5.1 Common Information for the OPTE3/E5 and OPTE2/E8 Option Boards
5.1.1 The OPTE3/E5 and OPTE2/E8 Option Board Layout
The fieldbus is connected to the OPTE3 and OPTE2 option boards using a 5-pin pluggable bus connector. The fieldbus is connected
to the OPTE5 and OPTE8 option boards using a Sub- D9 connector. The option boards have the same layout regarding connectors,
LEDs and jumpers. The following figure shows the board layout. OPTE5 and OPTE8 use a different fieldbus connector.
