1 IntroductionThis manual describes the contents, installation, and functionality of the
TC-1520C equipment case.Please note that instructions on how to install and operate scanners, audioquality modules, and phones are not found here. Such instructions areinstead found in the documentation accompanying these optional productkits, which are purchased separately.
2 Overview of the TC-1520C
2.1 Overview of Function
The TC-1520C equipment case makes drive testing with TEMSInvestigation practical. The case keeps external devices securely in place,while greatly simplifying the task of connecting them to the PC.
The TC-1520C accommodates up to four mobile phones as well as multiplecombinations of scanners and audio quality measurement (AQM) modules.
The TC-1520C is powered with 12 V DC from the vehicle cigarette lighteroutlet. The TC-1520C input power connector is internally bridged to oneauxiliary power cigarette lighter receptacle on the main panel (next to theXLR-type power inlet). This auxiliary power receptacle can be used withany device that accepts an automotive 12 V DC system.
Internally, the uninterrupted power supply unit (UPS) provides power to alldevices installed in the TC-1520C. The UPS has a built-in battery that canprovide temporary power to all devices when the main input power isremoved. However, this time is limited and is dependent on the number ofdevices connected to the TC-1520C case. The UPS does not providepower to the auxiliary power receptacle mentioned above.
The internal power distribution module provides five 3-pin connectors fordistributing power to the internal scanners and AQM devices, four 6-pinpower connections for providing power to the phone devices, and one USB-to-RS-232 interface.
A 7-port USB hub is used for connecting all internal and external devices to
the PC running TEMS Investigation. Devices requiring an RS-232 interfaceare connected to the USB hub through the USB-to-RS-232 converterintegrated into the power distribution board.
Note: No phone or scanner device accessories are delivered with theTC-1520C. All of these items must be purchased separately.

Internal device power panel
4.6 Phone Power Panel
Some phones require more charging power than the USB hub can provide.The 6-pin connectors marked MOBILE/EU will be used to provide thisextra power to the phones. These connectors in turn are powered via theUPS.
4.7 USB to RS-232 Port
The task of the USB-to-RS-232 serial converter is to convert data andtransfer it between the USB hub and a scanner or an external GPS deviceequipped with an RS-232 port.
In order for the PC to detect the COM port of the converter, some driverfiles (delivered with TEMS Investigation) must be installed on the PC. Seesection 2.4.
Once the serial converter is correctly installed, the PC operating system willdetect one additional COM port. The port will be assigned the nextavailable COM number; what number is used depends on what ports havealready been defined and so cannot be predicted. It is possible to inspectand to change the COM number using the Windows Device Manager.
The COM port will always be detected by the PC, whether or not anyequipment is connected to it. In other words, disconnecting the deviceconnected to the converter port does not affect port detection.

Appendix A. Current Draw Estimates forInternal DevicesThe UPS can provide a maximum of 7.5 A of current. 2.0 A is reserved forthe USB hub and any attached devices that require USB power. Thisleaves 5.5 A available for optional internal devices. The table below lists thecurrent draw of each type of internal device; from this data you canestimate the total required amperage by adding up the current draws of alldevices you plan to install.
Supported Devices Approximate Current Draw at 12 V
PCTel SeeGull LX scanner Max. 2.5 A
PCTel SeeGull EX scanner Max. 1.5 A
PCTel SeeGull EX Mini scanner Max. 1.0 A
DRT 4301 scanner Max. 1.4 A
SRU Max. 0.7 A
TEMS AQM module Max. 0.5 A
Example: If you install two PCTel SeeGull EX scanners they will draw atotal of 1.5 + 1.5 = 3 A, and you then have 2.5 A left for installing furtherdevices.
Appendix B. Procedure for Dischargingthe UPS Battery1. Do notconnect the TC-1520C power cable.
2. Power on the TC-1520C. The UPS unit will consume power over time.When the battery is completely drained, the green LED on top of thepower distribution module will go out. It will take approximately14 hours for a fully charged battery to drain.
