3.4 Getting Started
3.4.1 Radio Interconnect
Before taking any actions from the control program with an STR-1700 radio, the
radio must be connected to a primary power source and to the PC via a special
programming interface cable and adapter. The following figure depicts the
required interconnects.

FIGURE 3-1 RADIO TO PC INTERCONNECT CONFIGURATION
The 13.6 VDC power supply need only support the radio operation in a quiescent
mode (i.e., < 0.7 A). The power up sequence of the radio versus the PC is not
critical.
The interconnect from the radio to the PC is via an interface cable and
adapter provided with the software (SRI P/N 50-STR1700-200). The cable
consists of a DB9 female connection on one end and an RG45 male connector on
the other end. The DB9 end should be plugged into any standard serial
communications port on the PC. DB9 to DB25 adapters may be utilized as
required.
The interface adapter accepts the RG45 connection on one side and interfaces
with the STR-1700 female DB-25 front panel connector on the other. The
adapter also includes an LED and a momentary push button switch on the sides
of the plastic housing.
3.4.2 Power-on Sequence
Once the above configuration has been established, the primary power supply
and PC should be powered on and initialized. When the primary power is
activated to the STR-1700, the LED on the side of the programming interface
adapter should illuminate. This indicates that the radio has successfully
powered up in an “ON” condition.
If the LED fails to illuminate within two (2) seconds, the user should attempt
to establish an “ON” condition by momentarily activating the push button on
the side of the programming interface adapter and then releasing it. If a
