Working principle
Functional components: mainly including VMEbus interface, analog-to-digital converter (ADC) and control logic, analog input multiplexing, gain and conversion, BIT voltage reference and multiplexer, board ID register and other functional parts.
VMEbus interface: Communication registers are mapped to 64 16 bit words (128 bytes) in memory, which can be located on any 128 byte boundary within the VMEbus short I/O space and can be configured to respond to short monitoring or short non privileged data access.
Analog to digital conversion control and timing: There are two operating modes, namely continuous scanning of all 16 or 32 analog input channels, and stopping scanning and locking to a single channel. Using a 12 bit ADC with a conversion time of 8.5 μ sec, the channel acquisition cycle is once every 25 μ sec, and the total scanning rate is 40 kHz. The ADC’s built-in tracking and holding device can prevent erroneous readings from signals that change during the conversion cycle.
Built in Test Reference: Equipped with programmable precision voltage reference for board built-in testing (BIT). When selected, the BIT voltage is fed to the ADC through a programmable gain amplifier, bypassing the external analog input on channel 0. Users can enable BIT during initial board installation or real-time system self diagnosis.
Analog Input: The front panel connector provides 16 differential or 32 single ended analog inputs. It is recommended to use differential mode to reduce noise and improve common mode rejection ratio. Unused inputs should be grounded, and the low end of the differential input on the board has an internal 22 M Ω pull-down resistor.
Low pass filter: Provides a passive single pole low-pass input filter with a normal -3 dB cut-off frequency of 50 kHz, and can also be configured with an additional sub board to provide a low-pass filter with a cut-off frequency of 40 Hz.
Input multiplexer: There are two levels of analog multiplexing, with each of the 32 inputs selected through one of the four 8×1 first level analog input multiplexers. The second level multiplexer is configured as a 4×2 board, and one or two of the first level output signals are selected to provide single ended or differential operation mode. BIT reference voltage can also be selected.
Programmable gain instrumentation amplifier: After selecting the input channel and passing through the input multiplexer, it enters the programmable gain amplifier as a differential input. The differential amplifier suppresses common mode noise and delivers the scaled single ended output to the ADC. The hardware can jumper the gain to 1, 10, and 100.
Channel sequencer and dual port RAM memory: typically run in scan mode, starting conversion immediately after power on or reset. After A/D conversion is completed, the dual port control logic retrieves the conversion data and stores it in the corresponding dual port register of the channel. The channel counter increments and selects the next channel to be multiplexed to the ADC. After all input channels are converted and stored, the channel counter resets and starts the channel scanning sequence again. The channel sequencer can be stopped at the current address by the stop auto scan bit in the control/status register.
Board ID Register: The first position of the VMIVME-3125 register group is the read-only board ID register, with a value of $37, used for general system software to automatically determine the installed board.
Built in power converter and ADC power supply: The power supply for the analog circuit is provided by an onboard DC-DC converter, which converts the+5 VDC of VMEbus to a regulated ± 15 VDC. The+5 VDC logic power supply for the ADC is provided by an onboard regulator, and a separate+5 V DC-DC converter is used to provide isolated analog ground for the ADC.
Configuration and Installation
Unpacking procedure: Components may be sensitive to electrostatic discharge. When handling, the board should be placed on conductive material. After unpacking, check for any transportation damage. If there is any damage, file a claim with the carrier and report to GE.
Physical installation: Power off installation, insert the board into the appropriate slot of the chassis, ensure correct alignment and orientation, smoothly slide towards the mating connector until firmly seated.
Jumper installation
Board address: occupies a short I/O address space of 128 consecutive bytes, with the base address controlled by jumper E6 to E14. The installed jumper corresponds to binary 0, and the uninstalled one corresponds to binary 1. The factory default address is short I/O $0000 (all jumper installations).
Address modifier: Jumper E16 determines the access mode of the response, including monitoring, non privileged, or both.
Input configuration: Three jumpers (J4, J5, and E5) are used to configure single ended or differential inputs, two jumpers (E1 and E2) control the input voltage range, two jumpers (E3 and E4) control the gain, and there are filter related jumpers. The factory default configuration is single ended, ± 10 V range, and unity gain.
Analog input connector description: 16 differential or 32 single ended analog input connections are made through the front panel 37 pin D-type connector P3, with corresponding pins and signal allocation.
Calibration Procedure: To obtain the specified accuracy of analog measurements, calibration is required for the required range and input topology. Firstly, instrument amplifier offset and BIT voltage calibration are performed, and then the corresponding offset and gain calibration procedures for the input topology are selected. Calibration requires a 5-digit digital voltmeter (DVM) and precision voltage reference equipment.
Programming
Memory mapping: occupying 128 bytes of address space, including four information and control registers, as well as a conversion data register. Depending on the jumper configuration of the board (single ended or differential input, normal or maximum buffer for differential input), there are different memory mapping tables.
Register description
Board ID register: 8-bit read-only register, offset $00, value $37, used to uniquely identify the board.
Configuration register: 8-bit read-only register, offset $01, indicating the current configuration, including input mode and filter bandwidth information.
Control/Status Register: 8-bit read/write register with an offset of $02, allowing software to control the board and indicate its current status, including functions such as stopping automatic scanning, maximum buffer, complement, mode bit, LED off, etc.
Channel pointer register: an 8-bit read-only register with an offset of $03, typically storing the input channel number currently being sampled and converted. Under specific configurations, it can determine the most recently updated data register.
Data registers: Depending on the state of the maximum buffer location, there are 16 or 32 data registers. Starting from an offset of $40, each 12 bit conversion data containing its related channel is aligned to the right within the 16 bit data register.
Built in testing function: It can test the function by applying various internal reference voltages to channel 0 input. The host software can read the value of channel 0 and compare it with the expected value. There are corresponding BIT value tables for different ranges and gain settings.
Range and gain determination: The analog gain and range can be set by the user, but the software cannot directly read these settings. It is not recommended to determine the current settings through BIT voltage stimulation, as the board must be calibrated to a single gain and range setting.
Accessing data in byte form: Data registers should typically be accessed using a single 16 bit word transfer, or two consecutive byte transfers, but there is a risk of confusion caused by data updates, which can be avoided by pausing automatic scanning or ensuring that byte accesses are continuous and undisturbed.
Current input options: VMIVME-3125-200 and VMIVME-3125-300 offer different terminal resistances, and the ADC input voltage is related to the current range, allowing for the calculation of the current signal through a formula.

VMIVME-5565 is a member of the VMIC Reflective Memory Real time Fiber Network product series based on VMEbus. It adopts a standard 6U European card shape and can be integrated with VMIMPC-5565 and VMIPCI-5565 of the same series into networks using standard fiber optic cables. Each card in the network is called a node. It enables computers, workstations, PLCs, and other embedded controllers with different architectures and operating systems to share data in real time, with convenient operation. Data is transmitted through written memory (SDRAM), and the onboard circuit automatically transfers the data to all other nodes, almost without the involvement of any host processor or system.

Standardize compliance
Compliant with the VMEbus specification (ANSI/IEEE STD 1014-1987, IEC 821 and 297), with the relevant mnemonics A32: A24; D32/D16/D08 (EO): Slave: 39/3D:09/0D。
Working principle
Basic operation: Each node in the network is interconnected in a daisy chain loop through fiber optic cables. The data transmission is initiated by the VMEbus host system writing to the onboard SDRAM. During the writing process, the onboard circuit automatically writes the data and related information into the transmit FIFO, which then forms variable length data packets ranging from 4 to 64 bytes. These packets are transmitted through the fiber optic interface to the receiver of the next board. After receiving, the relevant circuit opens the data packet and stores it in the receiving FIFO, then writes it to the corresponding position of the local onboard SDRAM, and routes the data to its own sending FIFO. This process is repeated until the data returns to the source node and is removed.
Front panel LED indicator lights: There are three LED indicator lights, with the bottom red being the status indicator light. When powered on, it defaults to “ON” and the status can be switched by writing to bit 31 of the control and status registers; The yellow color in the middle is the signal detection indicator light, which is “ON” when the receiver detects light; The green light at the top is the self data indicator light, which is “ON” when detecting the return of self data.
Register group: including Universe II registers (specific control and status and DMA control registers located in the VMEbus bridge, byte order in small end mode) and Reflective Memory (RFM) control and status registers (implementing unique features of the 5565 series reflective memory board).
Reflective memory RAM: available in two sizes of 64 Mbytes or 128 Mbytes, with parity check function. The parity check function is not enabled when powered on and needs to be enabled through a specific bit setting. When enabled, only 32-bit or 64 bit writes are allowed.
Interrupt circuit: There is a programmable VMEbus interrupt output, and the interrupt source can be separately enabled and monitored through the local interrupt status register (LISR) and local interrupt enable register (LIER).
Network Interruption: capable of transmitting interrupt packets on the network, which can be directed to specific nodes or broadcasted to all nodes, including sender node ID, destination node ID, interrupt type information, and 32-bit user-defined data. The receiving node will store the relevant information in the corresponding FIFO.
Redundant transmission mode: configured through jumper E5, each data packet is transmitted twice in redundant mode, and the receiving node evaluates the transmission situation. Although this mode reduces the probability of data loss, it will lower the effective network transmission rate.
Abnormal packet removal operation: Abnormal packets refer to packets that do not belong to any node in the network. VMIVME-5565 can work as one of the two abnormal master nodes. When an abnormal packet is detected, it will be removed from the ring and relevant flag bits will be set.
Byte order: Due to the tradition of different microprocessor manufacturers, there is a distinction between big endian and small endian. The PCI to VMEbus interface of VMIVME-5565 uses Intel or equivalent bridge chips, adopts small endian byte order, and the interface has external byte order conversion logic, which can achieve independent master/slave hardware byte order conversion.
Configuration and Installation
Unpacking program: Components may be sensitive to electrostatic discharge, so attention should be paid when handling them. After unpacking, check for any damage.
Switch/jumper configuration and position
Node ID Switch (S6): An 8-bit switch that sets the node ID within the range of 0 to 255. Each node ID must be unique, and the switch position “ON” corresponds to 0, while “OFF” corresponds to 1.
Jumper E5 (redundant mode configuration): Used to configure redundant or non redundant transmission modes and select abnormal master nodes, with different pin hopping states corresponding to different functions.
Register and memory configuration switch: VMIVME-5565 occupies two independent address spaces on VMEbus. The control and status register spaces can be set as extended address space (A32) or standard address space (A24), and the SDRAM memory space can be set as extended address space (A32). When configuring, address overlap should be avoided. The switch “ON” corresponds to address bit 0, and “OFF” corresponds to address bit 1.
Physical installation: Power off installation, ensure correct switch settings, fix after installation on the chassis, and connect fiber optic cables according to the ring topology.
Front panel description: Optical transceiver, “RX” for receiver, “TX” for transmitter, using “LC” type fiber optic cable, with three LED indicator lights as described earlier. When operating, pay attention to dust prevention and avoid looking directly at the transmitter.
Cable configuration: There are multi-mode or single mode fiber optic interfaces, and cables and connectors have specific specifications.
Connectivity: Nodes are connected in a circular manner.
