Connector description
The connectors used at the FroboBox is the industrial connector standard M12.
RS232 (M12 a-coded - 8pins female connector)
(8)+(9) on block diagram.
There are no configuration jumpers for COM1 and COM2 since they only operate in RS-232 mode.

RS232/422/485 (M12 a-coded - 8pins female connector)
(10)+(11) on block diagram.
Use CMOS Setup on the Versalogic mainboard to select between RS-232 4-wire, RS-422, and RS485 operating modes for COM3 and COM4. Jumper block V3 (see datasheet MEBX37-1.pdf for description) is used to enable the RS-422/485 termination resistor for COM3 and COM4. Jumper V3[1-2] enables the RS-422/485 termination resistor for COM3, and jumper V3[3-4] for COM4. The termination resistor should be enabled for RS-422 and the RS-485 endpoint station. It should be disabled for RS-232 and the RS-485 intermediate station.

Wifi/Bluetooth Antenna
The antenna for the Wifi and Bluetooth is identical. Looks like: TL-ANT2408CL from the company TP-Link. The antenna has a RP-SMA Male connection.

Scaffold
The internal scaffold for the FroboBox consists of three aluminum plates separated by 35 mm spacers. The lower plate is cut in shape to fit exactly into the enclosure and the two top plates are cut in dimensions 150 x 215 mm to fit the motherboard. When mounting the motherboard it is important to align it to the edge to make room for the RJ-45 connections. Get printable drawings of Top deck, middle deck and lower deck (A3).
Wirering
A splitter PCB is needed between the four serial connectors and the J18 connector on the motherboard. This can be done with the big and clumsy PCB that is delivered with the motherboard or with this nice and small PCB.
