ID RESISTANCE VALUE ASSIGNMENT
The ID resistors used with the 34825 are standard 1%
resistors.
Table 22 lists the complete 32 ID resistor
assignment. The ones with the assigned functions filled are
the ones that are already used with special functions. The
ones reserved can be assigned to other functions.
The remote control architecture is illustrated in Figure 26.
The recommended resistors for the remote control resistor
network are given in Table 23.
