Client Access License (CAL)
An application allowing multiple users to share a single 
operation system requires the standard Microsoft 
Windows server licenses. In addition to Windows 
Server Client Access License, Remote Desktop 
Services Client Access License (RDS CAL) is necessary 
for each end user or each device to access Windows 
server. When using Windows Multipoint Server, 
Windows MultiPoint Server 2011 CAL is also necessary. 
For details of Microsoft multiple user licenses, see the 
Microsoft website.
1. When the host computer OS is Windows XP, Win-
dows Vista or Windows 7
For Windows XP, Windows Vista and Windows 7, only a 
single projector can run the thin client function. While 
using the desktop of host computer, you cannot use the 
thin client function on the projector.
2. When the host computer OS is Windows Server
2008 R2
Windows Server requests Client Access License (CAL). 
To access the host computer from a thin client 
computer or projector, two types of CAL are necessary: 
“Windows Server CAL” and “Windows Remote Desktop 
Service (RDS) CAL”. “Windows Server CAL” offers two 
types of license system.
User CAL
With User CAL, you purchase CALs according to the 
number of users regardless of the number of thin client 
computers or projectors. User CAL is, therefore, 
recommended in the case that the number of system 
administrators or operators who operate thin client 
computers or projectors at multiple sites is smaller than 
that of the thin client computers or projectors.
In the example above, the following licenses are 
necessary.
 Windows Server CAL (User CAL) x 2
 Windows RDS CAL x 2Device CAL
With Device CAL, you purchase CALs according to the 
number of devices accessing to the host, regardless of 
the number of users who access the host via thin client 
computer or projector. Therefore Device CAL is 
recommended for the case that multiple operators 
share a thin client computer or projector.
In the example above, the following licenses are 
necessary.
 Windows Server CAL (Device CAL) x 4

3. When the host computer OS is Windows
MultiPoint Server
The concept of Windows MultiPoint Server is basically 
the same as that of Windows Server 2008 R2. It 
requires Windows MultiPoint Server CAL instead of 
Windows RDS CAL. Therefore, Windows Server CAL 
and Windows MultiPoint Server CAL are necessary for 
each user or device. When you use the desktop of host 
computer as one of computer terminals, Windows 
MultiPoint Server will also request a Windows Server 
CAL and Windows MultiPoint Server CAL for the 
desktop of host computer.
(Example 1)
When two users operate four computers or projectors 
as well as the desktop of host computer
 Windows Server CAL (User CAL) x 2
 Windows MultiPoint Server CAL x 2
(Example 2)
When six users operate four computers or projectors as 
well as the desktop of host computer
 Windows Server CAL (Device CAL) x 4
 Windows MultiPoint Server CAL x 4
