Series Installation & Start-Up

Step 2—Install the Antenna
To minimize radio frequency interference, the antenna should be
mounted at least nine inches (> 23 cm) from the connected device(s),
sensors and other components of the system. Additional information
on antenna selection and installation is provided in the
DataMover
ESS Series User’s Guide
.
Step 3—Measure & Connect Primary Power
The primary power at the transceiver’s power connector must be
within 10.5–30 Vdc and be capable of continuously providing up to
580 mA. A power connector with screw-terminals is provided with
each unit. Strip the wire leads to 6 mm (0.25"). Be sure to observe
proper polarity as shown in
Figure 1
with the positive lead (

) on the
left. If the transceiver is to be powered at voltages of 28 Vdc or higher,
please review the
User’s Guide
for important recommendations.

Polarity: Left +, Right –
The transceiver must be used only with negative-ground
systems. Make sure the polarity of the power source is
correct.
Review complete power requirements in the
User’s Guide, Part No. MAN.ESS-MAN.
The power supply used with the transceiver should be equipped with
overload protection (NEC Class 2 rating), to protect against a short cir-
cuit between its output terminals and the transceiver power connector.
NOTE:
It typically takes about 30 seconds for the transceiver to power
up, and about 20 to associate with another unit.
Step 4—Review the Transceiver’s Configuration
Two essential settings for the transceiver should be known before
placing the unit into service. They are:
Wire Ports
Lead
Screws (2)
