Introduction
Thank you for your purchase of the ADC VelociGraph, the most advanced high-speed
chronograph available. Every effort has been made to ensure that your new VelociGraph is a
high-quality, easy to use precision instrument. This Operation Manual contains instructions
for setting up your VelociGraph and configuring it for your application.
Your VelociGraph might have features not described in this documentation. If your
VelociGraph is marked as a custom order, please be sure to see any additional documentation
included with the unit after reading through this manual.
The VelociGraph VG03 captures high-speed pulses from external sensors (typically an ADC
iBeam Sensor, or other light-screen sensor), calculates the time between those pulses and, if
configured to do so, the speed of the projectile that passed through the sensors. Data is
available via the RS485 serial port built into the device using a custom protocol.
The VG03 is designed to be integrated easily with an ADC iBeam sensor system, but can
accept any pulse 0.5 milliseconds or with a voltage range of 5-24VDC without any need for
configuration. In short, the VelociGraph VG03 can be integrated with almost any sensor
available.
The VG03 is typically used for capturing the speed of a projectile, but has been used for
other applications, as well. Because of its adaptability and the ease at which it can be used
with other software, the uses of the VG03 are limitless.
The VG03 has four inputs, but can be networked with other VG03 units to handle large
sensor installations.
The VG03 operates at 80 MHz
