Overview
The ZJTS832 is an industrial serial device server that supports up to 32 RS-232/485 serial ports alongside 2 × 10/100Base-T RJ45 Ethernet ports and a dedicated RS-232 Console port (9600bps, 8,N,1) for local setup. Housed in a 1U IP40 metal enclosure (44×212×440 mm) for standard rack mounting, it is powered by AC220V (85–264VAC/77–300VDC) with reverse-polarity and overload protection, drawing a maximum of 4 W, and supports DHCP/Telnet/TCP/UDP/ICMP/ARP/Modbus TCP/IP with a real COM driver for Windows NT/2000/XP/Vista/7/10/11. Every serial port carries built-in 15KV ESD surge protection, an optional wide-temperature version operates from -40 to +75°C, and the unit is backed by a 5-year warranty.
Is This the Right Fit?
Six real deployment scenarios matched to this model's actual datasheet specifications.
Legacy Serial Fleet IP NetworkingUp to 32 flexibly combinable RS-232/485 serial ports let an entire fleet of legacy serial equipment go online over the 2 × 10/100Base-T Ethernet ports at once — a core legacy serial to IP use case.
PLC Automation Cell IntegrationBuilt-in Modbus TCP/IP protocol support (alongside DHCP/Telnet/TCP/UDP/ICMP/ARP) lets PLCs and automation controllers on the serial side reach an Ethernet-based SCADA/MES network directly.
Outdoor / Unheated Equipment RoomThe optional wide-temperature version operates from -40 to +75°C, matching unheated substation rooms or outdoor cabinets exposed to seasonal extremes.
32-Port Ultra-High-Density ConsolidationA single 1U (44×212×440 mm) chassis carries 32 RS-232/485 ports — the highest port count in this series — replacing several smaller 4/8-port serial servers and freeing rack space.
Large Substation / Factory Full-Site Serial Networking32 terminal-block RS-232/485 ports let one unit take in an entire substation or workshop's field serial devices (protection relays, meters, PLCs) in a single connection round instead of deploying multiple smaller boxes.
Field Wiring in Surge-Prone Switchgear YardsBuilt-in 15KV ESD surge protection on every serial port, plus AC220V input rated 85–264VAC/77–300VDC with reverse-polarity & overload protection, suits field wiring runs near switchgear and power equipment.
Not a good fit if:
- Single AC220V power input only — no redundant dual-power option; sites needing power-loss redundancy should plan an external UPS.
- Default 1U 19-inch rack-mount chassis — not a DIN-rail/wall-mount unit for small cabinets.
- IP40 metal enclosure only — direct outdoor rain/dust exposure needs additional cabinet protection.

Custom & OEM →32-Port Serial Device Server FAQ — ZJTS832
How many serial lines can one ZJTS832 replace?
One unit supports up to 32 RS-232/485 serial ports on terminal-block interfaces, plus 2 × 10/100Base-T RJ45 Ethernet ports — the highest density in the ZJTS family. That consolidates a whole floor of meters, controllers or legacy field devices into a single 1U chassis.
How is the ZJTS832 installed and how much space does it take?
It rack-mounts by default in a 1U IP40 metal enclosure of 44×212×440 mm, fitting any standard 19-inch cabinet. Despite 32 active serial channels it draws a maximum of 4 W from its AC220V input (85–264VAC / 77–300VDC wide range), with reverse-polarity and overload protection.
Can I manage it without network access?
Yes — a dedicated RS-232 Console port (RJ45, 9600 bps, 8,N,1) gives local setup even before the network exists. Once online, it supports DHCP, Telnet, TCP, UDP, ICMP, ARP and Modbus TCP/IP, and the real COM driver for Windows NT/2000/XP/Vista/7/10/11 maps all 32 ports into your software.
What serial parameters do the 32 ports support?
Each RS-232/485 port runs 300 bps to 230.4 Kbps with data bits 5–8, parity None/Even/Odd/Space/Mark, 1 or 2 stop bits, and RTS/CTS or XON/XOFF flow control. RS-232 wiring is TxD/RxD/GND; 2-wire RS-485 is Data+/Data-/GND. Every port carries built-in 15KV ESD surge protection.
How reliable is it for 24/7 operation?
MTBF is rated at 320,000 hours, backed by a 5-year warranty. It passes EN61000-4-2/3/4/5/6/8 EMC tests at Level 3 and IEC60068 shock, free-fall and vibration standards. Standard operating range is -10 to +60°C, with a wide-temperature option covering -40 to +75°C.
