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).

R.E.Smith I/O Commander (no plug-ins required!)

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.

Model ICSX7HV, 3.0KV ISOLATED 7-PORT RS485 REPEATER with
RS232 PORT:

This unit can be connected to a computers’ RS232 port, and distribute RS485
via 7 Isolated Ports to form large/robust networks. Units can be cascaded for
very large RS485 multi-drop (2-wire, half-duplex) networks.

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.

Model IHV24XT (3.0KV) and IRSFC24XT (1.5KV)
Opto/Xformer Isolated Intelligent RS232 to RS485 Converters (Replacements
for the Model IRSFC24T):

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!
