Terminal Connections
Table 4, Table 5, and Table 6 provide the pinout descriptions for the three connection
terminal strips found on the main PCB of the Digital Tone Remotes. Figure 14 shows the
relative position of the terminal strips to one another, and the order in which their pins are
numbered. Please note that the terminal designated TB2 is present only in the Model 284.
