Direction of connect B+K PRECISION ISP
programmer to target system:
The recommendation for design of target
system with ISP programmed device
1. Turn off both devices – ISP programmer and target device.
2. Assign same GND potential for all devices, e.g. connect GND
3. Insert one connector of ISP cable to ISP programmer, turn on
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
7. After direction of control program, disconnect other ISP cable
8. If you need another action on target device, you continue with

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.
The target system must be designed to allow all signals, which
are use for In-system programming to be directly connected to
ISP programmer via ISP connector. If target system use these
signals for other function, is necessary isolated these signals.
Target system mustn’t affect these signals during In-system
programming.
For in-system programmable devices manufacturers publish
applications notes. Design of B+K PRECISION programmers
together with respect of these application notes allows proper
In-system programming. Condition is exactly respect these
application notes Allocations notes, which B+K PRECISION

step 5.
Purpose of D1 diode is to protect the target circuit against a
higher voltage, which is provided by ISP programmer.
If your target board supply differs from mentioned 5V,
choose please the Zener diode (D1) voltage according to
this supply voltage.
We recommend using resistors R1, R2, (R3) to separate
the target device from target system. If pins needed for ISP
