CrossBows

CrossBows

The device setup for the CrossBows interface should be set to specify CrossBows (see the "Special Device Modifier" below)::

In CrossBows, ensure the following options are set:

Start Crossbows, go into "Tools/Options"

In the "general" tab set the following:

BASExt=BAS (this specifies the extension for BAS responses – Rx-Universe requires this to be BAS, the default is LMS)

LOHComms=0 (this disables the interface with RxServer, which is usually ON by default)

To use the TOKEN label in the LDS file to control the click fee if an order prescription has been changed, do the following:

In the "Advanced" tab, set the following:

 in the DESIGNSETTING-1 paragraph, add ForceSettings=0 and change BILLOK=0 it should appear as follows:

[DESIGNSETTING-1]
SMDMAX=10;10;10;10
ForceSettings=0
BILLOK=0

The default is :

[DESIGNSETTING-1]
SMDMAX=10;10;10;10
BILLOK=1

To set the input directory for the LDS files, go to "File\Input File"  and set to the folder where LDS files will be sent from Rx-Universe, and picked up by CrossBows.

To set the output directory for the LMS and SDF files, go to "File\Output file" and set to the folder where LMS and SDF files will be stored.  Note that for SDF files, you should use URL naming conventions, to ensure the devices can find the file when sent in LDPATH.

Older Crossbows will have the above information in a file called RxInfo.ini.  

The RxInfo.ini file is located in different folders depending on the version of Windows:

Windows 10 - the RxInfo.ini file is found in c:\users\omics.omics1\AppData\Roaming\CrossBows\CrossBowsRx.  Note that the Rxinfo.ini will be in the folder of the user that installed the Crossbows app

Windows 7 - the RXInfo.ini file is found in C:\Program Data\Crossbows\CrossbowsRX. The C:\Program Data folder is normally hidden, so you may have to select “Show hidden files and folders” in the Folder Options.

Older versions of Windows - one of the following folders:

C:\Program Files\Crossbows\CrossbowsRX   
C:\Documents and Settings\All Users\Application Data\Crossbows\CrossbowsRX              
C:\Program Data\Crossbows\CrossbowsRX 

Custom V Design Options

There is an option on the Crossbows software to allow a variable inset, and this only applies to the Custom V design.  When this is enabled in the CrossBows calculator (from the Tools|Options menu), then for Custom V, the inset will be calculated based on variables like NWD, lens power, BVD etc. In this case the LMS should send the NWD, IPD, SPH, CYL, AX and BVD.  If some values are missing, then defaults will be used or calculated.  

The manual inset is to cater for the eye doctor who wants to have a specific inset for his or her patient and in this case  the ERNRIN value should be used to directly specify the inset required.  From the CrossBows documentation:

When creating an uncut order for a Crossbows design where variable inset is allowed, the lens style must be set to allow the NPD to be entered:

When entering an uncut with no frame measurements, the decentration and inset can be entered in the appropriate fields, as illustrated:

In the above example, the design is requested to be decentered 3mm from the center of the blank, and the ADD circle to be decentered 2mm from the PRP. 

The inset is then sent as ERNRIN to the Crossbows calculator.  Note, you may need to edit the labels sent to Crossbows to include ERNRIN, in the LDI file (see Use of LDI (initialization files) with Digital Vendors)

For the automatic corridor selection the length of the corridor is returned in CORRLEN, the inset is returned in ERNRIN.
