System 50 NETWORK INTERFACES ProMux® (Optomux) FEATURES • Each Board Controls Up to 24 Standard, Mini, G5 or OpenLine® Digital Modules • Up to 256 Addressable ProMux® Boards Separated by 4,000 Feet • 100% Optomux Compatible, Plus Extra Commands • Communications at Speeds From 300 Baud to 38.4 KBaud. • Transient Protection on Communications Lines • Direct Plug-In or Ribbon Cable Interconnection • BASIC and C Drivers for the PC APPLICATIONS Stand Alone Control Local Control & I/O Remote I/O Distributed I/O SCADA RTU System 50 DIGITAL INPUTS/OUTPUTS ® The ProMux network interface mates with any of our 8, 16, or 24 digital module racks. Plug Grayhill OpenLine®, standard, miniature, or G5 digital I/O modules into the racks. They can be mixed in any combination. Connect the ProMux® boards serially to a host computer 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 SOFTWARE • • • • Count pulses at frequencies up to 400Hz Detect rising or falling edges Latch momentary input events Turn outputs ON or OFF individually or in groups • Pulse-width modulate outputs • Provide delayed-on or delayed-off outputs • Generate pulses or squarewaves Software drivers are available which simplify the task of interfacing programs written in Visual Basic or C to the ProMux® network. 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 COMMUNICATIONS ® The host computer and ProMux boards 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 and response messages. Application programs running on the host computer issue commands and then await responses from the ProMux ® boards. The 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. All ProMux® boards are thoroughly tested and 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.
