The circuit above also shows how to interface with an open collector output from another device.
Reading the inputs is accomplished by sending the unit an io get command, as shown below.
/1 io get di
@01 0 OK IDLE –- 0 0 1 0 /1 io get di 1
@01 0 OK IDLE -- 0
The first command queries all inputs on the device and shows that input 3 is high and all others
are low. The second command queries a specific input on the device, in this case input 1, which is
low.
