Typical installation. 14 CHAPTER 4: Reading the LED 4. Reading the LED Once your Converter is properly configured and installed, it should operate transparently—as if it were a standard cable connection. Operating power is derived from the RS-232 data and control signals; there is no “ON/OFF” switch. The Converter indicates data activity by blinking. When the Converter has another message to report, the LED blinks according to the codes in Table 4-1 below. Table 4-1. LED Codes ••-•—••-•— Computer is sending data •—•—•— Serial device is connected; computer is not sendingdata ••—••— Both serial and parallel devices are connected; computer is not sending data •-•—•-•— Printer not ready, data held in buffer ••••—•••• Computer ignoring flow control, data lost Key: • Blink -Short pause — Long pause 15 SERIAL-PARALLEL CONVERTERS 5.
