PC Serial Port Stepper Motor Interface Card (24V)
Click here for specs, downloads and more pictures.

Features:

  • PC Serial Port Stepper Motor Interface Card
  • NOW MUCH FASTER - Up to 6.3kHz Stepping Rates
  • SIMULTANEOUS MOTOR CONTROL ADDED
  • Connects to the PC serial port and provides an easy to use interface for connecting and controlling stepper motors by your PC. You can multidrop up to 4 interface cards off the 1 RS232 serial line so you can control up to a total of 16 stepper motors.

You simply write ascii commands through the PC's serial port to the card to control each of the stepper motors. A free PC program (source code in VB is included) is provided so that you can execute a number of commands and repeat the process.

Parallel Port Interface with Relays Card Kit 24V
Click here for specs, downloads and more pictures.
Our Parallel Port Relay card allows you to control stepper motor operations
from your parallel port. It uses a 74HC245 buffer IC to provide protection
for your PC’s parallel port and provide enough current drive for turning on
and off opto-isolator inputs. Can be connected to our KTA-191, KTA-196 and KTA-179 stepper motor driver cards. The card provides 8 motor control output signals ( 4 Step signals, 4 Direction signals) to control up to 4 Stepper Motor Drivers, 4 digital inputs designed for use as limit switch inputs, 2 Relay Outputs to control spindles, coolant or vacuums, and 3 general IO which are connected directly to the port. The card is available with 12V or 24V relays and requires power at the relay voltage.  Fitted with screw terminals. Perfect for a 3 axis or 4 axis CNC machine.
You can also use it in other applications for I/O control from your parallel port
Finished Dimensions (mm): 58Wx88Lx25H

Available as KTA-205 (12V Powered) or KTB-205 (24V Powered)

Spyder-PLC-UART-DC
Click here for specs, downloads, and more pictures.
Description: Based on the feedback of previous generations, This new third-generation powerline communication modem product consists of a PLC-UART motherboard, a UART-RS232 daughter board, a UART-RS485 daughter board, a UART-USB daughter board, and a UART-Ethernet daughter board.On the PLC-UART motherboard, there is a 20-pin receptacle, users can choose different daughter boards based on the interface needs. This 20-pin receptacle is pin-compatible with Xbee module from Digi (http://www.digi.com/). So an Xbee module can also be used on PLC-UART, and PLC-UART will become a powerline communication to a Zigbee bridge.

Bluetooth Modem - BlueSMiRF Gold
Click here for specs, downloads, and more pictures.
Description: The BlueSMiRF is the latest Bluetooth wireless serial cable replacement! These modems work as a serial (RX/TX) pipe. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target. We've tested these units successfully over open air at 350ft (106m)!

The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.

Unit comes without a connector. Please see related male and female pins below.

Dimensions: 51.5x15.8x5.6mm

McLaren HS-PLC-UART Hi-Speed Powerline Communication PLC-UART
Click here for specs, downloads, and more pictures.
NEW - LOWER PRICE!
Price was: $88.11

Description: A broadband powerline communication module (5Mbps throughput on the powerline). Based on the feedback received on the narrow band powerline communication modem, broadband modems consist of a PLC-UART motherboard, with a UART-RS232 daughter board, a UART-RS485 daughter board, a UART-USB daughter board, a UART-Zigbee daughter board, or a UART-Ethernet daughter board. 

NOTE: User manual update: No need to have a CD for software.  The software is simply a serial port debugger. We recommend X-CTU (click on the picture to get to  a page with the links).
