Product Description
Y202-W is a two-port DTU for cabinets that need serial access over Wi-Fi, while still keeping an RJ45 Ethernet option for setup or wired networking. It is useful when two field devices need to be brought online together, especially in retrofit sites where pulling new network cable is awkward.

Before Ordering
Choose 2 RS232, 2 RS485, or 1 RS232 + 1 RS485 according to the field devices. For a single serial device, Y201-W is smaller and simpler; for four ports, use Y204-R if wired Ethernet is acceptable.
