardware. Your Windows �95/NT disks should contain the necessary drivers for the CL-GD5429. W Wi in n � �9 95 5 - The display drivers for the AIM104-VGA-CRT are installed simply by using the Add New Hardware Wizard in the Control Panel Program Folder. This allows auto-detection and installation of drivers for new hardware. W Wi in n N NT T - Windows NT runs a Hardware Auto-detect at start-up which should recognise the AIM104- VGA-CRT and the CL-GD5429 controller. CLMODE Selecting the correct monitor refresh rates will allow the AIM104-VGA-CRT to display the highest quality video with the attached monitor. The CLMODE utility allows the user to define the monitor type attached and set the video modes supported by the AIM104-VGA-CRT. After running the installation program from the utilities disk provided, CLMODE.EXE can be found in the directory C C::\ \W WIIN ND DO OW WS S\ \V VG GA AU UT TIIL L. To use this utility correctly, follow the on screen instuctions and the help feature. CLMODE is a DOS based program, and cannot be executed under Windows.
