IEEE 1284 SERIAL TO PARALLEL CONVERTER
5. Operation
Once the Converter is properly configured and installed, it should operate transparently—as if it were a standard cable connection. There is no ON/OFF switch.
LED Status Monitors
The Converter features two easy-to-read status LEDs. The green LED glows when optional AC power (from the optional PS095 power supply) is applied to the unit. The red LED indicator blinks to show data activity. Since there is only one indicator, it uses different LED codes to demonstrate various messages. The following chart describes these codes.
