Bluetooth Wireless Serial Port Adapter Support[NEW]
(P/N HDWBTRS232N)

Generally the wireless serial adapters are sold in pairs. Before the devices can be used they must be paired. Pairing creates a virtual link between two unique wireless serial adapters.

 

Manual This is the manual for the Wireless Serial Adapter.
Terminal Program Use this terminal program to manually configure the Wireless Serial Adapter.
Cable Replacement Setup (manual setup) Procedure to configure  units as a cable replacement.
Multi-adapter setup (manual setup) The following instruction shows how to setup a master adapter to connect to multiple slaves. (e.g, an adapter on a computer and a slave on eace CNC machine).
   
   
   
   


Questions & Answers

  1. No communication is occurs between my device and computer.

  1. If you use a straight through cable to connect your computer to the remote device then the switch on the HDWBTRS232N connected to the PC must be toward the connector. The HDWBTRS232N connected to the remote device must be towards the antenna.

  2. If you use a null modem cable to connect your computer to the remote device then the switch on the HDWBTRS232N connected to the PC must be toward the connector. The HDWBTRS232N connected to the remote device must be towards the connector.

  3. Disable flow control on both Bluetooth Wireless Serial Adapters.

  4. Loopback RTS to CTS (Pin 7 to Pin 8) on the remote connector if possible.

  5. The device may need a DSR/DTR signal. Click here for a solution.

  1. How should the wireless adapter be configured for a device that requires a line configuration other than no parity, 8 databits, one stopbit.

Always set the adapter to 8 databits, no parity, one stopbit. The device is simply a conduit of bits.

  1. How do I pair the wireless adapter with a Bluetooth computer or Bluetooth dongle?

To learn how to pair the Bluetooth wireless serial adapter with another Bluetooth device <click here>.

  1. How is DTR/DSR signals (pins 4 & 6) handled by the Bluetooth Wireless Adapter?

The DTR signal is rarely used or if used necessary in serial communication applications. For maximum compatibility, the wireless serial adapter (HDWBTRS232) simply loopback the DTR to DSR (Pin4 to Pin6). By doing this, if the device asserts DTR indicating it will read an asserting DSR. For devices that require an asserting DSR but is not asserting DTR the DSR signal (Pin6) can be shorted to RTS(Pin7).

  1. How do I configure for Even Parity, 7 Data Bits, One Stop Bit (E71)?

Set Line Characteristic for Device/Computer Connected to Wireless Adapter1 : 9600,7,e,1
Set Line Characteristics for Wireless Adapter1 to: 9600, 8,n,1
Set Line Characteristics for Wireless Adapter2 to: 9600, 8,n,1
Set Line Characteristic for Device/Computer Connected to Wireless Adapter2 : 9600,7,e,1


This will work in most of the cases because Bluetooth adapter only cares of number of bits and not of meaning of those.
