Setting up the unit (see page 5)

Attaching the Antenna

You can attach the antenna in one of two ways:

•

•

Attaching the antenna directly to the antenna port on the bottom of the unit

with the antenna vertical and pointing downward (left photo in Figure 3)

Attaching the antenna bracket to the unit and then attaching the antenna to the port at the end of the bracket with the antenna vertical and pointing

upward (right photo in Figure 3)

Figure 3: Antenna installation options

Note: The antenna bracket offers an alternative solution in situations where installing

the antenna on the bottom of the unit may not provide suitable reception, such as where a small increase in antenna height has a noticeable effect on reception.

To install the antenna directly into the unit:

1.

On the bottom of the unit remove the rubber cap covering the antenna port.

2.

Screw the antenna into the antenna port until snug. Do not overtighten.

To install the antenna using the antenna bracket:

1.

Align the bracket to fit into the recessed area on the bottom of the unit (as shown at right).

2.

Using the two thumbscrews on the bracket secure the bracket to the unit. Do not overtighten.

3.

Attach the bracket’s antenna cable to the unit’s antenna port.

4.

Screw the antenna into the bracket’s antenna port until snug. Do not overtighten.

Connecting to a Power Source

The S320 power cable has a two-pin circular connector at one end and two clamps at the other end (red clamp positive and black clamp negative).

Note: The power cable is included with the two-unit base/rover kit; it is not included in

the single-unit kit. See Table 1 on page 2 for more information on the parts included in

each kit.

To connect the power cable:

• Line up the red dot on the power cable end with the red dot on the power port and press into place.

Note: Applying external power does not charge the Li-ion batteries in the battery

trays. You must use a suitable battery charger to charge the batteries.

Setting Up the Unit

Figure 5 shows a typical setup for both a base station unit and a rover unit (tripod and

pole mount not included, data collector optional).

The antenna in Figure 5 is connected to the bottom of the unit; you have the option of

attaching the antenna to the antenna bracket so the antenna faces upward. See

“Attaching the Antenna” on page 4 for more information on attaching the antenna.
