PCI Express 8‑channel 32‑bit high‑speed up/down counter board. Supports 10 MHz pulse input with differential line receiver or TTL input. Disconnection detection for differential inputs. Bus master transfer, digital filter, and synchronous control connectors for multi‑board operation.
8‑Channel 32‑Bit
High‑Speed Counter
The CNT32‑8M‑PE provides eight 32‑bit up/down counter channels on a PCI Express board. It accepts differential line receiver or TTL‑level inputs up to 10 MHz. Supports 2‑phase (quadrature) or single‑phase counting. Features bus master transfer for high‑speed data sampling and synchronous control connectors for multi‑board operation.
- 8 independent 32‑bit counters
- 10 MHz max input frequency
- Differential or TTL input (software select)
- Disconnection detection (differential)
- Varistor surge protection
- Bus master transfer (80 MB/s)
- 1K‑DWord FIFO
- Digital filter (0.1µs – 1.6384ms)
- Synchronous control (16 boards)
- General‑purpose timer
Synchronous operation — sync control connectors (CN2, CN3) allow up to 16 boards to operate synchronously with a single master board. Included synchronization cable (10cm).
Built for Precision Counting
-
High speed — 10 MHz max input frequency; supports differential line receiver (up to 1200m) and TTL input.
-
Disconnection detection — detects cable disconnection for differential line receiver inputs.
-
Digital filter — programmable per channel (0.1 µsec to 1.6384 msec) to reject noise.
-
Control input — one per channel for start/stop/preset/zero‑clear; software‑selectable.
-
Count match — generate interrupt or output one‑shot pulse when count matches preset value.
-
Synchronous control — up to 16 boards with master/slave configuration.
-
Varistor protection — input circuit protected from voltage surges.

-
Control inputs — DI0‑DI7 (preset/zero‑clear/start/stop/general), EXTSTART, EXTSTOP, EXTCLK.
-
Control outputs — DO0‑DO7 (match/error/general/one‑shot), test pulse outputs.
-
Sync connectors — CN2 and CN3 for connecting multiple boards (included cable: 10cm).
-
Optional cables — PCB69PS/PCB69P (96‑pin shielded/flat), PCA69PS/PCA69P (one‑end).
-
Terminal boards — EPD‑96A (M3 × 96), EPD‑96, DTP‑64A.
