Standalone Programming Operation (no PC) |
|
|
The ISPnano programmer is capable of operating in ‘Standalone Mode’ i.e. without PC Control. In this mode a single 'Programming Project' or a set of 'Chained Projects' can be triggered using an external event. The programmer can be triggered to start a programming sequence using any of the following methods:
• [START] button on front panel
• 4-wire TTL Remote control Port (Ideal for ATE Remote Control)
• Target 'Load Sensing' Detection
• Test Fixture 'Lid Switch Sensing' (closes to start programming)
• Remote Keypad / Display mounted on the top of the Test Fixture
