Functional Features

Compatibility: Compatible with VMEbus specification.

Double height form factor.

Output Connector Type: Dual 64-pin connector DIN 41612.

Output Organisation Eight ports, eight bits wide.

Addressable to any address within the Short-Circuit Monitor or Short-Circuit Unprivileged I/O map. Control and Status Register (CSR) addresses are independently selectable.

Address Modifier Codes: Short-circuit supervisory or short-circuit unprivileged I/O access can be selected via jumpers.

Factory configured for short-supervised I/O access.

Addressing Scheme: Eight ports can be individually addressed on 8-bit, 16-bit, or 32-bit boundaries.

CSR's separate board address decoder allows hardware control addresses to be grouped for software efficiency.

Data Transfer Bus: A16: D8. D16. D32

Built-in Test: This product supports offline and real-time fault detection and isolation. Offline mode can be enabled by writing the CSR Set Test Mode bit.

When test mode is enabled, all outputs are off. When test mode is enabled, all outputs are off.

Fault LED: The Fault LED is illuminated at power-up and extinguished under program control after a successful diagnostic.

Output Functions: High current driver (600 mA sink current) outputs designed to drive incandescent lamps and inductive loads.

No external current limiting or warm-up resistors are required. Due to the presence of cold filament inrush currents, it is recommended that the output driver drive only one lamp.

However, if a single wire must drive more than one lamp, another driver must be connected in parallel.

If a single output must drive more than one bulb, it is recommended that the VMIVME-2131 (current source/sink)

or VMIVME-2130 (current source only) if the application allows.

The output drivers of the VMIVME-2131 and VMIVME-2130 may not support all VMIVME-2120 current sink (open collector) applications.

In addition, the power supply requirements for the VMIVME-2120 and VMIVME-213x are different.
