1.10.11 LAN1, LAN2 ports
The device contains 2 x LAN ports.
LAN1 port supports 10/100 Mbit/s operation modes and is based on Intel WGI210IT controller. The
LAN2 port supports 10/100 Mbit operation modes and is implemented on the basis of a controller
built into the Vortex86DX3 microprocessor.
The ports provide galvanic isolation up to 500 V (each port is individually isolated from the system).
The LAN ports are routed to a single XP1 connector: IDC2-16, 16-pin two-row
Each port is routed to a two-row 10-pin connector with a pitch of 2 mm, 98414-G06-10LF (FCI). 10-
pin socket 89947-710LF (FCI) for a flat ribbon cable with a pitch of 1 mm or a 10-pin socket
10073599-010LF (FCI) with pins 77138-101LF (FCI).

1.10.12 RTC, SPI FRAM, lithium battery
The device is equipped with an AT-compatible real-time clock with an installed CR2032 lithium
battery with a capacity of 200 mAh. The battery is installed into the XS3 socket located on the back
of the board. Battery service life is decreased at high and low ambient temperatures, in case of a
high degree of contamination of the
module’s PCB, as well as when the module is in the off state
for a long time. The average service life is 4 to 10 years.
Important note!
If the device is turned off for a long time, it is recommended to synchronize the real-time clock with
the exact time readings.
FRAM nonvolatile memory with the serial SPI interface is designed to save the SETUP BIOS copy
and restore the RTC memory state in case of an error.
