1.0 OVERVIEW The TL-3.0 Telemetry Transmitter is designed for use with strain gauge load cell devices. It communicates wirelessly to the DLM TW-3.0 Telemetry Handheld and any other product within the d+ range. The TL-3.0 operates on a free band 2.4GHz frequency and utilises a bespoke frequency hopping protocol which hops frequency 20 times per second to help reduce interference. The TL-3.0 is “paired” with a receiving device and can be viewed simultaneously on as many receiving devices as required.
1.1 NETWORK SETTING EXAMPLES Example 1: Using two TW-3.0 Handheld devices with two TL-3.0 Telemetry Transmitters within range of each other. Pair 1 needs to be paired on a network, i.e. Network 1 Pair 2 needs to be paired on a different network, i.e. Network 2 Example 2: Using two TW-3.0 Handheld devices with two TL-3.0 Telemetry Transmitters outside of the range of each other. Both pairs can be paired on the same network as they are far enough apart that interference will not occur.
Example 3: Using one TW-3.0 Handheld device with two TL-3.0 Telemetry Transmitters. The TW-3.0 is set to operate on network 1 and both TL-3.0 Telemetry Transmitters are paired, as channel 1 and channel 2 to the TW-3.0. Example 4: Using two or more TW-3.0 Handheld devices with one TL-3.0 Telemetry Transmitter. One TW-3.0 is set to Master on network 1, the second TW-3.0 is set to a Slave on network 1 and the TL-3.0 is paired on channel 1.
2.0 CONNECTIONS 2.1 LOAD CELL CONNECTION The load cell can be wired as either a 4-wire or 6-wire strain bridge. 1) 6-wire connection – Connect as the picture above. Connections to A and B are not made. Shield is optional. 2) 4-wire connection – Use Signal + and signal -, Sense + and Sense -. Make a link between Excitation + and A, and Excitation - and B. Shield is optional. 2.2 LED CONNECTION Connect the LED anode to LED+ and the LED cathode to LED – The LED should be 2VDC with an internal resistor.
2.3 SWITCH CONNECTION The operation is designed for a push button momentary switch. 2.4 ANTENNA CONNECTION The antenna connection is a U.Fl receptacle and is designed for use with the Molex 47950-0011 antenna and no other antenna may be used 2.5 BATTERY CONNECTION The battery is connected to the TL-3.0 via the 2pin JST connector on a 2.54mm pitch. The part numbers for connectors are: Part Connector Inserts 2.
3.0 OPERATION An example of how the TL-3.0 can be housed is shown below with a description of operation. Power On: To power the TL-3.0 on for use follow the steps below: 1. Press and hold the PAIR button until the LED becomes solid 2. The LED will flash once every 3 seconds if the TL-3.0 is connected to a receiving device such as the TW-3.0 Handheld Display. 3. The LED will flash once per second if the TL-3.0 is not connected to a receiving device Power Off: To power the TL-3.
Low Power Mode: When the TL-3.0 is powered but not connected to a receiving device, it will enter a low power mode which will look for signal once every 30 seconds. This is to conserve battery life when the receiving device is powered off, but it is not possible to reach the TL-3.0 to power it off. 3.1 PAIRING The TL-3.0 needs to be paired with a receiving device, in order to establish communication with a new device such as the TW-3.0 Handheld follow the steps below: 1.
3.2 CHARGING If the TL-3.0 is being powered by a battery pack then a suitable 5VDC power source can be connected to the charging connection described in section 2.6. The power source can be supplied from any PC/laptop or any mains to USB charger plug of suitable quality that provides a 5VDC output and 500mA current. WARNING! DO NOT CHARGE BELOW 0°C It is the responsibility of the OEM to ensure the battery being used is suitable for the application and to determine if it can be charged.
3.3 BATTERIES The TL-3.0 allows connection of a multiple battery types which are connected as described in section 2.5.
