R. E. Smith I/O Commander:

Version 3P1a (3-16-2002) of the "R.E. Smith I/O Commander" is now available for download.

The I/O Commander is designed to communicate , test and control our line of digital and analog I/O products. However, due to its flexible nature, it can also be used as a general purpose terminal emulator (color coded TXD/RXD and, split screen modes) and, as a drum sequencer. The terminal emulator now supports COM1 through COM8, and data rates from 300bps to 230.2Kbps.

Download RescomdrV2P6a.exe software for Windows 95, 98, ME, 2000, XP and NT (Does NOT require installation).

The I/O Commander builds and uses small text files to send commands and receive responses from target devices on a serial port (drum sequencer). Since getting started may be a little confusing, we have some sample.txt files in the future that will allow the user to make modifications at will. Call for additional information.

We would appreciate any comments or suggestions during this development phase.

R. E. Smith SuperCas Software (for our line of Code Activated Switches):

Version 2P1a (8-12-2001) of the "R.E. Smith SuperCas" software is now available for download. We have several new products that allow "networking" RS232 devices over an RS485/RS422/Fiber Optic/Ethernet Serial Server "backbone." These Code Activated Switches are addressable and very flexible. The CAS24 is a single RS232 switch port and, the ICASX4 has 4 addressable RS232 switched ports with an isolated RS485 "backbone." The FCASX3 has 2 addressable RS232 switched ports and, one switched port that can be RS232 or Isolated RS485 and operates over a Fiber Optic "backbone." The CAS232X8 is a 1 of 8 RS232 software selectable switch (connect 8 RS232 devices to one RS242 port on your PC). Please call for additional information. The ESPSX3 is an Ethernet Serial Port Server with 3 buffered RS232 com ports (one port can be Isolated RS485/RS422). Use this software for all CAS products.

R. E. Smith CAS24 Software (Code Activated Switch RS485/422 to RS232):

Original version (3-3-2001) of the "R.E. Smith CAS24" software is now available for download. The CAS24 can be used to network several (250+) RS232 devices over an RS485/RS422 network. Use the SuperCAS version above to take advantage of all the features of the CAS24 board. For reference only.

R. E. Smith CAT-5 Converters(SS Series) and RS232 "Extension Cords":

The SS (super simple) series of Converters have a minimum number of configuration jumpers and, in general will allow RS485/RS422 connections using Category-5 cable. Some models can even supply power to a remote converter over the Cat-5 cable. These units should NOT be connected to the Ethernet.

The Model IHV24XT Converter is an "industrial strength" unit with Intelligent Detection and Display of Internal/External Error Conditions. This converter provides an onboard microprocessor and 5 LED indicators to help identify problems during installation and normal operation. This unit offers dual transient protection in addition to the 3.0KV isolation. The unit operates from 9-35VDC. Operating speed is 300-115.2Kbps with a "Fast Automatic Transmitt Enable Circuit." The IHV24XT will also operate as a "standard" converter with display of data activity (TXD/RXD) on the RS485 side of the interface. Call for additional information. Units are available off-the shelf. If you can find a more robust/flexible, "high speed" automatic converter, than the IHV24XT please let us know!
