Overview

The ZJTS808 is an industrial 8-port desktop serial device server that connects up to 8 RS-232/485 serial devices to an Ethernet network through 2 fixed 10/100Base-T(X) LAN ports. It runs a 32-bit 100MHz processor with 2MB memory, supports DHCP, Telnet, TCP, UDP, IP, ICMP, ARP and Modbus TCP/IP, offers WEB-browser remote configuration with a bilingual Chinese/English setup menu, and carries built-in 15KV ESD surge protection on every serial port. Powered by DC5V (5–24VDC via an optional 220V-to-5V adapter) or AC220V (85–264VAC/77–300VDC) with reverse-polarity and overload protection, it operates from -10 to +60°C (wide-temp version -40 to +75°C) in a compact 30×106×190mm IP40 metal enclosure for desktop or wall-mount installation.

Is This the Right Fit?

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

Legacy Serial Device IP NetworkingUp to 8 RS-232/485 serial ports are freely combinable (S-232 all-RS232, S-485 all-RS485, or M 2-in-1 per port), turning eight legacy serial instruments into IP-reachable devices through the 2 × 10/100Base-T(X) Ethernet ports.

PLC & Automation Cell IntegrationModbus TCP/IP is supported alongside DHCP/Telnet/TCP/UDP/IP/ICMP/ARP, letting the 8 serial ports bridge multiple PLCs or automation controllers onto the plant Ethernet without rewiring existing RS-232/485 cabling.

Extended-Temperature Cabinet DeploymentAn optional wide-temperature variant extends the operating range from the standard -10~60°C to -40~75°C, for unheated cabinets exposed to cold winters or hot summers.

Standard Dual-LAN Port — No Selection NeededEvery ZJTS808 unit ships with 2 × 10/100Base-T(X) Ethernet ports built in as standard — unlike models where port count is an option, there is no single-LAN version to choose from.

Desktop High-Density Multi-Device Access8 RS-232/485 ports in a compact 30×106×190mm desktop metal enclosure let one unit aggregate more serial devices than the smaller desktop models in this series, without needing rack or DIN-rail installation.

Built-In 15KV ESD Surge Protection on Every PortAll 8 serial ports carry built-in 15KV ESD surge protection plus overall reverse-polarity and overload power protection, adding resilience against electrical transients along long industrial wiring runs.

Not a good fit if:

Single power input only (DC5V or AC220V) — not a dual-redundant power design; add external backup power if input redundancy is required.
IP40 metal enclosure only — not rated for direct outdoor rain/dust exposure without an additional cabinet.
A serial-to-Ethernet device server, not a network switch — the 2 LAN ports connect the unit itself to the network and do not provide VLAN/RSTP or multi-device switching.
