In keeping with Caliper Designs tradition of maintaining compatibility with
evolving technologies, CDI developed PCI-ScaleTrack to allow current PC’s to be
connected to all encoder systems.
3 Axis.
Over 4.0 MHz count rate.
Computer powered adaptors for all incremental encoder types.
Renishaw touch probe circuitry- built in. Latches all 3 axis.
Separate event triggers for latching each axis.
8 bit output port, and 8 bit input port for machine control.
Software development kit included.
Wide support among software vendors.
PCI-ScaleTrack is one of the fastest quadrature counting systems
available. Using PCI-ScaleTrack, systems can keep up with a quadrature signal
with state changes as often as every 250 NS (4.0 MHz). PCI-ScaleTrack has a
common internal event latch which can be used for touch probes or foot
switches.
PCI-ScaleTrack also has individual event latches for each axis which can
be used for index mark inputs. In addition PCI-ScaleTrack contains an 8 bit
output port and a separate 8 bit input port. All these controls can be
accessed by a proprietary DLL, which is included.
Needless to say, PCI-ScaleTrack can accommodate most encoder counting and
positioning tasks.

Software Development Kit
The software development kit included with each card so that you can get started
immediately. This kit provides:
A sample program written in VB -
Header and Library files for use with C and C++ programming.
Electrical
PCI ScaleTrack is designed using surface mount LSI technology resulting in fewer
parts and better reliability.
Power requirements; +5VDC, +/-12VDC obtained from CPU
Power is provided on the 50 pin I/O connector for powering adaptor boxes or
connecting directly to square wave encoders.
Computer power available; +5VDC, +/-12VDC (fused @ 2A)
Count rate is approximately 4.8MHZ
Connects to external system via 50 pin D-sub female connector
Power supply connections are available on the 50 pin output connector for scale
and interface power. The +5 connections are not fused. The +/- 12 volt
connections are fused at 2 amps. Connection to PCI-ScaleTrack is exactly the
same as connecting to our legacy ISA counter card. PCI-ScaleTrack connects to
all our interface units allowing PCI-ScaleTrack to be connected to any encoder
technology.
Mechanical
PCI-ScaleTrack is housed on one PCI format 4 layer printed circuit board.
PCI-ScaleTrack measures 6.875in (175MM) long and is a standard height at 4.2in
(107mm)
PCI-ScaleTrack is the latest counter card available from Caliper Designs, Inc.
PCI-ScaleTrack is engineered to directly interface to all of Caliper Designs
interpolators and interfaces.
PCI-ScaleTrack connects directly to existing touch probes, and can keep up with
a quadrature signal generating state changes every 800ns (1.2mhz count rate).
PCI-ScaleTrack accepts TTL level, single ended quadrature signals from any
source. This allows a 25 foot capability without an adaptor.
