2.4 CONNECTORS
Connector
:
It allows to connect the ground (GNDE) of the external
power supply to the ground (PE).
Connector
XS
It allows to connect the ground (PE) to the DeviceNet
cable shield.
Terminal
BUS
See the figure below. It allows to connect the SBI board
to the DeviceNet network. The pins are the following:

2.5 DIP SWITCHES
S3
Interrupt selection from selector S5 (INT1/INT2) to the microcontroller 8032 or
to the interrupt input of the dual port ram (INTR). Default position is A (interrupt
to the dual port ram).
S4
Synchronisation connection for the reset signal of the SBI board to the con-
nected regulation board. Default position is ON.
S5
It is used to connect the signal INT_OPZ to the signal INT1 (S5.B) or to the
signal INT2 (S5.A). The interface board is standard set as OPTION 1, therefore
INT_OPZ is connected to the signal INT1. (Default position is A).
S6
It is used to connect the signal OUT_OPZ to the signal OUT1 (S6.A) or OUT2
(S6.B). Default position is B.
S7
It is used to connect the signal CEM_OPZ to the signal OPZ1 (S7.B) or to the
signal OPZ2 (S7.A). The SBI board is standard set as OPTION 1, therefore
CEM_OPZ is connected to the signal OPZ1. Default position is B.
S8
Connection of the dual port ram BUSY signal to the signal RDY_EXT. Default
position is ON.
