The transistor drives the set of three LEDs to form a light source. When no data exists on the RS-232C port, the LEDs remain off. When data transmission takes place, the LEDs glow at the rate of the ...
Tristate-buffer 74HC244 multiplexes 8 bits of A/D-converter data through 4 bits (54 through 57) of the status port of the printer adapter. This design does not require an external power supply, ...
A clever way to consolidate enough power from the TX data and handshake lines on an RS-232C port to run a small circuit. The typical RS232 transceiver interface IC found in many embedded systems ...
Features include the company’s SX Virtual Link Serial Port Emulation, an industry-standard DB-9M RS-232C port, auto sensing, and an exclusive auto-find and setup utility. Pricing is $99 each.
An RS-232C port means that this unit is well equipped to work with the "big boys" and makes it suitable for use by custom installers using AMX or Crestron systems (among others). Users can visit the ...
