VMIVME-2120* Specifications 64-bit High Voltage Digital Output with Built-in-Test
Functional Characteristics
Compatibility: VMEbus specification compatible. Double height form factor.
Output Connector Type: Dual 64-pin connectors – DIN 41612
Output Organization: Eight ports, eight bits wide. Addressable to any address within short supervisory or short nonprivileged I/O map. Control and Status Register (CSR) address is independently selectable.
Address Modifier Codes: Jumper-selectable for short supervisory or short nonprivileged I/O access. Factory configured for short supervisory I/O access.
Addressing Scheme: Eight ports individually addressable on 8-, 16-, or 32-bit boundaries. The separate board address decoder for the CSR allows addresses for hardware control to be grouped for improved software efficiency.
Data Transfer Bus: A16: D8, D16, D32
Built-in-Test: This product supports off-line and real-time fault detection and isolation. The off-line mode is enabled by executing a write to the CSR to set the Test Mode Bit. All outputs are OFF with the Test Mode enabled.
Fail LED: A Fail LED is provided that is illuminated at powerup and extinguished under program control upon successful diagnostic execution.
Output Drivers: This product may be ordered with a variety of output driver options as shown in the Ordering Options. As the Ordering Options show, the board can be manufactured with (1) automatic surge current shutdown protection, (2) no shutdown protection, or (3) thermal shutdown protection for driving incandescent lamps. A detailed description is provided on page 6 for options (1) and (2). The thermal shutdown protection for driving incandescent lamps (3) is described on page 6.
Output Features: The high current driver (600mA sink) outputs are designed to drive incandescent lamps and inductive loads without external current limiting or warming resistors. Due to cold filament inrush currents, it is recommended that only one lamp be driven by the output driver. However, if more than one bulb must be driven by a single wire, then another driver must be connected in parallel. If more than one bulb must be driven by a single output, it is recommended the VMIVME-2131* (current source/sink) or the VMIVME-2130* (current source only) be used if the application will allow. The output drivers of the VMIVME-2131 and VMIVME-2130 will not necessarily support all of the VMIVME-2120* current sink (open collector) applications. In addition to this, the VMIVME-2120 and VMIVME-213x have dissimilar power requirements.
