V-chip FCC 915 MHz CC1110 UART Serial passthrough Uhf Transceiver Module

 

The VT-DTMSX5-915M module is designed as a wireless sub module for wireless communication between devices like controls, POS systems, data collectors etc. It offers several addressing modes and relieves the host systems of wireless-specific task such as checksum calculation, address resolution.

It can be deployed whenever the wireless exchange of data packet between two or more parties is required.

Thanks to its small size and the external SMA antenna connector, the module can easily be installed in existing systems without any external circuits.

Note:

1. Noted that higher radio data rate causes of shorter communication disdance.

2. Noted that higher radio data rate causes of lower sensitivity.

3. Noted that lower input voltage causes of lower output power.

4. Noted that the operate temperature out of range -40℃~85℃ will influence the              center frequency.

5. Be sure to use a match antenna and mount it in the right way.

6.The environment will influence the communication disdance much.

Troubles and Processing Methods

Troubles

Processing Methods

Short distance

1. Check the input voltage; ensure it is not lower than 4.5VDC.

2. Configure the output power parameter to the max.

3. Check the antenna; ensure it is not to be shielded.

4. Configure the radio data rate to a lower value.

Communicating failed

1. Check the input voltage.

2. Reconnect the module to the host.

3. Addresses of the communicating modules are all right.

High error rate

1. Antenna does not match to the module.

2. Co-Channel interference, try another channel.

FAQ

Description

Reason and Solution

Can’t communication

1.The power supply connect not well, check the module VCC whether it is out of maximum rating.

2.The signal line connect not well, check the module SPI interface.

3.The settings of the transmitter module and receiver module are not the same. Check these modules’ register configuration.

4.Signal block. If the transmitter work with a high TX power, and the receiver was put at a short distance(<0.5m), maybe there is a signal block to make no communication.

Communication distance is too short

1.The application environment is too bad or the antenna is shield. Put the antenna to a better place outside or higher throw a coaxial line , replace it with a higher gain antenna.

2.The work space contains a same frequency interference source, or a strong magnetic field interference, power source disturbance. Try to change the carrier frequency or get far away from the source of the disturbance.

3.The power supply is not strong. Check the voltage and the current whether it is enough.

High data error

1.The power supply ripple is too big, Change the power supply.

2.Check the module register configuration, it is recommended to set as the CC1120-datasheet.

3.There is a carrier frequency interference, change the channel.

4.The antenna unmatched to the module RF interface, change another matched antenna.
