Specifications & version options

Choose the configuration, not just the enclosure

The reviewed catalogue covers several related serial-server families. These limits prevent features from being carried from one variant to another.

• Single-port, 2-port and 8-port configurations are available; the ordered serial-port count must be selected before quotation.
• Basic single-port families use 10M Ethernet. High-performance and multi-port families use 10/100M Ethernet.
• RS485, RS232 and RS422 are family interface choices. They are not presented as simultaneous interfaces on every unit.
• Modbus RTU/TCP gateway operation is in the reviewed scope. TCP, UDP, HTTP and MQTT are available only on the documented family variants.
• DC 8–28 V is the common low-voltage option. PoE or AC input applies only to the configurations that list it.
• BACnet, a Linux operating system, universal isolation, protection ratings and certificates are not part of the approved public facts for this family.

Typical applications

• Bridge Modbus RTU devices to Modbus TCP
• Tunnel serial data over TCP or UDP
• Separate multiple serial loops with 2- or 8-port configurations
• Use HTTP or MQTT on the family variants that document those functions
