The RTU functions as a remote terminal that is under the complete control of a host PC or other computer device and commnicates message text and commands in standard ASCII format via Ethernet, RS-485, or RS-232.  It may be used with a magstripe or RFID proximity card-reader.  Card-data and/or keypresses are automatically transmitted to any host PC or computer device.  Pre-formatted ASCII data received from the host will be displayed on the LCD.

The heart of the system is a Rabbit Semiconductor OP6700 programmable terminal with 4x20 line LCD display, 12-key membrane keypad with relegendable keys. Rabbit Semiconductor is a renowned manufacturer of high-quality, affordable single-board computers and related products. Click here for more information on the programmable terminal.

The RTU offers features found in the higher end products, but at a fraction of the cost.  How do we do it?  The answer is simple - no overhead.  You save big $$$ by purchasing the terminal unit(s) directly from the supplier.  Some assembly may be required depending on the hardware configuration desired.  For instance, a keypad-access configuration with no card-readers will require almost no assembly and will be the most economical.  Or, you may choose to add one or even two card-readers.  Once you've assembled the unit, we provide firmware programming for a nominal fee. 

The RTU features a number of access options including barcode reader, proximity reader, and magstripe reader.  If desired, card-readers may be excluded, allowing the system to be used in keypad-access mode - the most economical solution.

The RTU also accepts special host commands.  These commands perform functions such as terminal configuration and setup.  The RTU can also accept a command to activate or deactivate its onboard output driver.  Suitable for controlling a small external relay, this output can be used in a variety of applications including gate activation, process control, alarm activation, etc.  The open-collector output can sink up to 40VDC @ 200mA.

Optional host application software provides access to the RTU from your Windows PC.  Great for monitoring and/or testing.  Send pre-constructed messages to the terminal and receive terminal responses.  Includes auto-detect feature and firmware upgrade utility.

The system is customizable to suit your needs.
