 3.  To help receive pass data over the virtual COM port in a particular format, you can add 

extra prefix or postfix characters to the data that is sent, using 

ComPortPrefix

 or 

ComPortPostfix

 settings. You can also set 

ComPortPassMode=1

 and choose to 

Extract only part of the pass data

 using the same settings used to manipulate pass data 

sent over keyboard emulation, but this time starting the settings with 

ComPortPass...

 

rather than 

KBPass...

.

 4.  Now reboot, to enable the COM port interface. You can do this by disconnecting the 

USB cable.

 5.  When you reconnect the VTAP100 it will still appear as a mass storage device on your PC, 

though perhaps assigned to a different drive letter because its USB device ID has changed. 

(If you missed step 1, check your Device Manager. On Windows 7 VTAP100 may appear 

under 'Other devices'. On Windows 10 it may be a new USB Serial Device under 'Ports 

(COM & LPT)'. Associate it with the correct driver 

VTAP100.inf

 in the VTAP100 file 

system.) Pass data will now be sent over the COM port automatically, when it is received.

Note:

 If you would rather receive pass and status data only in response to a request over 

the COM port refer to  the Advanced Configuration Guide and Commands Reference on 

how to 'Use the virtual COM port in passive mode'.

5.2 Using VTAP100 with Read-a-Card software

There are a number of steps needed before you will be able to use the VTAP100 as a 

proprietary reader recognised by Read-a-Card software. This gives you an expanded facility to 

check and manipulate data stored in passes, tags or cards. If you do not have Read-a-Card 

software, you can download the latest version from here: 

https://readacard.com/downloads/Read-a-Card.msi

Note:

 If your Read-a-Card software does not already have a PC-license, or an e-license from 

another connected reader, you will need to obtain a Read-a-Card e-license for your 

VTAP100.  

Contact Dot Origin about a Read-a-Card eLicense for your VTAP100

 quoting 

the ATCA number, which you can copy from 

BOOT.TXT

 on your VTAP100.
