Features

The following brief overview of principal features illustrates the flexibility and

performance that is available with the VMIVME-3113A Board:

• 64 differential or single-ended inputs

• Powers up in AUTOSCANNING MODE - no software initialization required

• Continually digitizes all input channels and stores the results in a dedicated

channel dual-port register (AUTOSCANNING MODE)

• Six operating modes

— AUTOSCANNING MODE *

— RANDOM POLL MODE

— RANDOM INTERRUPT MODE

— SCANNING POLL MODE

— SCANNING INTERRUPT MODE

— AUTOSCANNING MODE with BIT

* Only for gain = 1 and a minimum of 16 channels.

• VMEbus interrupts may be programmed to interrupt upon completion of a

single A/D conversion, or upon completion of a 16 through 64-channel scan

(see “Analog-to-Digital (ADC) Control and Timing” on page 26)

• User-programmable interval timer supports scanning of all channels at periodic intervals

• Jumper-programmable gains of 1, 10, 100, 200 and 500

• Selectable A/D ranges of 0 to +10V, ±5V and ±10V

• Low-level and high-level inputs: ±10mV to ±10V

• Optional low pass filter

• Overvoltage protected inputs

• 5 x 106

Ω input impedance differential and 2x106

Ω input impedance

single-ended

• 33 kHz conversion rate at GAIN<500 (23kHz for GAIN = 500)

• Selectable output code: binary, offset binary, two's complement with sign extension

• Front panel Fail LED is under program control and may be used for any purpose

• Board ID register

The VMIVME-5576 does not need to be initialized unless interrupts are used.

If interrupts are used, vectors and interrupt levels must be written to on-board registers and interrupts must be set.

Each node on the system has a unique identification number between 0 and 255.

The node number is determined by placing jumpers on the board during hardware system integration.

The node number can be read by software by accessing the on-board registers. 

In some applications, the node number helps determine the function of the node.

The IS200SAMBH1A is an acoustic monitoring terminal board that is part of the GE Speedtronic Mark VI gas turbine controller.
