This is the same idea as the TW523P, except it is designed to run on the serial port of your PC. DB25 connect. Very popular unit, outsells the parallel unit by 50:1. Requires a TW523 and a cable to work. May not work on some laptops because of their low power output. Circuit board inside connector. Not RS232, but passes through bits sent from the TW523. Will not(hmmm maybe) work under windows. Works excellent under DOS. Can transmit and receive X-10 signals. Source code supplied in "C", BASIC, PASCALPricing:
