The 80190-759-02 universal encoder interface is functionally identical to the
80190-759-01 with the addition of conformal coating. The universal encoder
interface is configured via jumpers installed on the 12-position header J4. The
header has three positions labeled ‘Park’ and used to store the jumpers when
indicated as “Removed” in the table below. Each function is selected by moving
its corresponding jumper from the ‘park’ location to the selected function
location if labeled “Installed”. Table 14
describes the functions available.
Figure 137 - Universal Encoder Board
Connections to the universal encoder interface occur via a 1492-IFM20F
interface module. The connections to the IFM are detailed below.
ATTENTION: Removing the Universal Encoder Interface with active control
power may damage the board. Disconnect the control power before
removing the board.
