Web Interface

The XPS controller is running a web server. Within the X1A subnet it is known under the address stxmi-XPS or stxmo-XPS. (If you are tunneling the pertaining port through SSH, you can of course reach this from anywhere). For moving motors without changing the XPS' configuration, it is enough to log in as User micros with the default password. For the unexperienced user, we recommend to only use the FRONT PANEL Move (see Fig 14.1).

For enabled motors you can perform absolute or relative moves. However, you need to pay attention to two things:

1. The positions and velocities are given in mm (mm/s) rather than $\mu$m.
2. The direction sense is native to each stage and does not always comply with the STXM coordinate system (1.2). Table 14.1 lists, how the direction senses relate to each other, and the direction which the buttons (<>) will move in.

Table 14.1: Direction sense of motorized stages

Stage	$<$	$>$	native direction	rel. to STXM
XSTG	O	I	inboard	-1
YSTG	D	U	up	+1
XDET	O	I	inboard	-1
YDET	D	U	up	+1
ZDET	D	U	upstream	-1
ZOSA	U	D	downstream	+1

Also, note that the soft limits we use in STXM are only activated, when sm_server is running.
