Figure 26 - GTI Unit DIP Switch Orientation
In the left-hand DIP switch (SW2), switch sections 1 through 4 are set to identify the type of telephone line to be connected to the GTI unit, switch section 5 is not used, and switch sections 6 through 8 are used to set the baud rate for the serial data port to the GTI Configurator terminal.
In the right-hand DIP switch (SW1), switch sections 1 through 6 are set to match the radio channel number connected to the GTI unit (this will also be the line number of the telephone line connected to that GTI unit), and switch sections 7 and 8 are not used.
Table 5 summarizes the defined switch settings for both DIP switches. Switch combinations not shown are not supported by the ELI option.
