Installation of COM7 and COM8

If you want to activate the (optional) interfaces COM7 and COM8 first fix the

chip (see illustration). Please take care that the position point (terminal) on

the chip shows to the back of the board. Then plug the connector of the

male/female connectors as shown in the illustration below. Now you can

secure the connectors (male/female), which are fitted to a cover, to the

marked recess on the housing using the screws provided.

The sockets or connectors for the COM7/COM8 as well as the chip are not

part of the COM board delivery unit. They can be ordered separately.
