Overview

The ZJTS816 is an industrial serial device server that brings up to 16 RS-232/485 serial ports onto the Ethernet network through 2 × 10/100Base-T auto-negotiating ports, with a dedicated RS-232 Console port (RJ45, 9600bps 8-N-1) for local configuration and management. It is housed in a standard 1U, 440mm-wide rack-mount metal chassis with IP40 protection, powered by AC 220V (85–264VAC/77–300VDC wide range) with reverse-polarity and overload protection, and supports DHCP/Telnet/TCP/UDP/IP/ICMP/ARP/Modbus TCP/IP protocols with a real COM driver for Windows. An optional wide-temperature build extends operation from -40 to +75°C with strong EMC immunity for demanding industrial environments.

Is This the Right Fit?

Six real deployment scenarios matched to this model's actual datasheet specifications.

Legacy Serial Equipment to IP Networking16 × RS-232/485 ports let a single 1U unit bring an entire rack of legacy serial devices — PLCs, meters, sensors — onto the Ethernet network as a legacy serial to IP gateway.

PLC Automation Cell IntegrationBuilt-in Modbus TCP/IP protocol support (alongside DHCP/Telnet/TCP/UDP/IP/ICMP/ARP) lets the ZJTS816 bridge RS-232/485 PLC automation cells directly into a Modbus TCP/IP-based SCADA network.

Outdoor / Unconditioned Equipment RoomThe optional wide-temperature build operates from -40 to +75°C with strong EMC immunity, suited to unheated equipment rooms and outdoor cabinets exposed to seasonal extremes.

19-Inch Rack Cabinet InstallationStandard 1U height and 440mm rack width (with 466/483mm mounting-ear span) let the ZJTS816 mount directly into a 19-inch rack cabinet alongside other rack-mount networking gear, in an IP40 metal enclosure.

Console Port Local Debug & ManagementThe dedicated RS-232 Console port (RJ45 connector, 9600bps 8-N-1) gives technicians direct local access to configure and troubleshoot the unit without going over the network — useful during initial commissioning or when the Ethernet link is down.

1U High-Density 16-Port Serial AggregationA single 1U, 440mm rack-width chassis aggregates 16 RS-232/485 serial ports onto 2 × 10/100Base-T Ethernet uplinks, reducing rack space compared to deploying multiple smaller serial servers.

Not a good fit if:

Powered by a single AC 220V (85–264VAC/77–300VDC) input only — no redundant dual-power-input option is listed for this series.
IP40 enclosure only — needs a rack cabinet or additional protection for direct outdoor rain/dust exposure.
Fixed 2 × 10/100Base-T Ethernet uplinks only — no gigabit or fiber uplink option; not intended as a high-throughput backbone aggregation switch.
