70-STR1800-00 Rev K STR-1800 O&M Manual Figure 6 Field Control Software Initial Screen The Factory version requires cabling as noted in Figure 5. Running the Factory (“GE Personnel”) version of the application provides a user interface screen as shown in Figure 7 below. The capability is similar to the above mode however additional functionality will require the Figure 5 cabling.
70-STR1800-00 Rev K STR-1800 O&M Manual If this is the first time either program is being utilized or if the operator has changed the PC’s serial communications port being utilized, the first action taken by the user should be to establish the correct port selection. This can be accomplished by doing a menu selection from the “Radio Comm Port” selection. After this action, the user may select “Get All”.
70-STR1800-00 Rev K STR-1800 O&M Manual 2) On initial power up or on any change of the frequency select lines into the radio, the target frequency setting may take up to 100 msec to obtain. 3) If push-to-talk is active at any time during the tuning period outlined in note 2 above, the tuning action will not complete until push-to-talk is removed and stay’s in a non-active condition for a period of 2 seconds.
