DEVICE DIP Switches
The 8-position AxLink DEVICE DIP switch sets the AxLink identification number for your AxLink device.
Make sure the device number matches the number assigned in the software program. The following table
describes the values on the AxLink DEVICE DIP switch.
If the device’s value is set to 0 (by positioning all DIP switches to the OFF setting), you can use AxLink serial
commands with your AxLink device.
RS232
The RS232 control port is a bi-directional serial port. The port uses a 3-pin 3.5mm Phoenix connector, and
supports 9600 baud communications only. When communicating via RS-232, connect the wiring as shown in
FIG. 15.
The following table lists the default button commands when you connect an SP-08-AX 8-Button Keypad:
