PC Serial Port Stepper Motor Interface Card (24V)

(Full Documentation in pdf Format) 

Examples of the commands are:

    @01 AMOV 1000 2000 n 4000  do an absolute move of stepper 1,2 and 4 to positions 1000, 2000 and 4000
    @01 AMOV 2000  do an absolute move of stepper 1 to position 2000
    @02 RMOV -400  do a relative move of stepper 2 400 steps backwards
    @03 POSN 10000   indicate stepper 3 is at position 1000
    @04 STOP  stop stepper 4
    @01 STAT   card sends the status of motors 1 to 4 whether they are moving or not and status of limit switches.

Positions can be between -99999999 and 99999999 steps. The user can also set the acceleration and deceleration rates when starting and ending a sequence of steps. Limit switch inputs are available for each of the motors to prevent motors moving out of range.

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.

Serial Isolated I/O Module (kit)
 
8-Relay Module (mains rated - 110V and 250VAC.) An extension of our Kit CPS74 (see next kit), PC controlled 8-Relay Board with 250V switching relays and added features. It is in a plastic case, latched relay operation, 250V relays switched in safety by using Dinkle connectors, and with 4 external inputs. Uses serial port so it can be located over 100 yards from the PC. Comes with case and end panel pieces as shown in the photos. Requires a center positive 9-to-12V DC power supply, at least 500mA, 2.5mm jack. (CPS108)

Upgrade K108 - join two k108 together
 
CPS108/CPA108 has been a good seller. This kit is to connect two of them together to give 6 Inputs and 16 Relay Outputs. All you have to do is change the firmware, change the front & back panels, and jumper out 2 ICs.

PC Printer Port Relay Board (Assembled) (version 2)
 
Do you have an old PC lying around the house which absolutely no one wants? Then you can convert it into a dedicated controller. Communicate with the real world via the parallel printer port on your PC. Simply connect a DB25 straight trough cable from computer to DB25 connector on the relay board. There are 8 relays each capable of switching 12VDC/10A or 240VAC/5A. Each relay has an LED to indicate when it is operated. We provide two sets of complete, stand-alone software to control the relays: one works under DOS so you can write your own batch files to control individual relays, the other works under Windows. Needs 12VDC center positive 2.5mm power supply. PCB Size 6.75" x 2.75" (CPA74)
