Description
The ATOP SW5502C is a compact Wi-Fi serial device server that connects two RS-232/422/485 devices to a network over 2.4 GHz IEEE 802.11n Wi-Fi or a 10/100BASE-T(X) RJ45 port. A WPS button makes pairing with an access point quick.
It runs in VirtualCOM, TCP client, TCP server and UDP modes, so existing serial software can reach remote devices as if they were on a local COM port. It takes 9-48 VDC, mounts on DIN rail and operates from -10°C to +60°C. For Modbus RTU to Modbus TCP conversion over Wi-Fi choose the MW5502C; for dual-band 2.4/5 GHz Wi-Fi and a Gigabit port choose the SW5502.

Specifications taken from the manufacturer datasheet.
Which version do I need?
ATOP documents the SW5501C and SW5502C in one SW5501/2C row (1 or 2 serial ports). The brochure lists two 2-port versions, SW5502C and SW5502C-TB, covering DB9 and terminal-block connectors, both with a WPS button; confirm the connector type when ordering. Compared with the SW5502, the SW5502C is 2.4 GHz only instead of 2.4/5 GHz, has 10/100BASE-T(X) instead of Gigabit Ethernet and has no isolation option, with the same -10°C to +60°C rating. The MW5502C has the same listed interfaces but runs as a Modbus gateway.
Typical applications for the SW5502C
- Wireless connection of two serial devices in one panel
- Compact machines where size is the deciding factor
- Legacy PC software reaching serial devices through VirtualCOM
- Indoor production lines and plant rooms within -10°C to +60°C
- Retrofit wireless access to serial equipment without new cabling

SW5502C — frequently asked questions
What is the difference between the SW5502C and the SW5502?
The SW5502C is 2.4 GHz only, has a 10/100BASE-T(X) RJ45 port and no isolation option. The SW5502 adds 5 GHz, a 10/100/1000BASE-T(X) Gigabit port and an optional 3 kV isolated version. Both have two serial ports, take 9-48 VDC and are rated -10°C to +60°C.
What is the difference between the SW5502C and the SW5501C?
Serial port count: two RS-232/422/485 ports on the SW5502C, one on the SW5501C. Wi-Fi, Ethernet, power, housing and temperature ratings are the same.
Is the SW5502C a Modbus gateway?
No. ATOP lists it as a serial device server (VirtualCOM, TCP client/server, UDP, Reverse Telnet). For Modbus TCP to RTU/ASCII conversion on the same 2-port Wi-Fi platform, ATOP's model is the MW5502C.
What temperature range is it rated for?
-10°C to +60°C operating and -40°C to +85°C storage, in an IP30 DIN-rail housing.
How many network connections does it support?
Up to 2 TCP client connections and up to 4 TCP server connections, 4 UDP ranges, plus VirtualCOM and Reverse Telnet.
What power supply does it need?
9-48 VDC. ATOP does not list PoE input or power redundancy for this model.
