The Bluetooth®Module RS-232 IP67 is a serial Bluetooth®adapter. As wireless
serial adapter (WSA), the module is used, e.g., as cable substitute for serial
connections, while permitting easy access both via tablet PCs or smartphones, as
well as via standard PCs with Bluetooth®interface.
The WSA is equipped with a serial interface for data exchange according to the
RS-232 standard. It also features an internal antenna for wireless data exchange
according to the Bluetooth®Serial Port Profile (SPP) standard.
The WSA meets IP 67 environmental protection ratings. The 5 m long connecting
cable provides both data and power supply for the device, while meeting IPX0
environmental ratings. The device may be installed at any location within the
range of the connecting cable that is in line with the requirements for the specific
application.
The current operating and connection status is indicated (visualized) by 5 LEDs.

3.3.2 Antenna
The WSA has an integrated antenna with low directivity. The antenna is located
near the company logo. If there is line of sight between two communicating
devices, the WSA must be aligned such that the company logo is facing the front
of the other device (see figure “Alignment of the WSA”).
Figure 6: Alignment of the WSA
The antenna diagram below illustrates antenna wave deflection on rotation around
the longitudinal axis of the WSA. The deflection characteristics of the antenna can
change, depending on what type of surface the WSA is installed.
