External Antenna Setup

8.3. External Antenna Setup
The TRIUMPH-1 receiver can also be used with an external antenna. Follow the steps below to connect
an external antenna to TRIUMPH-1 and measure its offset.
1. Attach the antenna to a tripod or bipod and center it over the point at which data will be collected.
2. Measure the antenna height, as described in "Measure Antenna Height" on page 50.
3. Record the antenna height, point name, and start time in the field notes.
4. Attach the flexible RF cable from the external antenna to the antenna connector on the bottom
panel of the receiver.
The TRIUMPH-1 antenna default is set to Auto, allowing the receiver to detect automatically the available
antenna (whether internal or external). If you have changed this setting, or the receiver does not detect the
external antenna, use the procedure described on page 61 to set the External Antenna detection option.

8.4. External UHF Modem Setup

1. Connect the external modem to the receiver's serial port B using serial cable.
2. Attach power cable to modem to power it.

8.5. Collect Data

See the remaining sections in this chapter for more information on collecting data.
1. Turn on the receiver.
2. Once the receiver has locked on to eight or more satellites the SAT light will green.
3. A red color of POS LED indicates that the receiver has not solved a position. Four or more satel-
lites provide optimal positioning.
4. Once the red POS LED is green, the receiver has a position and surveying can begin; wait for
green light before beginning data collection. This ensures that the receiver has the correct date and
time, and is locked on to enough satellites to ensure good quality data.
The process of locking on to satellites normally takes less than one minute. In a new area, under
heavy tree canopy, or after resetting the receiver, it may take several minutes.
5. To begin collecting data, press and hold the FN key (for more than one second and less than five
seconds).
6. Release the FN key when the REC (recording) LED turns green. This indicates that a file has
opened and data collection has started. The REC LED blinks each time data is saved to the inter-
nal memory.
7. When finished, press and hold the FN key until the REC LED light goes out.
8. To turn off the receiver, press and hold the power key until all lights go out, then release.
