Printing this Readme File Introduction and New Firmware List ---------------------------------- The Trimble Utilities Installation updates all necessary Trimble GPS Total Station 4700/4800 software. This installation comprises a GPS Receiver upgrade and a Communications Processor upgrade for both the 4700 and 4800. The following list details the upgrades contained in this installation package: o 4700 GPS Receiver Version 1.20 (replaces Version 1.13) o 4700 Communications Processor Version 1.42 (replaces Version 1.31) o 4800 GPS Receiver Version 1.20 (replaces Version 1.13) o 4800 Communications Processor Version 1.42 (replaces Version 1.29) WinFLASH : Trimble Software Upgrade Application Version 1.05 ------------------------------------------------------------ WinFLASH is a Windows 95/NT PC application which is used to upgrade the software in the Trimble GPS Total Station 4700/4800, and the Trimble System Controller TSC1. Full instructions are given while running WinFLASH, and context sensitive help is available by pressing the [Help] button on the WinFLASH screen. For instructions on connecting a Trimble 4700/4800 to a PC, see "Cable Connections" below, or from the Help Contents select the topic "Configuring the 4700/4800 receiver". WinFLASH Software update: o From the "Operation Selection" dialog box it is now possible to check the versions prior to upgrading by selecting "Retrieve software versions" from the menu. The same operation may be selected after upgrading to confirm that the upgrade was successful. Note: For the 4800 receiver, following a Communications Processor upgrade (on 4800 port 3), it is necessary to reconnect the cable to 4800 port 2 (as described in "Cable connections" in the Section "4800 GPS Receiver Version 1.20") and power down/up prior to selecting "Retrieve software versions". The software upgrades installed by WinFLASH are listed in the following sections. Both a GPS Receiver version and Communications Processor version must be installed together, which require separate operations from within WinFLASH. Commset Version 1.18 (PC software which is automatically installed) -------------------- Commset is a Communications Processor Utility used to install Communications software. It is integrated into WinFLASH, and invoked automatically. It can also be used to change the internal radio frequency by selecting from the Start-Programs-WinFLASH menu. 4700 GPS Receiver Version 1.20 ------------------------------ Cable connections: You must connect the DB9/Lemo data cable from your PC's serial port to Port 2 of the 4700 and connect the small power plug to the Office Supply Module. Software updates: o Various enhancements to the RTK engine aimed an improving initialization performance and reliability. Some of these updates are designed to improve initialization performance under condition of canopy (heavy multipath distortion), which is a difficult environment. o Further improvements have been made to the Trimble Proprietary L2 signal tracking which increases L2 sensitivity and measurement accuracy, and decreases acquisition time, o Fix problem when using RTS/CTS on port 3 with an external radio. If the radio was not connected while the CMR output was enabled on port 3, then the port 1 connection to the TSC1 handheld would fail. o Add 'event marker count' display under control/event markers menu when using the 'Trimble Remote Controller' PC program. o Enable output of RTCM and CMR at the same time on a single port. o Add support for reception of multiple base stations at an RTK rover. This requires TSC1 Survey Controller Version 7.01 or later, and allows selection of the base station CMR ID. o GGA output updated to NMEA Version 2.30. The message now contains new quality indicators which include RTK position modes. These must not be confused with the quality indicators in the Trimble GGK message. o Added 'antenna group' and 'antenna measurement method' fields for the interface used by the Configuration Toolbox PC program. o Flash the Full-green Power LED (can be either power LED) to Amber for 100 msecs when an external event is triggered. This is only supported on the 4700. o Fully support RTCM V2.2 for RTK types 18, 19, 20 and 21. o Add event marker output records to the RT 17 streamed output. 4700 Communications Processor Version 1.42 ------------------------------------------ The Communications software upgrade is ONLY necessary for 4700 units that have an internal radio. Cable connections: Same as for the 4700 GPS Receiver upgrade given above. Software updates: o Fixes the inability to receive CMR messages at the rover when the base is receiving more than 9 satellites. o Fixes a problem which caused degraded radio reception when the rover was in close proximity to a base TrimMarkII/IIe transmitter. o Add the ability to change the "over-the-air baud rate" via a the TSC1 handheld at the base and rover (Survey Controller Version 7.00 and above). o Add the ability to read and set the base radio type at the base (supported types: TrimTalk at 4800 baud; TrimTalk at 9600 baud; and TrimMarkII/IIe) (Survey Controller Version 7.00 and above). 4800 GPS Receiver Version 1.20 ------------------------------ Cable connections: You must connect the DB9/Lemo data cable from your PC's serial port to Port 2 of the 4800 and connect the small power plug to the Office Supply Module. See the 4800 Operation Manual for further instructions and Figures. Software updates: o Various enhancements to the RTK engine aimed an improving initialization performance and reliability. Some of these updates are designed to improve initialization performance under condition of canopy (heavy multipath distortion), which is a difficult environment. o Further improvements have been made to the Trimble Proprietary L2 signal tracking which increases L2 sensitivity and measurement accuracy, and decreases acquisition time, o Add 'event marker count' display under control/event markers menu when using the 'Trimble Remote Controller' PC program. o Enable output of RTCM and CMR at the same time on a single port. o Add support for reception of multiple base stations at an RTK rover.

Cable connections: You must connect the DB9/Lemo data cable from your PC serial port to Port 3 of the 4800 (without connecting the small power plug to the Office Supply Module). In addition, unless the 4800 is being powered by a pole battery, power must be supplied to Port 2, using either another data cable with the Office Supply Module (Figure 2-7) or an external battery (Figure 2-6). See the 4800 Operation Manual for further instructions and Figures. Software updates: o Fixes the inability to receive CMR messages at the rover when the base is receiving more than 9 satellites. o Fixes a problem which caused degraded radio reception when the rover was in close proximity to a base TrimMarkII/IIe transmitter. o Add the ability to change the "over-the-air baud rate" via a the TSC1 handheld at the base and rover (Survey Controller Version 7.00 and above). o Add the ability to read and set the base radio type at the base (supported types: TrimTalk at 4800 baud; TrimTalk at 9600 baud; and TrimMarkII/IIe) (Survey Controller Version 7.00 and above). Having Difficulty Connecting to the 4700/4800? ---------------------------------------------- If WinFLASH cannot establish a connection to your receiver, as indicated by one of several messages, first carefully check the cable connections. These are described above in the sections "Cable connections" for the GPS Receiver update, and the Communications Processor update. Make sure that the GPS receiver is powered up (green LED on). The following may also solve the problem: o Close any other active applications, one of which may be already using the serial port. Exit WinFLASH and restart. o Check that you have specified the correct PC Comms Port, 1 or 2. o Although unlikely, an output may be enabled on the GPS port 2 which is preventing the WinFLASH connection. This can be disabled by cold booting the GPS receiver as follows: - Power down the GPS receiver using the power key. - Press the key to power up, and HOLD DOWN the key (do not release) until the red satellite LED turns full on (about 30 seconds). - Release the key - the GPS receiver will power down. - Power on the receiver in the usual way by pressing the power key.
