PLANET 1-Port RS232/RS422/RS485 Serial-Ethernet 1 x SFP

The PLANET ICS-2105AT is an industrial-grade serial device server that bridges RS232/422/485 serial communications to 100BASE-FX fiber Ethernet networks. Designed for system integrators and industrial applications, it features a DB9 port for RS232 and a terminal block supporting 2-wire RS485 and 4-wire RS422/RS485 standards, with data rates up to 921,600 bps. The device offers multiple operation modes including VCOM, RFC2217, TCP Server/Client, UDP, and Modbus converter server/client. Its fiber-optic connectivity extends network distances reliably in harsh environments, operating in temperatures from -40°C to 75°C. The ICS-2105AT supports IPv4/IPv6 dual stack management, remote configuration via web or Telnet, and includes security features like IP access control and event notification through Syslog, SNMP trap, and relay output alarm. A cost-effective solution for modernizing legacy serial devices without replacing existing infrastructure.
