IDS-5042-I+ is an innovative secure 4-port RS-422/485 to 2 ports LAN secure device server with isolation featuring the standard features of device server, such like TCP/IP interface and versatile operation modes: Virtual Com, Serial Tunnel, TCP Server, TCP Client, UDP. In addition, the Windows utility, DSTool, could configure multiple devices and set up the mappings of Virtual Com. The features of NAT Router Pass-Through, DDNS, and PPPoE make it more convenient for administrators to configure ORing’s device servers through NAT router from different IP domains or Internet via modem remotely. On the other hand, IDS-5042-I+ can simultaneously transfer data up to 5 redundant host PCs to aovid Ethernet connection breakdown or any host PC fails. Further, IDS-5042-I+ features HTTPS, SSH, and SSL encryption to assure the security of critical data transmission.

IDS-5042-I+ supports RS-422/485 and provides dual redundant power inputs, 12~48 VDC, on terminal block to guarantee a non-stop operation. RS-422/485 serial ports are with 2KV isolation. Further, IDS-5042-I+ features PoE P.D. (Power Device) function, compliant with IEEE802.3af standard, with 1kv isolation on the PoE port. With wide operating temperature, -10~70°C, and rugged IP-30 housing design, IDS-5042-I+ could operate in the harsh industrial environment. Therefore, IDS-5042-I+ is the best solution to the high demand of secure serial to Ethernet critical data communication.
