Microcontroller Programmer Overview and Description
The base unit of the programmer contains two LEDs. The red LED is marked program or device power and is lit whenever power is applied to device sockets. The green LED is marked power and indicates that the base is turned on. This LED should turn on approximately three seconds after power is supplied to the programmer.
Do not insert or remove devices from the programmer while the red program (device power) LED is lit!
On the front edge of the programmer base is a black banana plug receptacle. This is attached to the safety ground of the power cord in order to assist you in connecting to electrostatic protection equipment.
