The screws holding the brackets to the radio are
5
⁄16 inch (8 mm) long so as not
to damage the radio’s PC board when tightened. If these screws are replaced for
any reason, the new screws must not exceed this length.
2. Install the antenna and antenna feedline for the station. Antennas should be
mounted in the clear and in accordance with the manufacturer’s instructions.
Additional information on antennas and feedlines is contained in Section 4.4
( Page 10 ).
NOTE: Strong fields near the antenna can interfere with the operation of the
low level RTU circuits and change the reported values of the data
being monitored. For this reason, the antenna should be mounted at
least 10 feet (>3 meters) from the radio, RTU, sensors and other
components of the system.
3. Connect the data equipment to the transceiver’s DATA INTERFACE
connector. Use only the required pins for the application—. Typical
applications require the use of Pin 2 (received data—RXD), Pin 3 (transmit
data—TXD) and Pin 7 (Request to send—RTS).
Figure 13 shows a detailed
view of the DATA INTERFACE connector.
If hardware flow control is desired, Pin 4 (Sleep) and Pin 5 (signal ground)
are also required. A detailed chart of pin functions is provided in Table 11 on
page 39 .
