The KD-RTU6x00 Remote Terminal Unit (RTU) is a low-cost terminal that features keypad, LCD display, RS-232, RS-485 (KD-RTU6600), Ethernet (KD-RTU6700), and your selection of optional reader: magstripe, barcode, and/or proximity reader.
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.
