5.0 STEP-BY-STEP INSTALLATION

In most cases, the steps given here are sufficient to install the trans-
ceiver. Refer to "INSTALLATION PLANNING" on Page 12 for addi-
tional details, as required.
1. Mount the transceiver. Attach the mounting brackets to the bottom
of the transceiver case (if not already attached), using the four 6-32
x 1/4 inch (6 mm) screws supplied. Mounting bracket dimensions
are shown in Figure 11 on Page 13. Secure the brackets to a flat,
grounded surface. (If a grounded surface is not available, run a
separate ground wire to the transceiver—see "Grounding
Considerations" on Page 16.)
2. Install the antenna and feedline. The antenna used with the radio
must be designed to operate in the radio's frequency band, and be
mounted in a location providing a clear path to the associated sta-
tion(s). At Remote sites, aim directional antennas toward the master
unit. Low loss coaxial feedline should be used and it should be kept
as short as possible.
3. Connect the data equipment. Connection may be made using
IP/Ethernet signaling, Serial protocols (RS-232/RS-485), or both.
• If an Ethernet device is to be used, connect it to the front panel
port next to the
ETHERNET
• If a serial device is to be used, connect it to
panel. The radio is hardwired as a DCE device. A straight-through
cable may be used in most applications.
NOTE:
Do not connect the radio's Ethernet port to a LAN with high traffic levels.
Excessive traffic will overload the port and cause it to be temporarily
disabled. In general, traffic levels above 4 Mbps are likely to cause port
shutdown. (Traffic limit is less than 4 Mbps with packet sizes smaller than
64 bytes.)
4. Connect primary power. Input power must be within 10.5 to 16
Vdc (SD4) or 10.0 to 30 Vdc (SD9), and capable of providing at
least 2.5 Amperes. A power connector with screw-terminals is pro-
vided with the unit (see Figure 14 on Page 16). Strip the wire leads
to 6 mm (1/4 inch) and insert them into the wire ports. Be sure to
observe proper polarity. Tighten the binding screws securely.
The unit is designed for use with negative-ground systems only.
CAUTION
The power supply should be equipped with overload protection
(NEC Class 2 rating), to protect against a short circuit between its
POSSIBLE
output terminals and the radio's power connector.
