Keep the feedline as short as possible.• Preset directional antennas in the direction of desired transmission. 2. Connect the data equipment to the radio’s INTERFACE connector • Connection to the radio must be made with a DB-25 Male connector. Connections for typical sys-tems are shown below. • Connect only the required pins. Do not use a straight-through RS-232 cable with all pins wired.• Verify the data equipment is configured as DTE. (By default, the radio is configured as DCE.) The markup had a question about this figure. Please verify 3. Apply DC power to the radio (10–30 Vdc @ 1.5 A minimum) • Observe proper polarity. 4.
