User manual

• The device that The Shark is attached to may require a Null Modem

connector or cable between The Shark and the device. See Section 4.3.1

DTE vs. DCE.

• Make sure that The Shark’s switch 2 is in the correct position to match the

remote device communication protocol. Switch 2 in the “on” position is

for RS-232 communications and in the “off” position is for RS485

communications. See Sections 4.3 and 4.4.

4. The Bluetooth

wireless link between the Shark and my remote Bluetooth

wireless enabled device disconnects.

• A metal enclosure or an object nearby that could attenuate the RF signal

makes transmission difficult and can reduce the range significantly. In

this case, it is necessary to use an external antenna/cable assembly to bring

the signal out to get the range back to an acceptable distance. See section

6.4.4. Antennas.

• Your Shark may be too far away from the computer, PDA or equipment

you are trying to establish a Bluetooth

wireless communications link

with.

• Check to make sure the antenna connection is solid or not damaged.

5. The Shark’s blue indicator light is not flashing.

• Make sure switch 1 is in the on position. See Section 2.4 Switches.

• The internal battery power may be low. Make sure that external power is

connected to the Shark. Then the battery will be recharged.

6. The Shark’s green indicator light is not on.

•

Switch 3 may be in the optional off position. See Section 2.4 Switches.

• The Shark may be operating from the internal battery only. In this case,

the green LED will be off.

• If your intention is to operate from an external power source, make sure

that external power is connected to the Shark. If you want an indication

that you are using external power, then switch 3 will needs to be ON.

7. I cannot connect to the Shark using the Shark Config program.

• Be sure the power (switch 1) is on.

• Although external power is not needed due to the internal battery, it may

be necessary to use if the battery has been drained.

• Be sure you are using a null modem RS-232 connection between the Shark

and the computer’s COM port.

• Make sure the program’s baud rate is the same as the Shark if using the

“Connect” button, otherwise use the “Discover Baud Rate” button to

connect.

8. I cannot access the Device Discovery in the Shark Config program.

•

Accessing the Device Discovery requires The Shark to be configured as a

Master using the Shark Config program.
