Hardware Overview
Front and Back Panel Inputs/Outputs

VR10500 Hardware Manual2
Hardware Overview CONTINUED
· The three Gigabit Ethernet ports each operate up to 1,000Mbps. The UPLINK
port connects to the workstation computer, and the two expansion ports
connect to additional controllers for higher channel count systems. The ports
support auto-negotiation, full duplex, and flow control. They also support auto
MDXoperation to eliminate any requirements for crossover network cables.
· The front panel has16 BNC input connectors that support various analog input
devices including accelerometers, microphones, and external conditioners.
Each input channel supports single ended and capacitor coupled operation for
IEPE transducers and smart transducers (TEDS). Each channel includes
support for multiple input voltage ranges:
Input Voltage Range

0-20V peak
100 kΩ
±10V peak
100 kΩ
±1V peak
100 kΩ
±5V peak
10 MΩ
±0.5V peak
10 MΩ
· The rear panel has four BNC output connectors that support various analog
drive devices up to ±10V. For single-axis control, the DRIVE 1 port is typically
used to drive an amplifier or servo-hydraulic controller. The AUXport is
typically used to support synchronization with constant level adapter (COLA)
devices such as stroboscopes or data acquisition devices. The DRIVE 2 and
DRIVE 3 ports can be used for multi-shaker control or as additional
AUX/COLA channels. Pairs of outputs can be used to support differential
mode output.
· The digital drive output interface has two additional drive signals. They can be
used in conjunction with the four analog drive signals for six channels of
DRIVE/AUX/COLA or separately for two remote drive outputs. The digital drive
interface has several advantages over the traditional analog drive interface,
including longer cable lengths without signal degradation and higher immunity
to low and high frequency electrical noise. A separate unit is typically required
to convert the digital drive signal into an analog signal that can drive a
standard amplifier input. This unit would be located near the input to the
amplifier or servo-hydraulic controller.
· The rear panel has an interbox port for loop synchronization of multiple
VR10500 units. Loop sync can be completed with hardware or software
clocks. Hardware clocks via interbox connection are only recommended for
systems with more than 48 input channels.

[e-mail]
· The rear panel has an AUXinputs/outputs DB37 connector that supports eight
digital outputs and eight analog/digital inputs. They can be used to integrate
with other systems or to monitor analog signals. The DB37 connector can
also support a tachometer.
System Ventilation Fan
The VR10500 has one fan for system ventilation. Make sure the fan and vent
openings remain unobstructed to allow for proper airflow.

connecting the power cable to the amplifier's controller outlet. No operator
settings are required for voltage configuration.
· After connecting the VR10500 to a power source, confirm that the device is
connected and operating correctly by examining the LEDs on the front panel.
· The standard AC power cable is the primary disconnecting device. Position
the equipment so that it is easy to disconnect the AC power cord.
100/1000BASE-T CABLE REQUIREMENTS
All category 5 UTP cables used for 100BASE-TX connections also operate with
1000BASE-T provided that all four wire pairs are connected. However, it is
recommended that an enhanced category 5e or newer cable is used for all
critical connections or any new cable installations. The category 5e or newer
specification includes test parameters that are only recommended for category 5
and comply with the IEEE 802.3ab standards.
The VR10500 supports auto-detection of straight through and crossed cables on
all switching 10/100/1000BASE-T ports. The automatic correction of errors in
cable selection makes the distinction between a straight through cable and a
crossover cable irrelevant.

Remote I/O
CAUTION: Terminals provided on the unit shall be connected only to passive
load transducers or source transducers that apply no more than 10V to the
circuit that originates from the VR10500 (or a value that equates to not more
than 33Vac RMS/46.7V peak or 70Vdc total on the circuit).
CAUTION: Other than the IEC inlet for input power to the unit, terminals
provided on the rear of the unit shall be connected only to SELV/double
insulated circuits of other equipment.
BNC Inputs and Outputs
BNC connectors are manufactured with 50Ω and 75Ω impedance capability. 50Ω
cables are typically used in this application. BNC inputs are typically used with
accelerometers. Nominal ranging allows for maximum 10V peak input devices.
BNC output ranging allows driving maximum 10V peak devices, including
COLA/AUX.
The BNC inputs support IEPE sensors by providing a current limited power
source that can be enabled and disabled through the software. When enabled, it
provides 4.4mA at up to 26VDC to power the sensor.
Power Connectors
The VR10500 is powered by the AC internal power supply.
Internal Power Supply Connector
The VR10500 supports a single internal power supply to provide power for
switching operations. The AC power connector is located on the back panel of
the hardware.
Interbox
The interbox interface on the back panel of the VR10500 supports
synchronization of multiple VR10500 units with greater accuracy than
synchronization with Ethernet connection alone. The interbox interface uses
standard Ethernet RJ-45 connectors and Ethernet pinout. The electrical signals
on this interface are different than Ethernet at 2.4V and up to 24mA.
The interbox interface operates using standard Ethernet cabling; however, this
interface must use shielded cabling.

VR10500 Hardware Manual14
Remote I/O CONTINUED
AUX Outputs/Inputs
The AUX outputs/inputs interface allows for data acquisition and control of
additional devices. This interface uses a standard DB37 connector and an AMP
5747375-2 (or equivalent) mating connector.
The pinout on the back of the VR10500 is displayed below.
AUX INPUTS
The eight AUXinputs can be used to read an analog signal up to ±12V at 16-bit
resolution or a digital TTL signal. AUX inputs should be referenced to
AGND/Analog Ground and are protected from transients up to ±30V. Digital input
signals must be greater than 2.2V to ensure they are registered high and less
than 0.6V to ensure they are registered low. Note, AUX inputs 1 and 2 also
support tachometer functionality as described in the proceeding text.

[e-mail]
TACHOMETER INPUTS
Logic Level Configuration ("Unfiltered")
The tachometer logic level configuration is generally used with sensors that
output a 5V or 3.3V digital signal. This interface uses the AUXinput 1 and 2
connections. Input signals in this configuration must be greater than 2.2V to
ensure they are registered high and less than 0.6V to ensure they are registered
low. Input signals may be up to 1MHz. The VR10500 supports quadrature
decoding by using both tachometer inputs simultaneously.
Zero Crossing Configuration ("Filtered")
The zero crossing configuration is generally used with variable reluctance
magnetic sensors. This interface uses the dedicated tachometer inputs. Input
signals in this configuration must be bipolar where the voltage swings above and
below ground and may be up to 1MHz. These inputs should be referenced to
DGND/Digital Ground and are protected from transients up to ±100V.
In this configuration, the VR10500 detects zero crossings in the negative-going
direction. Zero crossings will only be detected after the input signal exceeds a
positive-going "arming" voltage, which is selectable between three different
values:
· Arm when ~0V is exceeded
· Arm when ~200mV is exceeded
· Arm when adaptive* threshold is exceeded
*The adaptive threshold monitors the input signal level and adjusts to be
approximately 80% of the peak input voltage. At input signal levels less than
230mV peak, the adaptive threshold is fixed at approximately 45mV. At input
signal levels less than 30mV peak, the adaptive mode will not arm.

VR10500 Hardware Manual16
Remote I/O CONTINUED
AUX INPUT BIAS
This output supplies 5VDC at up to 0.15A and can be used to power external
circuitry such as signal conditioners and relay coils.
AUX OUTPUTS
AUX outputs are nominally 5V TTL voltage levels but can drive up to +24VDC at
0.5A when supplied with appropriate external power via the AUXpower
interfaces. AUXoutputs should be referenced to DGND/Digital Ground and are
protected from transients up to +26.5V. The internal 5VDC power source can
supply up to 0.2A and is shared between the eight AUX outputs.
AUX output HIGH voltage (active):
· 4.5V minimum at 10mA source current
· 4.0V minimum at 200mA source current
AUX output LOW voltage (inactive):
· 0.3V maximum at 200mA sink current
· 0.8V maximum at 500mA sink current
AUX output OPEN
· 200kΩ to DGND/Digital Ground
NOTE: The AUX output drivers have a small pull-up leakage current (20uA
max) that may cause the voltage to drift above 0V when no load is connected.
AUX POWER
The AUX power interfaces accept an external DC power supply and allow the
AUX outputs to drive higher voltages and currents up to +24VDC at 0.5A per
output. The eight AUXoutputs are divided into two groups where AUXPWR_A is
associated with AUX outputs 1 to 4 and AUXPWR_B is associated with AUX
outputs 5 to 8. The two AUXPWR groups may be powered independently of each
other. Exceeding +26VDC on the AUXpower interfaces may permanently
damage the VR10500.
For example, AUXoutputs 1 to 4 could be configured for +12VDC operation by
connecting an external 12VDC power source between the AUXPWR_A pin and
DGND/Digital Ground, and AUXoutputs 5 to 8 could be left at 5VDC operation
by leaving the AUXPWR_B pin disconnected. The +12VDC external power
source would need to be capable of supplying enough current to drive all loads
connected to AUXoutputs 1 to 4.
