eliminates the physical removal of chips from the system. This will save time and money, both
during development in the lab, and when updating the software or parameters in the field.
Target device is the device (microcontroller, PLD, etc…), which is to be in-system
programmed.
Target system is the physical Printed Circuit Board (PCB), which contains the device to be
in-system programmed.
ISP programmer is programmer, which has in-system programming capability (for example
866C, 866B, 844USB …).
General rules for in-system programming
We recommended respect following rules to avoid damage PC, ISP programmer, and target
device or target system:
• Ensure common earth point for target system, ISP programmer and PC.
• For laptop or other PC that is not connected to common earth point: make hard - wired
connection from laptop to common earth point (for example use LPT or COM port D –
connector).
• Any devices connected to target system must be connected to common earth point too.
Direction of connect B+K PRECISION ISP programmer to target
system:
During in-system programming you connect two electrical devices – ISP programmer and
target system. Unqualified connection can damage these devices.
Note: When you don’t keep below directions and you damage programmer during in-system
programming, it is damage of programmer by unqualified manipulation and is out of warranty.
1. Turn off both devices – ISP programmer and target device.
2. Assign same GND potential for all devices, e.g. connect GND of all devices by wire.
3. Insert one connector of ISP cable to ISP programmer, turn on programmer and control
program.
4. In control program select target device and operation options.
5. Start action on target device (read, program).
6. After direction of control program, connect other ISP cable connector to target system and
turn on it.
7. After direction of control program, disconnect other ISP cable connector from target system
and turn off it.
8. If you need another action on target device, you continue with step 5.
