Serial WiFi Adapter - RS232

  • Model: WA232E


Sold Out


This product has been discontinued and replaced by this product: Serial WiFi Adapter - RS232 - 4th generation.

This serial WiFi adapter is similar to our UCW232C serial WiFi adapter except that this adapter has more adjustable parameters and more advanced functions.

As our other serial WiFi adapters this adapter can be used for connecting almost any standard RS232 serial device to your computer over a wireless access point or network. It will work with most RS232 serial devices and is an ideal solution for many applications including factory automation, office, laboratory, warehouse and most other commercial and consumer applications and environments.
It can be used in pairs in a point to point setup as a direct cable replacement, standard ad-hoc and infrastructure networks; you can even use it to access your serial device over the Internet through a wireless router.

The adapter's parameters can be configured using a web-browser or a software utility. The software utility works with Windows but the adapter itself (not the VCOM software) is transparent to the operating system so once the parameters are configured as desired the adapter works with Windows, Mac, Linux, Android, iOS and most other WiFi enabled devices and applications (without VCOM software). Notice that the virtual COM port software included with the software utility only works with Windows.

The free downloadable software utility includes the virtual COM port software which creates a virtual COM port in Windows. The virtual COM port can then be used almost as if it was a regular native serial COM port.
This adapter also works with several versions of 3rd party VCOM software (only tested with Windows).

This Serial to WiFi adapter is designed around the ARM Cortex M3 166Mhz processor, which ensures reliable operation, all basic functions and multiple advanced functions such email/auto warning functions, Modbus (RS485 version only) and time settings/NTP server.

A USB cable is included for powering the adapter but a standard mini USB 110VAC/5VDC power supply adapter can also be used. Alternatively this serial to WiFi adapter can be powered by 5 - 27VDC through the screw terminals on the side of the adapter or by pin 9 in the DB9 connector.
