SV652 : 500mW Industrial Grade Aluminum Housing Long Range RF Modem With ESD Protection

SV652 is an Industrial class & highly-integrated RF modem. TTL / 232 /485 can be chosen corresponding to SV652-TTL / SV652-232 / SV652-485. SV652 has good sensitivity and 500mW output power to achieve long RF range and reliable RF communication. To avoid the interference, SV652 provides 40 frequency channels and configurable Net ID. SV652 is flexible but easy to use, it comes with many parameters, such as: frequency, data rate, output power, Net ID, Node ID. Users can configure the parameters through PC or customer’s own device.
SV652 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.

Typical Application Circuit of RF Modem SV652

Pins of RF Modem SV652

Pin No.	Definition	Description
1	VCC	Connected to the positive power supply (typical 5V)
2	GND	Connected to ground
3	TXD	TXD of the module and connect to external RXD
4	RXD	RXD of the module and connect to external TXD
5	SET	Configuration mode enable (low to enter into the setting mode, leave open or connect high level to exit setting mode) Valid when CS Pin is high or leave open.
6	CS/NC	For the default version of the module, this pin needs to be left floating (the module has a built-in anti-crash self-reset circuit) Note: Customers can customize the sleep version of the program (without self-reset function), low level sleep, current lower than 5uA, default high level output.
