Silex technology SX-560 manual GPIO=00abLF

GPIO set message format

This message may be optionally sent by the remote computer when an E-GPIO connection is active. This message allows the remote computer to set the state for any GPIO pins configured as outputs. This is equivalent to the SET GPIO DATA command.

The message is in the format:

GPIO=00ab<LF>

Where ab are 2 hex digits representing the state of the GPIO pins. Since there are only 8 GPIO pins on the SX-560, the first two digits should always be 0. Any other message sent to the E- GPIO connection is ignored. If the message is formatted incorrectly, it is ignored.

Example:

Local> set gpio mon en

Local> set gpio addr 192.168.1.100

Local> set gpio port 9999

Local> set gpio poll 100

Local> sh gpio mon

E-GPIO mode Enabled

E-Cable destination 192.168.1.100

Poll interval 100 milliseconds

Not connected

Table 26 GPIO SNMP Management

The GPIO pins can also be managed via SNMP. The available MIB items are described in this section. The GPIO related MIB items are in the Silex private MIB, and the GPIO tree is at gpio=enterprises.1240.2.3.4.9.

GPIO bit mask

Integer read-only gpio.1

This is an integer representing a bit mask indicating what GPIO pins are available. There is a 1 for each GPIO pin that is present. For the SX-560, this value is 255 (xFF), indicating 8 GPIO pins.
