MDS 4310 QUICK START GUIDE
Below are the basic steps for installing the MDS 4310 (350—512 MHz) Data Transceiver. The infor-
mation in parentheses indicates the chapters in this manual where detailed explanations are found.
1. Verify radio set-up parameters. (Chapters 2 & 3)
Check the test data sheets packed with the transceiver to be sure the radio is properly configured
for the intended application. Check especially for these items:
• Proper configuration of software selectable settings such as, CTS delay, soft carrier dekey
(SCD), squelch tail eliminator (STE), time-out timer (TOT) and PTT delay. Chapter 3 gives
instructions for setting these parameters.
• Transmit and Receive frequencies.
(Should be the same as those listed on the station license.)
• Transmitter RF power output.
• Loopback Code.
(Default loopback code consists of the last four digits of the radio’s serial number.)
• Transmit modulation and audio input characteristics.
• Modem speed (if radio is modem-equipped).
2. Securely mount the transceiver. (Chapter 2)
• Use the MDS supplied mounting brackets and four screws or bolts (fasteners not provided).
• Choose a mounting location that allows easy access to the connectors on the end of the radio
and allows an unobstructed view of the LED status indicators.
3. Install and connect the antenna system to the radio. (Chapter 2)
• Use good quality, low loss coaxial cable.
• Keep the antenna feedline as short as possible.
• Avoid sharp bends in the coaxial cable.
• Preset the antenna in the direction of the master station.
• Properly waterproof the antenna connector.
4. Connect and apply DC power to the radio. (Chapter 2)
• Set supply voltage to a nominal 13.8 volts.
• Observe polarity.
• Power cord must be properly fused (3 Amperes).
• Plug in the power plug and tighten the retaining screw.
5. Verify radio communications by observing the LED display. (Chapter 2)
• See Tables 2-2 and 2-3 for interpretation of status LEDs.
• Refine the antenna heading by using a DC voltmeter or Hand-Held Terminal (HHT) to measure
the radio’s received signal (RSSI).
6. Connect the data equipment to the radio INTERFACE connector. (Chapter 2)
• Connection must be made with a DB-25 Male (25 pin) connector.
• Connect only the required pins. Do not use a straight-through RS-232 cable with all pins wired.
• Verify the equipment connected to the INTERFACE connector is configured as DTE. The radio
is configured as DCE (data communications equipment).
• Pin connections for the INTERFACE connector are summarized in Table 2-1.
