Typical RS/EIA-232 applications require the use of Pin 2 (receive
data—RXD and Pin 3 (transmit data—TXD). Some systems may require the
use of Pin 7 (Request-to-send—RTS). Figure 13 shows connection details for
the
DATA connector for EIA/RS-232 and EIA/RS-485, respectively.
If hardware flow control is desired, Pin 7 (RTS) and Pin 8 (CTS) may also be
connected. For a more detailed discussion of pin functions, see “Data Inter-
face Connections (DB-9F)” on page 69.

NOTE: The data cabling between the transceiver and the connected device should be
kept as short as possible. For EIA/RS-232 operation, the maximum recom-
mended cable length is 50 feet/15 meters.

4. Measure and install the primary power for the transceiver. It must be
within 6–30 Vdc (including transients) and be capable of providing 7.5
watts over this voltage range. (Typical current draw is 400 mA
@13.8 Vdc; 0.9 A @6 Vdc.) A power connector with screw-terminals is
provided with each unit. Strip the wire leads to 0.25˝/6 mm. Be sure to
observe proper polarity. The left pin is the positive input; the right is
negative. (See Figure 14.)
