Diferences between RS232 and RS485
Transmission method: RS232 wireless router adopts unbalanced transmission that is also called single-ended communication. RS485 use a balanced transmission, that is, differential transmission.
Transmission distance: RS232 router suits for local devices communication, the transmission distance is generally not more than 20m. RS485 transmission distance can reach tens of meters to kilometers.
RS-232 allows only one-to-one communication, while the RS-485 interface allows up to 128 transceivers on the bus
RS232 is defined as a single-ended standard for increasing the communication distance in low-speed serial communications. RS232 take unbalanced transmission that is the so-called single-ended communication. The received and originating data signal is relative to the signal ground.
RS-485 and RS-232 are not the same. Its data signal uses differential transmission, also known as balanced transmission.

What is an industrial GSM router?
With the increasing use of GSM wifi router in the field of data transmission, ADR has developed a GSM Modem based on the need for a simple and practical GSM communication solution.
The gsm wireless router is specially designed for the complex environment of the industrial site and conforms to EMC test specification. As a terminal product, it has built-in wireless communication module, which can be set by using the AT command on the PC via RS232 (optional RS485 or TTL level) interface. This makes it a common GSM dual-frequency terminal product in voice and data communications.
At the same time, you can quickly apply it to product development, and it can also be used as an integral part of the product. After E-lins's years of a field test in actual combat, it is reliable wireless data transmission terminal partner in telecommunications, site monitoring, and many other areas of wireless communications, which will bring great convenience to your work.
