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, split screen modes, and 32/1024 "hot-keys") and, as a drum sequencer. The terminal emulator now supports COM1 through COMX, and data rates from 300bps to 921.6Kbps. Now with flow control and parity. Same low cost: Free

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 (for 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.

Model ICSX7HV, 3.0KV ISOLATED 7-PORT RS485
REPEATER with RS232 PORT:
(Isolated Communications Spider - "Let me spin a very large RS485 network for you!")
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.

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!
