APPLICATIONS

DIGITAL INPUTS/OUTPUTS

The ProMux

any of our 8, 16, or 24 digital module racks.

Plug Grayhill OpenLine

or G5 digital I/O modules into the racks. They

can be mixed in any combination. Connect the

ProMux

and then issue commands to monitor the

inputs or control the outputs. Commands are

included which permit you to:

• Read the ON/OFF status of inputs

• Determine the width of input pulses

System 50

• Count pulses at frequencies up to 400Hz

• Detect rising or falling edges

• Latch momentary input events

• Turn outputs ON or OFF individually or in

• Pulse-width modulate outputs

• Provide delayed-on or delayed-off outputs

• Generate pulses or squarewaves

COMMUNICATIONS

The host computer and ProMux

communicate serially over two pair of twisted

wires per RS-422/485 in either a multi-drop or

repeat configuration. They use an industry

standard ASCII string format to code the

command

Application programs running on the host

computer issue commands and then await

responses from the ProMux

communications speed is selectable between

300 baud and 38.4 KBaud. Each controller on

the network is assigned a unique base address

from 0 to 255. You can separate boards from

one another by as much as 4,000 feet.

SOFTWARE

Software drivers are available which simplify

the task of interfacing programs written in

Visual Basic or C to the ProMux

Sample programs and the set-up and debug

utilities are included on the disk with the drivers.

Interface drivers for most third party software

packages are available through their

distributors.

OTHER FEATURES

All ProMux

shipped in static proof boxes.

Because space inside your enclosure can be

limited, we offer numerous rack plug-in

configuration options. For applications requiring

even more mounting flexibility, the ProMux

boards can be connected to racks with a

ribbon cable up to six feet long.

If you do not have an RS-422 or RS-485 serial

port on your PC, we offer a variety of RS-232

to RS-422/485 converters (see page L-103)

“Communications Converters” for technical

and ordering information.
