Overview

The Aitech C430 (Multi I/O 6U VME Slave board) provides up to 192 I/Os from three sets of digital I/O
circuits. The first set has 32 differential I/O channels that can be configured to 64 TTL I/O channels under
software control. The second set has 64 TTL channels that can be configured as input or output under
software control. The third set has 8 High-side MOSFET switches, 8 Low-side MOSFET switches, and 6
sets of 8 isolated Low-side MOSFET switches with an independent return line.

The C430 provides maximum flexibility and ease of use allowing customization to specific requirements. All differential and TTL I/Os are protected against high transient voltage. The differential I/Os are RS-485
compliant and are compatible with TIA/EIA-422-B. The TTL I/Os used have high drive capability (-15mA
IOH, 64mA IOL).

The C430 is compatible with VMEbus Specification. The VME interface support A24/D32 data transfers.
VME Base address can be set in one of two methods:
• Using the on board jumpers
• Using geographical address pins on P2 connector
The C430 is available both in commercial and rugged configurations. The rugged board is available in both
air-cooled and conduction-cooled version.
