OUTPUTS
Each analogue output has two serial relays that switch the output signal to one of two ways, the direct or the
inverse. If not activate any of the relays, both outputs (the direct and inverse) are disconnected.
OUTPUT PWM1
The connections of the output 1 are through 4 pole terminal plug, with the follow pin assignment:
Output 1 connector
Pin Name
VPP1
GND1
VO1
VR1
OUTPUT PWM2
The connections of the output 1 are through 4 pole terminal plug, with the follow pin assignment:
Output 2 connector
Pin name
VPP2
GND2
VO2

ISP (PROGRAMACION "IN CIRCUIT" / "IN SYSTEM")
The expansion has a connector to record "In-System" (eg. Microprocessor software update). This connector has
10 pins:
