User manual

This setup shows the end equipment setup to the same baud rate, which would be the case

if the equipment were directly connected (with a cable). However, the above setup would

not work since the wireless devices connected to them are set to different baud rates.

4.6 Flow Control

As with baud rate, Flow Control (also called hardware handshaking) needs to be set the

same between The Shark and the equipment it is connected to. Please check your

equipment’s documentation to discover if flow control needs to be enabled or not. Then

use the Shark Config software to set The Shark the same as the equipment.

4.7 The Shark Range and Antenna Selection

The range of The Shark is dependent on the type of antenna used. The short stub antenna

that is included in the purchase of your Shark is capable of full-range Class 1 Bluetooth

wireless technology operation. Since it is a Class 1 Bluetooth

radio technology, it is

guaranteed to have 100 meters of range when communicating with another Class 1

Bluetooth

wireless enabled device. See appendix section 5.5 for a detailed definition of

the different power classes under the term “Radio Class”.

Replacement of the accompanying stub antenna included in The Shark package may be

necessary to optimize your particular application. For example, if The Shark is installed

onto an RS-232 or RS485 port that is inside a metal enclosure, then an antenna/cable

assembly will need to be used in order for robust communications to take place. Simply

unscrew the stub antenna to reveal the female SMA RF connector. This standard RF

connector can be used to attach the recommended antenna/cable assembly (see section

5.4.1) if needed.

While Bluetooth

wireless technology does not require a line-of-sight connection, the

maximum communication range will be possible when both radios have a line-of-sight

connection and are both Class 1 radios. Many factors can affect the range of

communication as estimated in this table:
