 Wireless Connection:
Using the Juniper Allegro CE/RCS, a built-in radio modem and internal antenna is
included which permits wireless communication with the robotic total station when using the RM2410 radio. This
wireless connection is through the Leica propriety radio and does not involve Bluetooth per the Comm Setup
screen. The Comm port for the internal radio on the Allegro is COM 3. For one-man operation, the pole and prism
become “freed” from wire connection and can be placed anywhere for a shot or reading, with the process driven
“remotely” by the data collector communicating with the robotic total station.
Settings/Search
 EDM Mode:
Available methods are Standard (1.5 to 2 seconds), Fast, and Reflectorless. In all modes of data
collection, you are in “Rapid Tracking” mode. Clicking that icon goes to the “No Distance” or “Tracking Only
Mode” (no distance measurements). Avoiding taking distance measurements will save battery usage. So the “Dist”
button refers to the selectable mode you will “go to,” not the mode you are currently in. In Rapid Tracking mode,
the store icon will always take a “Rapid Tracking” shot, and pressing enter will take a Rapid Tracking shot if Enter
is configured to Store only (to mimic the store icon). Pressing the read icon will always cause configured reading to
be taken, as will Enter when set to Read and Store. The next figure shows the Rapid Tracking mode, which follows
the movement of the prism by taking rapid distance measurements, much like RTK GPS.
 Foresight/Backsight Prism Offset
: This drop down menu provides a list of standard prism offsets. Note that Leica
prisms default zero to equate to -34.4 mm. So a prism offset of 34.4 equals a zero “net” offset. Whenever a prism
constant is changed, a note is written to the raw (RW5) file. When you select one of the prisms from the list (Circle,
Mini, etc), the value that is shown in parenthesis is the actual value sent to the instrument. i.e. 0.0 for Circular, 17.5
for Mini. If you select "30mm" or "40mm", we send - 4.4 and 5.6 respectively (30-34.4 and 40- 34.4). The user
may also type in any value they choose. In this case, we will send that value exactly, unmodified, to the instrument.
