Product Description

The Dual Programmable Timer (TMI-2001) is a PCI local bus controller with two independent program-controlled timers. Each timer can be programmed to generate a PCI local bus interrupt at the completion of the selected time interval.

Two pulse timer output signals are provided for user connection to external equipment. The outputs can be programmed for positive or negative polarity and pulse width duration. Each pulse timer can be coupled with an interval timer to generate a repeating pulse that occurs whenever the internal timer overflows.

Two user input signals are also available for generation of one or two PCI local bus interrupts from an external source(s). The input signals can be programmed for positive or negative edge detection.

An OpenVMS device driver provides the application interface to the TMI-2001. Source code is supplied to accommodate the possible need for user modification of the driver to support a unique application.

Two Independent Timers
Each timer can be independently programmed for an interval ranging from 50 microseconds to over 214 seconds in increments of 50 nanoseconds.

Two User Output Signals
One output signal is provided from each pulse timer for user connection to external equipment. The two output signals are user programmable for a pulse width from 100 nanoseconds to 3.276 milliseconds in increments of 50 nanoseconds and are available to the user from an on-board DE9 connector.

Two User Input Signals
Two user input signals are provided for generation of one or two PCI local bus interrupts from external sources. The two input signals are user programmable and are available to the user from an on-board mounted DE9 connector.

Easy to maintain. A module exerciser supplied with any purchased device driver allows the user to verify TMI-2001 operation.
