HAC-Smart Series is a product which is based on the standard wireless module. It adds a serial port convertor and a black aluminum extruded shell. It provides standard serial interface, state indicator, selection and setting of parameter. It can embed many kinds of standard wireless modules which are made by us. You can see the technical specification such as frequency, power, sensitvity, voitage, current, distance in our wireless product specification.
* The control board of M1 RF Module can provide standard TTL, RS232 or RS485 data port.
* Data interface: The M1 has a positive end and a negative end of DB9.
* You can put many wireless modules in it, for example HAC-UP Series, HAC-UM Series, HAC-UN Series, HAC-LM Series, HAC-LN Series, HAC-UEM Series, HAC-UEN Series, HAC-US Series.
* The shell of wireless connecter is made of aluminum.
* Dimension: 78mm×45mm×19mm (not including the joint)
* Antenna: The standard SMA which is lengthened, 50Ω impedance (the shorter SMA is avfailable if need)
* Configuration: A 10cm helical SMA antenna which has an elbow-joint.
* It has indicator light which can indicate the state of power and transmitting data.
* You can choose the channel frequency or parity bit by using switch, but this is only for the HAC-UP Series, HAC-UM Series, HAC-UN Series, HAC-LM Series and HAC-LN Series.
* To enable the setting function by using switch, you can set the corresponding parameter of module through the serial port.
