Latch logic of the count values
Asynchronous latch individually for each channel by software, encoder reference mark or external signal
Synchronous latch of several channel by software, timer or external signal
Output signal for cascading several cards; can be programmed for software sync or timer sync.
Counter operating modes
Three counter channels (32 bits each) with one load and two latch registers
Counting of encoder square-wave signals with one-fold, two-fold or four-fold evaluation
Event counter with direction and clear input
Integral timer for measuring the pulse widths, the frequency and the velocity.
PC bus
PCI connector, 5 V, 32-bit, 2 x 60 pins
Target interface (slave) as per specifications Rev. 2.1
Current consumption at +5 V approx. 0.,5 A, without encoders
Power supply of the encoders:
+5 V or +12 V from PCI power supply
(current consumption depends on encoders connected)
Counter interface (X1)
Nine RS 422 or. TTL inputs for three encoders with square-wave signals and reference mark
Maximum input frequency
5 MHz with delta signals (Line Driver RS 422 standard)
2 MHz with single-end signals
Perceives edge distances up to 80 ns
One TTL input for interfering-signal monitoring
Separate power supply lines for each encoder
I/O interface (X2)
Six inputs (3 to 30 V) that can be used as reference pulse inhibitors or as asynchronous latch signals
One input (3 to 30 V) for synchronous latch of several channels
One output (TTL) for cascading several cards
Software
DLL (Dynamic Link Library) for operation with Windows 95/98/ME and NT
VxD driver for Windows 95/98/ME
Sys driver for Windows NT
Test and demo software with sample programs
Mechanical design and environment
Dimensions (of the PCB) approx. 120 x 92 mm width = one slot
Maximum permissible ambient temperature +40°C
One D-sub female terminal strip, 25-pin for the counter inputs
One D-sub female terminal strip, 9-pin for the for I/O-signalsEinspeicher-Logik der Zδhlerwerte
