III. Installation  
A. Mounting to Monochromator  
The filter assembly is 3/4 of an inch thick. Therefore, if using a light source that is designed to  
mount directly on the entrance slit housing and to focus the light on the entrance slit, it is  
recommended that the filter assembly be mounted on the exit slit housing. If it is necessary to  
install or change filters, do so before mounting the filter wheel to the SpectraPro™ (refer to step C).  
The filter assembly is designed to mount directly to the SpectraPro™ slit housings or to be mounted  
between the light source or detector and the slit housing. The filter assembly is attached to the slit  
housing with three screws. The fourth screw is not used with the filter assembly. Assure that the (3)  
8-32 mounting screws extend approximately 0.25 inch (6mm) beyond the filter assembly housing.  
Orient the filter assembly so that the aperture slot is vertical and the motor is away from the  
instrument housing. Mount the filter assembly or light source/detector to the desired slit housing  
with (3) 8-32 screws.  
B. Connecting Control Unit  
Each control unit must be connected to an AC line of 115 vac. There is also a cable with a 15 pin  
connector attached to each control unit which must be connected to the filter wheel assemblies. For  
RS-232 operation of the filter assemblies, each control unit must be connected to separate RS-232  
ports of a computer or terminal. Acton Research Corporation offers the following connecting cables:  
CC-499-1  
CC-499-2  
CC-499-3  
Cable for IBM-PC or XT compatible computers,  
25 pin female connector to 9 pin male connector  
Cable for IBM-PC/AT or compatible computer,  
9 pin female connector to 9 pin male connector  
Cable for computer terminal  
25 pin male connector to 9 pin male connector  
If none of the above cable assemblies are compatible with your computer or terminal, contact Acton  
Research Corporation for a custom cable or one may be constructed using a standard DE-9P  
connector at the filter controller end with the following connections:

C. Installing and Changing Filters  
To install or remove filters or samples, the following procedure is recommended:  
1)  
2)  
3)  
If the filter assembly is mounted to the SpectraPro™, remove it and disconnect the cable, if  
attached.  
Place the filter assembly on a clean surface with the motor down. Refer to  
Figure 1.  
Using the 1/16" allen wrench supplied, remove the eight screws securing the cover plate to  
the filter assembly (refer to Figure 1). While pushing on the end of the shaft with a pencil,  
carefully remove the cover plate by lifting straight off the shaft. Caution: A spacer is located  
on the filter wheel shaft between the filter wheel and cover. If this spacer comes off with the  
cover, place it back onto the shaft. Refer to Figure 2.  
4)  
5)  
The six filter positions are now visible, refer to Figure 2. The filters are held in with split rings.  
Determine the filters to be removed or the location for the filters to be installed. The filter  
positions are marked 1 thru 6 on the wheel. Remove the split rings. Remove or install filters  
as required. Replace the split ring assuring it is pushed firmly against the filters.  
Assure that the spacer is on the filter wheel shaft and attach the cover plate with the eight  
screws. The filter assembly is now ready for mounting to the SpectraPro™.

IV. Operation  
A. Remote Operation from Controller Unit  
The filter positions of each filter wheel can be controlled using the thumbwheel switches on the  
controller modules supplied with the filter assemblies. Connect the motor drive cable of the  
controller to the motor connector of the filter wheel for each unit. Connect the control unit to an AC  
line of the voltage listed on the back of the controller. The positions 0 - 6 may then be selected by  
this switch.  
B. Operation with RS-232 Computer or Terminal  
Connect the motor drive of the control unit to the filter wheel and the RS-232 output of the control  
unit to an RS-232 port of a computer or terminal. See section III-B for cable installation instructions.  
The filter wheel with controller responds to commands from the computer or terminal in the form of  
ASCII strings. The following two commands are used for controlling the filter position:  
FILTER  
Controls the filter position and is used as follows:  
3 FILTER <enter> sets filter wheel to position 3. Filter  
positions 1 - 6 may be selected. Note that there must be a  
after the number and the command must be terminated  
with the enter or carriage return key. The filter will go  
to the specified position in the direction which  
requires the shortest move. When the move is  
complete, the controller will respond with OK followed  
by carriage return and line feed (hex AXCII sequence  
20 6F 6B of OA). Also, the default condition is to echo each  
character that is sent to the controller. If no echo is  
desired, the command NO-ECHO will suppress the echo.  
The command ECHO will return the controller to the  
default echo state.  
?FILTER  
FHOME  
Returns the current filter position. Typing ?FILTER <enter>  
will cause the current filter position to be returned to the  
computer and displayed.  
Initializes the filter wheel to the first filter position.  
This command is automatically executed at power-up.  
The filter wheel controller keeps track of filter  
position as long as power is applied. It should not be  
necessary to execute this command under normal  
circumstances, although it is available if desired. This  
command follows the same format as in FILTER above  
for entry and response.

C. IEEE -488 Interface Option for Filter Controllers  
The IEEE-488 interface option allows control of ARC Filter Control unit from the IEEE-488 bus. All  
of the commands and status requests described in Section B - Operation with RS-232 Computer or  
Terminal - are available through the IEEE-488 option. The following standard interface functions are  
provided:  
SH1, AH1, T2, L2, SR1, RL1 (NOTE: The local lockout command  
is not accepted but the front panel is automatically locked out when  
in remote), PP0, DC0, C0  
The GPIB device identifier or address may be sent by dip switches on the interface board. The  
switches are accessible on the bottom of the control unit by removing screws to the access plate.  
The factory set device address is 10. The command ?ID will report back the current device address.  
The following table shows the function of each switch position:  
S1-1 on = address 1 decimal, off = address 0  
S1-2 on = address 2 decimal, off = address 0  
S1-3 on = address 4 decimal, off = address 0  
S1-4 on = address 8 decimal, off = address 0  
S1-5 on = address 16 decimal, off = address 0  
S1-6 factory set to on  
S1-7 factory set to off  
S1-8 factory set to off  
S1-9 factory set to on  
S1-10 factory set to on  
The last byte of each command string to the Filter Control unit must be a <CR> (hex OD). The end  
message (EOI line) is accepted but not required. When the SpectraPro™ is a talker, each string  
sent back to the controller ends with a <LF> (hex 0A) with the EOI line set.  
The Filter Control unit will issue a service request based upon the contents of the service request  
mask which is set by the SET-MASK command and read by the ?MASK command. The bits of the  
mask are as follows:  
bit 0 previously sent command is complete  
bit 1 previous command generated an error  
bit 7 previous command generated a response which is  
now ready to be sent  
The default value for the service request mask is ø, therefore, no service request is generated. To  
change the mask to generate a service request on error or response ready, for example, issue the  
command 130 SET-MASK <CR>. This new value is reset to the default value on reset or power-up.  
The Filter Control unit responds to a serial poll with a status byte that uses the same bit pattern as  
the service request mask shown above.
