Set the baud rate for the RS-232 port on the GTI unit using DIP switch SW2 sections 6, 7, and 8 located on the right
side of the GTI unit. To get to the DIP switch after the GTI unit has been mounted in an EDACS repeater cabinet,
remove four screws in front and two in back. Then slide the GTI unit forward just enough to reach the DIP switch. If
there is enough slack in the connecting cables, it isn’t necessary to disconnect them or power from the GTI unit. The
layout of the DIP switch sections is shown in Figure 25. The DIP switch settings for various baud rates are shown in
Table 4. The recommended baud rate is 9600 bps. After you have set the DIP switch sections, press the RESET
button on the GTI unit to force it to read the new DIP switch settings.
