This command lets the user set a position, in millimeters - absolute, which will toggle the TTL-level SYNC output when the stage crosses that position. When ''ENSYNC'' is issued, the SYNC output is reset low.  Whenever the stage crosses the ''ENSYNC'' position, the output will toggle low to high and if crossed again, from high to low.  ''ENSYNC'' will only work with one axis at a time, either X or Y and depends on how ''JP1'' is jumped (''JP4'' on Tiger/LX cards). 

Note that the position "wraps" every 2<sup>24</sup> encoder counts, which is only a concern for very long travel stages and/or for very fine encoders.

See the [[:scan_module|SCAN MODULE]] documentation for more details.

== Minus ==
If you send the command with the minus sign ''ES <axis>-'' it will set the SYNC output to low.

This feature is available on MS2000 v9.52 and Tiger v3.46 firmware.

== On MS2000 ==

The TTL SYNC output is available on SV1 Pin 7.

Contact ASI for additional details on these modifications.

== On Tiger ==
Dual Axis Card Rev F3 and above required (TGDCM2). The SYNC signal is routed to the backplane (C13 or C14) and is also available directly from JP4 for LX cards. Additional [[:tiger_programmable_logic_card|hardware]] is needed to expose the signal.

Contact ASI for additional details on these modifications.

**Warning:** prior to MS-2000 v9.52, ES <axis>? was expressed in encoder counts, not millimeters.

**Warning:** prior to MS-2000 v9.55, ES <axis>=# would set the value in encoder counts, not millimeters. This __only applies to the CRISP focus axis__. Other axes are still set in millimeters.
