Frequently asked questions

Use the battery status indicator in data collection software to confirm which battery is “in use” before hot-swapping batteries.

Located on the ALTUS CD there is a text file called “APS-3_Default_Config.txt” or “APS-3_Rev2_Default_Config.txt” Follow the Factory AsteRx2/AsteRx2e receiver Settings in section 3 of this manual to upload that file into the APS-3.

There are three key items that must be specified to get the correct GSM SIM card and service from your cellular service provider; GSM SIM card (not UMTS) Data service only No IMEI number (i.e. no associated hardware/handset)

Base stations transmit different messages types. It is important to confirm what message type(s) the base is transmitting so the Rover can be set accordingly.

In the main view of the controller, select the Start Menu, next click Settings Menu, then select the System tab, lastly select the About icon which will display the Windows Mobile® version.

The APS-3 remembers the settings set during the last configuration and uses these upon restart. To stop logging upon startup, Close the Data File and reconfigure the base/rover. Reconfigure by selecting the green check mark on GPS Base/Rover tab.

Get the latest firmware release from ALTUS. Connect the 5 pin controller serial cable (SER1) to the bottom of the APS-3, connecting the DB9 side of the cable to a PC’s RS232 serial port. Power on the APS-3 and open RxControl. Once connected to the APS-3 click the tools tab and select upgrade receiver. Click Ok to close connection. Then click “Next” in the RxControl Upgrade Wizard. Next select the COM port used for the connection between the APS-3 and computer followed by clicking “Next”. Locate the appropriate SUF file, and click “Next”. Then select “Upgrade”, and proceed with any other on screen directions. Once completed, firmware version can be verified in the “Help” tab of RxControl in the “Receiver Identification” menu. It can also be checked using SurvCE and FIELDGenius.

A setting in the APS-3 may have been incorrectly set causing a disruption in communication. Power the unit off, remove all power sources, turn the unit back on. After the unit boots, perform a hard reset and upload the default script. If you are using a USB-Serial adapter, the adapter may not be compatible with the APS-3. If possible connect directly to a physical COM port on the PC. Otherwise, adapters using prolific drivers have been found to work more reliably.

The APS-3 model is determined by the APS-3 Serial number found on the bottom of the unit. Serial numbers in the 10000 series are classified as APS-3. Serial numbers in the 20000 series are classified as APS-3 V2.

Be sure that you are selecting the APS-3 model in your data collection software. Selecting the wrong model version will cause communication issues with the GSM modem. The APS-3 V2 GSM modem requires that Flow Control be enabled on the system. If this was previously turned off it will need to be re-set. You can accomplish this by re-uploading the default script to the receiver or by sending the command SCS,COM2, , , , RTS|CTS using data collection software or RxControl.
