The EKI-1521, EKI-1522, and EKI-1524 feature two independent Ethernet ports and MAC addresses to provide a redundant network mechanism that guarantees Ethernet network
reliability. These serial device servers are designed to connect RS-232/422/485 serial devices such as PLC, meters, sensors, and barcode readers to an IP-based Ethernet LAN.
They allow nearly any device with serial ports to connect and share an Ethernet network, while also providing various operations such as COM port redirection (Virtual COMport),
TCP server, TCP client, and UDP mode. With COM port redirection mode, standard serial operation calls are transparently redirected to the servers, guaranteeing compatibility with
legacy serial devices and enabling backward-compatibility with existing software. With TCP server, TCP client, and UDP modes, the EKI- 1521, EKI-1522, and EKI-1524 ensure
compatibility in network software using a standard network API. Moreover, serial devices can be made communicate with other devices via peer-to-peer, thus eliminating the need
for an intermediate host PC and software programming More information: Technical details | Serial ports quantity | 2 |  | Serial interface type | RS-232/422/485 | | Ethernet LAN data rates | 10,100 Mbit/s | | Networking standards | IEEE 802.3, IEEE 802.3ab, IEEE 802.3u | | Baud rate | 921.6 Kbit/s | | RS-232 signals | CTS, DCD, DSR, DTR, GND, RI, RTS, RXD, TXD | | RS-422 signals | GND, RxD+, RxD-, TxD+, TxD- | | RS-485 signals | Data+, Data-, GND | | Data bits | 5, 6, 7, 8 | | Parity bit | Even, Mark, Odd, Space | | Stop bits | 1, 1.5, 2 | Design | International Protection (IP) code | IP30 | Power | Power source type | DC | | Power consumption (typical) | 3.2 W | | Input voltage | 12 - 48 V | Indication | LED indicators | Yes | Sustainability | Sustainability compliance | Yes | | Sustainability certificates | CE, Federal Communications Commission (FCC) | Weight & dimensions | Width | 30 mm | | Depth | 140 mm | | Height | 95 mm | | Weight | 432 g | Operational conditions | Operating temperature (T-T) | -10 - 60 °C | | Storage temperature (T-T) | -20 - 80 °C | | Operating relative humidity (H-H) | 10 - 95 % |
