2. Overview of the TCW-1450 for WCDMA

2.1. Overview of FunctionThe TCW-1450 equipment case makes drive testing with TEMS Investigation WCDMA practical. The case keeps external devices securely in place, while greatly simplifying the task of connecting them to the PC. To facilitate handling, the case is equipped with a panel where connectors are placed.

The TCW-1450 accommodates up to three WCDMA user equipments (UEs), primarily from Motorola or Nokia. It also has room for one TEMS Scanner for WCDMA, equipped with an internal GPS. A separate GPS unit can be installed if no TEMS Scanner is present.

A 7-port USB hub is used for connecting all external devices to the PC running TEMS Investigation WCDMA. The TEMS Scanner (or external GPS) is connected to the USB hub via a USB-to-RS-232 converter that is integrated with the power supply unit.

The TCW-1450 is powered with 12 V DC from the vehicle cigarette lighter outlet. Inside the case the power is distributed to the two cigarette lighter outlets on the main panel (next to the XLR-type power inlet), and to the power supply unit. This unit in turn supplies power to the USB hub, the UEs, the optional TEMS Scanner if installed, and the cooling fan. The two cigarette lighter outlets on the connector panel can be used to power supply an external GPS, or the PC (via a vehicle adapter).

A separate cigarette lighter outlet box is provided for the in-car phone chargers used to charge the UEs.

Note: USB cables, UE in-car phone chargers, and external antennas are not delivered with the TCW-1450. These items must be purchased separately.

3. Installation, Details on Components, Handling

3.1. Vehicle Installation of the TCW-1450The TCW-1450 is primarily intended for installation in a vehicle for drive testing. It can however also be used in other environments as long as 12 V DC power can be supplied.

3.1.1. Seat Mounting Kit

3.1.2. Adaptation for Right-hand Driven VehiclesThe mounting of the interior of the TCW-1450 is adapted for left-hand driven vehicles. It is easy to adapt the case to right-hand driven vehicles:

• Open the four screws located at the bottom of the case (accessed from the outside).

For best possible support during driving, use the seat mounting kit to fasten the case to the passenger seat. The case is then kept safely in place by means of a belt wrapped round the seat and attached to the case with snap-hooks.

• Lift the interior of the case, rotate it 180 degrees, and replace it into the case. Tighten the screws in the bottom.

3.2. Power SupplyPower is supplied to the TCW-1450 through a cable that should be connected to the vehicle power system. The cable comes with a universal plug so that it can be plugged into a vehicle outlet. The universal plug fits cigarette lighter outlets as well as 12 mm power outlets.

The accepted input voltage range is 10.5–16 V DC.

The center pin connector should be connected to the positive (+) pole and the outer shield to the negative (–) pole of the power source.

For safety reasons the universal plug is equipped with a car-type 8 A fuse and an LED for fuse check. Spare fuses are delivered along with the case in a plastic bag containing consumables.

The power cable connects to an XLR-type socket inside the case. The polarities are as indicated in the figure below.

Note: It is very important not to supply the TCW-1450 with a voltage exceeding 16 V. The case cannot be powered directly by a vehicle with a 24 V power system.

The total power consumption of the TCW-1450 when nothing is connected to the two cigarette lighter outlets corresponds to a current not exceeding 2 A. Making use of either or both of the cigarette lighter outlets will naturally increase the power consumption.

3.3. Power Supply UnitA power supply unit is installed in the TCW-1450. It incorporates five voltage regulators and one USB-to-RS-232 converter.

Along the right edge of the power supply unit are four connectors:

• 12V DC in is the power inlet to the power supply unit, and it is connected to the XLR type power input.

• Fan is the power outlet to the cooling fan. Do not connect anything except the fan to this outlet, as the output voltage is load dependent.

• 12V DC Out1 and 12V DC Out2 are power outlets for accessories. One is connected to the cigarette lighter outlet box, and the other to the TEMS Scanner if installed.

The outlet marked USB-Hub is a 5 V supply outlet for the 7-port USB hub.

The four outlets marked Mobile/UE are not used for the UEs and should be left unconnected.

A USB-to-RS-232 converter is integrated with the power supply unit. It is connected to the 7-port USB hub via the USB type B connector, and to the TEMS Scanner (or external GPS) via the 9-pin type D connector.

At the top of the power supply unit are found a 5 A fuse and an LED indicator which lights up when power is applied to the case. Note that the fuse only protects equipment powered by the power supply unit; it does not protect the two cigarette lighter outlets next to the XLR-type power inlet. These are only protected by the 8 A fuse in the power cable universal plug.

WARNING: If you choose to construct your own power cable to be able to connect directly to a screw terminal or other kind of power outlet, be sure to connect an 8 A fuse in series with the positive (+) lead. Otherwise the two cigarette lighter outlets next to the XLR-type connector will be unfused, which may cause a fire hazard.

LZT 108 6698 R1B 7


3.4. Cigarette Lighter Outlet BoxBelow the 7-port USB hub a box with three cigarette lighter outlets is installed. It is intended for the in-car phone chargers used to charge the UE batteries.

3.5. User Equipment (UE) HoldersThe TCW-1450 for WCDMA is equipped with three universal holders intended for the UEs. To install an UE, just press the halves of the holder apart and place the UE in the holder.

3.6. USB HubA 7-port USB hub allows the UE USB ports and the USB-to-RS-232 converter integrated with the power supply unit to be simultaneously connected to one USB port on the PC.

The USB hub is power supplied from the power supply unit.

3.7. USB-to-RS-232 Serial ConverterThe task of the USB-to-RS-232 serial converter is to convert data and transfer it between the USB hub and a TEMS Scanner or external GPS, devices which are equipped with an RS-232 port only.

In order for the PC to detect the COM port of the converter, some driver files (delivered with TEMS Investigation WCDMA) must be installed on the PC. See appendix A.

Once the serial converter is correctly installed, the PC operating system will detect one additional COM port. The port will be assigned the next available COM number; what number is used depends on what ports have already been defined, so it cannot be predicted. It is possible to inspect and to change the COM number by using the Device Manager in Windows.

8


The COM port will always be detected by the PC, whether or not any equipment is connected to it. In other words, disconnecting the device connected to the converter port does not affect port detection.

3.8. User Equipments (UEs)The UEs in the TCW-1450 have a USB-type data connection. The USB communications cable is inserted in the UE connector below the keypad, and its other end connects to the USB hub. Each in-car phone charger is connected to the UE (Nokia: charger plugs directly into the UE itself; Motorola: charger is inserted into the connector on the side of the UE’s USB cable plug) as well as to an outlet in the cigarette lighter outlet box.

To establish contact with the UEs in TEMS Investigation, you must identify them in the application. How to do this is explained in the TEMS Investigation WCDMA documentation.

3.9. Installing a TEMS ScannerThe TEMS Scanner is not installed in the TCW-1450 by default, but it can be purchased separately. You then need to install the scanner in the case prior to use.

Begin the installation by removing the two screws holding the smallest of the three mounting brackets on the connector panel to the right. Remove the blank bracket and replace it with the one delivered in the TEMS Scanner mounting kit. Turn the bracket so that the panel-mounted lens with the plastic light guide is closest to the UE holders. Fasten the bracket with the two screws.

Next, connect the two cable connectors for the scanner antenna and GPS antenna (one SMA and one SMB), mounted on the two short coaxial cables, to the mating connectors on the TEMS Scanner.

Now connect the scanner to the power supply unit using the power and communications cable. Plug the DB9 male connector into the scanner, the DB9 female connector into the RS-232 mating connector on the power supply unit, and the two-way power connector into one of the two outlets marked

Note: The TCW-1450 must be connected to the PC before TEMS Investigation is started. Otherwise TEMS Investigation will not detect the external devices.

LZT 108 6698 R1B 9


12V DC Out (which one does not matter). Insert the plastic light guide into the hole in the plastic bracket mounted on the scanner front plate. The light guide should be inserted until it stops (about 5 mm).

Finally, fasten the scanner mounting plate to the case. (To facilitate this step, it is helpful to remove the blank cover next to the XLR inlet on the connector panel.) Insert the metal tongue of the mounting plate into the slot below the fan beneath the connector panel. Press the plate against the floor of the case and lock it with the supplied screw.

To establish contact with the scanner in TEMS Investigation, you must identify it in the application. How to do this is explained in the TEMS Investigation WCDMA user manual.

3.10. Installing an External GPSIf no TEMS Scanner is mounted, an external GPS can be installed instead.

To install a Garmin 35 PC in the TCW-1450, two connections are required. Insert the cigarette lighter plug into a free cigarette lighter outlet, then connect the 9-pin type D connector to the RS-232 mating connector on the power supply unit. (This arrangement is not shown in the diagram in section 2.4, where a TEMS Scanner is installed.)

3.11. External AntennasA set of magnetic mount external antennas is delivered with the UEs and with the TEMS Scanner. The purpose of using external antennas, mounted for example on the vehicle roof or hood, is to amplify the signal strength and to uniform the reception conditions at the UEs and the TEMS Scanner.

The number of antennas needed is dependent on the configuration:

• If the case only contains UEs:

– One magnetic base with a monopole radiator for each Motorola UE.

– Two magnetic bases with monopole radiators (one for WCDMA, one for GSM) for each Nokia UE.

– One GPS unit with built-in antenna.

• If the case contains UEs and a TEMS Scanner:

– One magnetic base with monopole radiator for each Motorola UE.

10


– Two magnetic bases with monopole radiators (one for WCDMA, one for GSM) for each Nokia UE.

– One magnetic base with monopole radiator for the TEMS Scanner.

– One GPS antenna unit for the scanner’s internal GPS.

To connect a monopole antenna to the UE, take the short coaxial cable supplied with the UE and connect the angled coaxial connector to the antenna outlet at the back of the UE. Nokia UEs have two such outlets; the one on the left is for WCDMA, but the two antennas are identical. The SMA jack at the other end of the coaxial cable is plugged into an SMA–FME adapter which in turn connects to the monopole antenna.

To connect a monopole antenna to the TEMS Scanner, just screw the SMA cable connector onto the mating connector on the panel to the right. The scanner’s GPS antenna is equipped with an SMB cable connector which is snapped onto the mating connector on the panel.

3.12. Locking the TCW-1450A padlock (4-digit combination lock) is provided for locking the case.

Note: Do not keep the TCW-1450 closed during operation, or the temperature inside it will become too high.
