[. . . ] While the internal battery is being charged from an external source the indicator changes from empty to full. If the voltage from the external source is too low to charge the internal battery, an X appears over the battery indicator. Note ­ The radio-modem can only be used as a base while using the ATS protocol. Battery indicator Network number Operating mode Status menu screen: (2) Firmware screen A second Status menu screen, the Firmware screen, displays the version and date of the firmware that is loaded on the radio-modem. Status menu screen: (3) Serial Number screen A third Status menu screen, the Serial Number screen, displays the serial number of the radio-modem. Status menu screen: (4) Country Code screen A fourth Status menu screen, the Country Code screen, displays the country of use that the radio-modem is configured for. Note ­ You cannot change the country code. 42. 2 Protocol menu Use this menu to set the protocol that the SNB900 radio-modem is to use. Changing the protocol changes the menus that appear on the display of the SNB900 radio-modem. The SNB900 radio-modem can be set to the following protocols: · CMR ­ the radio will be used in a GPS radio network to generate or receive CMR corrections ATS ­ the radio will be used with an ATS for machine positioning applications. · SNB900 Radio-Modem User Guide 27 4 ATS Configuration and Installation · Easy IP ­ the radio will be used in a GPS radio network to generate or receive CMR corrections as well as provide two-way data transfer between the office and machines. 42. 3 Network menu Use this menu to control which network the radio-modem is operating on. By choosing a unique hopping pattern, you can reduce the likelihood of interference from nearby transmitters. Note ­ If a GPS radio network is operating on the same site, the ATS radio network should be configured to operate on a different network. 42. 4 ATS Port menu Use this menu to set which port is connected to the ATS. The SNB900 radio-modem can be connected to the ATS using either the Lemo or Modem port. When the ATS port is selected from the front panel, the unit automatically configures the port to 9600 baud rate, 8 data bits, no parity, and 1 stop bit. 4. 3 Installing the SNB900 radio-modem as an ATS base When the radio-modem is used as an ATS base radio, it transmits positioning information from the ATS to an earthmoving machine. To install the radio-modem as an ATS base when using a Trimble ACU to start the ATS: 1. Attach the SNB900 radio-modem on a leg of the tripod that the ATS is setup on using the tripod clip on the bottom of the SNB900. Connect the SNB900 radio-modem to the ATS using the following parts as shown in the image below: a. Cable ­ Adapter T-Connector, Hirose-Hirose-Hirose (P/N 571202312) Cable ­ 0. 75m-1. 75m, Hirose to Hirose Spiral Cable (P/N 571208068) 4-pin Hirose to 26-pin serial cable (P/N 53007007) Cable ­ 3. 0m, Car Battery to Hirose (P/N 571202326) 28 SNB900 Radio-Modem User Guide ATS Configuration and Installation 4 Figure 4. 1 ATS setup with an ACU 3. Start the ATS using SCS900. To install the radio-modem as an ATS base when using a Trimble TSCe to start the ATS: 1. Attach the SNB900radio-modem on a leg of the tripod that the ATS is setup on using the tripod clip on the bottom of the SNB900 radio-modem. Connect the TSCe to the ATS using the following parts as shown in the image below: a. Cable ­ Adapter T-Connector, Hirose-Hirose-Hirose (P/N 571202312) Cable ­ 0. 75m-1. 75m, Hirose to Hirose Spiral Cable (P/N 571208068) 4-pin Hirose to 26-pin serial cable (P/N 53007007) Cable ­ 3. 0m, Car Battery to Hirose (P/N 571202326) SNB900 Radio-Modem User Guide 29 4 ATS Configuration and Installation Figure 4. 2 ATS setup with a TSCe 3. Disconnect the TSCe and connect the cable (P/N 530007007) to the SNB900. To install the radio-modem as an ATS base when using a Trimble TSC2 to start the ATS: 1. Attach the SNB900 on a leg of the tripod that the ATS is setup on using the tripod clip on the bottom of the SNB900. [. . . ] However, it is the elevation and orientation of the rover antenna that determines which antenna--the 5 dB or the 0 dB antenna--provides the stronger signal. 72 SNB900 Radio-Modem User Guide Antenna Details 7 73. 1 Energy patterns Figure 7. 1 shows the radiated energy patterns of an omni-directional antenna, viewed from above.
