OBU-352 has one Gigabit Ethernet port which supports 10/100/1000 Mbps connection.
It is suggested to use an Ethernet cable compatible with Cat5e or above standard for best
connection speed. The connector type should be RJ45 (TIA/EIA 568B).
The Ethernet port also acts as a 12W PoE (802.3af) PD (powered device) with an add-
on PoE module, POE-301. It supports both mode A and mode B PSE (power sourcing
equipment). POE-301 is not included in product package and should be ordered separately
if needed. Passive PoE is not supported.
8.1.1.4. I/O Port
The I/O port (J8) is the main interface of OBU-352 for console, in-vehicle networks and
peripherals. The I/O port connector is JST SM20B-CPTK-1A-TB, and the mating cable
connector is JST 20CPT-B-2A (see
assembly with 24AWG wire should be used to connect to vehicular wire harnesses.
