21               A motor of S22 model and A controller of S6961 model are used for 
22 saw   1.1.2.1 the target ladder. The motor are attached at side of a xyz-stage of  
23               the target ladder. Two limit switches for negative and 
24               positive positions, and home switch are placed on the sides.     
25               The control box is located at a rack in front of SOS power supplies 
26               in Hall C as well as the  control boxes for the sieve slits. 
27               These have RS232C(3 wires) and are operated from hcpc10401
28               (pc104 board PC) remotely. Current positions and status 
29               are read out and stored in EPICS and data.

31               \section {Operation}
32               
33               You type {\bf tgt-control.tcl} and see the window of {\bf Target control 
34               for E01-011}. Target ladder has 6 holders in total. 
35               Items of Operation are \\

38               > 'Go home'  move to HOME switch,
39               > 'Go out' move ladder out from beamline,
40               > 'Go Tgt *' move target ladder to the number* holder. * is 1 - 6, 
41               > 'STOP!'    stop moving

44               \end{verbatim}
45               
46               You push the bottom of 'Go home' to move the ladder to the 
47               home switches for a zero-position adjustment. 
48               'Go home' searches for the home switch moving the ladder to 
49               the home switch, and then reset the zero position (+0.0000). 
50               You always have to move it from Home (+0.0000) to the positions 
51               in case of a power cycle (the first setup, a power down ...).
52               You have to check the positions on the screen and also check the position 
53               of a target holder by Camera of the viewer after moving. 
54               When push the bottom of 'STOP!', run program stops immediately. 
55               When you replace the ladder, you have to move the ladder out from 
56               beamline completely and have to move it behind the gate valve.  
57               Push the bottom of  'Go out' to move the ladder out.

61               These are values of positions from controllers.
