The CIO-CTR05 and CTR10 are 5 and 10-channel counter timer boards for IBM PC and compatible computers. The boards employs a 9513 counter/timer chip, providing five counters with 16-bit count registers (the CIO-CTR10 has two 9513 chips). The 9513 is an extremely powerful and flexible component, software programmable for event counting, pulse and frequency measurement, alarm comparator and other input functions. As an output device, the 9513 can generate frequencies with complex duty cycles and provide one-shot and continuous outputs.
The 9513 counter may be chained together via software, enabling, in the CIO-CTR05, a 16, 32, 40 or 48-bit counter to be constructed within the chip. In the CIO-CTR10, a 32, 48, 64 or 80-bit counter may be constructed. In addition, the gate source and gating functions are software programmable.
The CIO-CTR05 also has 8/8 digital inputs/outputs, while the CIO-CTR10 has 16/16 digital inputs/outputs. The digital outputs may be used to switch solid state relays and the digital input port may be used to sense contact closures. Access to the PC bus interrupts is provided via two interrupt jumpers. A 1 MHz crystal on board supplies a precise source of timing pulses.
Cabling and Connection
Cabling to the boards is via standard 37-pin D connector. The CIO-CTR05 has one connector,
while the CIO-CTR10 has two. Each connector cable carries all counter
inputs, outputs and gates for one 9513, 16 digital lines, +5 V and ground. Each is CTM-05
compatible.
Software
The CIO-CTR boards are supplied with Instacal, a test and setup program. Programmers may purchase
an optional UNIVERSAL DRIVER package for most popular Dos and Windows programming languages for $49.
