2.2.8 Card Edge Connector (X7)
Figure 15: Card Edge Connector X7
The Card Edge Connector at X7 is a PHYTEC development connector and allows other custom
expansion boards or DIN rail bus modules to be connected. The connector can be used as a
RS485 or CAN interface, depending on the position of jumpers J5 and J6 (
section 2.1.4
).
As there exists no standard, pay close attention to the pin assignment shown in
Table 13
.

Table 13: Pin Assignment of CardEdge Connector X7
If the phyBOARD-Regor is supplied via the card edge connector, there is no
protection against overcurrent through fuse F1.
