LEDs and General Purpose IO Signals
The LEDs are connected to the 10 GPIOs for easy viewing of signal activity. The first 7 GPIOs drive the
first 7 LEDs, D4 to D10 (these LEDs indicate the status of the GPIOs). The last 3 GPIOs 8 to 10 drive
LEDs D1 to D3. Logic 0 and 0 volts on GPIO_x illuminates the LED.
RS-232 Cable
The supplied DB-9 female-to-female null modem cable is wired as shown below. The pinouts are
compatible with a standard PC 9-pin serial connector, so this cable can be used to directly connect a PC
to Serial Port 2 for use as a console terminal to configure the SX-550. It can also be used to connect
many types of OEM serial devices to Serial Port 1, provided that these devices use PC-compatible 9-pin
connectors.
