3-Pin Terminal Block Power Connector
Mainboard power is applied to the FR201 platform by way of a 3-pin terminal block connector (Mating
part: Dinkle 2ESSM-03P
current of the connector is 15A per pin. Use a wire gauge that is rated for the operational current. See
below for on-board connector pinout.
Note: DC power input should not be connected when the system is supplied with POE power via the
ADP122 add-on module.
5-Pin COM Terminal Block
The serial port supports RS-232, RS-422, and RS-485 configurations by way of a 5-pin terminal block
connector (Mating part: Dinkle 0221-2005 or equivalent). The mode can be selected from within the
operating system using available configuration tools. See FR201 software documentation for details.
LAN1 - CM4 output
The CM4 LAN Port on FR201 supports up to 1Gbps link speeds over standard shielded CAT5e or
CAT6 cables. The connector is the industry standard RJ45 connector. The LAN link state is shown by
the two LEDs enclosed in the port. Activity is also indicated by the LAN1 LED on the side of the
equivalent). The system is operational from 8V~24V. The maximum rated
