Pot
R14 Phase adjust between sine and cosine signals
R15 Balance for encoder cosine signal
R16 Gain adjust for encoder cosine signal
R17 Balance for encoder sine signal
R18 Gain adjust for encoder sine signal

1.4.8. Output Options

The following Digital Differential Factory options are available; refer to Figure 1-12,
Figure 1-13, Figure 1-14, and Figure 1-15. All four of these options provide RS-422
differential square wave output signals produced after multiplication. Options 1-3 add
additional outputs providing RS-422 signals from the un-multiplied input signals
Table 1-8. Digital Differential Factory Options
Option Code
NONE Differential square wave sine / cosine multiplied signals (standard)
-1 Differential square wave output of un-multiplied sine signal
-2 Differential square wave output of un-multiplied sine and cosine
signals
-3 Differential square wave output of un-multiplied sine, cosine and
marker (unqualified) signals.
