GE VMIVME-2510B 64 bit TTL digital I/O board

GE VMIVME-2510B 64 bit TTL digital I/O board

Main features of the product

The direction of each 8-bit port can be individually programmed.

Capable of injecting 64mA current.

The control register and data register use independent board address decoding.

Built in testing (BIT) logic for fault detection and isolation.

Equipped with fault LED indicator light.

Compatible with VMIC's intelligent I/O controller product line.

Adopting high reliability DIN type I/O connectors.

Supports 8-bit, 16 bit, and 32-bit data transmission.

Optional open electrode output.

Functional characteristics

Compatibility: Complies with VMEbus specifications and adopts dual height external dimensions.

I/O connector type: Dual 64 pin DIN connector.

I/O organization: 8 I/O ports, each 8 bits wide, addressable to any address within a short monitoring or short non privileged I/O mapping.

Addressing scheme: 8 ports can be individually addressed on 8-bit or 16 bit boundaries, and address DIP switches provide unlimited short data I/O address mapping options.

Built in testing: Output data can be read back in real-time or in offline mode. Offline mode is enabled by writing to the control and status register (CSR) to set the test mode bit. When the test mode is enabled, all outputs are in three states, providing two test mode bits. If necessary, each connector's I/O (32-bit) can be independently tested.

Fault LED: It lights up during power startup and system reset, and can be turned off after successful diagnosis under program control.

I/O circuit: The transceiver supports high current input (64mA) output, and the logic level TTL I/O option uses the SN74AS645 octal bus transceiver. The open collector electrode option uses the SN74AS641 transceiver. If the open collector electrode option is ordered, all 64 bits are only output.

Product model: There are multiple models of this product, with 2510 being the original design (one test mode bit); 2510A has two test mode bits (one for each connector); 2510B is recommended for new designs (two test mode bits).

Ordering Options

A (input/output type and data polarity): 1 is TTL logic level input and output, positive logic; 2 is TTL logic level input and output, negative logic; 3 is an open electrode output (no input), positive logic; 4 is an open electrode output (no input) with negative logic.

B (output resistance): 0 is an uninstalled resistor; 1 is 2.2k Ω (open collector electrode input/output must be selected).

C. D and E: 0 are unused.

Positive/negative logic ordering information

TTL I/O: The positive logic input option presents a high-level input voltage on each data line corresponding to logic 1 on VMEbus; The positive logic output option presents logic 1 to the output data register (ODR), presenting a high-level output voltage on each data line. The negative logic input option presents a high-level input voltage on each data line corresponding to logic 0 on VMEbus; The negative logic output option presents a logic 0 to the output data register and a high-level output voltage on each data line.

Open collector electrode output option: The positive logic output option presents logic 1 to the ODR (the corresponding bit on VMEbus is logic 1), causing the output open collector electrode transistor to conduct and provide grounding for the load; The negative logic output option presents logic 0 to the ODR (with the corresponding bit on VMEbus being logic 1), causing the open collector electrode output transistor to turn off.

IIOC compatibility

This product is compatible with VMIC's Intelligent I/O Controller (IIOC) series and is suitable for fields such as data acquisition, process control, factory automation, as well as simulation and training markets. The IIOC software supports the I/O of this product, allowing users to load the direction of I/O on each connector offline. Therefore, IIOC does not support separate port control, and its support is limited to VMIVME-2510A or -2510B models. IIOC is a multiprocessor controller that includes a CPU, global memory, various optional host interfaces, and firmware, providing a complete I/O solution.
