The RealPresence Collaboration Server (RMX) 1500 supports one card type: MPMx.
Table 21-2  RMX Time – Fields Properties
Field Description
GMT Date The date at Greenwich, UK.
Local Time The MCU’s local time settings, are calculated from the GMT Time and 
the GMT Offset.
GMT Time The MCU’s current GMT Time settings.
Select the Up or Down arrows to alter the GMT Time on the MCU.
GMT Offset The time zone difference between Greenwich and the MCU’s 
physical location in hours and minutes.
Select the Up or Down arrows to alter the GMT Offset time on the 
MCU. To enter a negative offset either type a minus in the hour box or 
use the down arrow and decrease the offset below zero.
Retrieve Client Time Click this button to automatically update the MCU’s GMT Date, Time 
and Offset to match that of the workstation.
Use NTP Server Select this check box to synchronize the time with up to three NTP 
servers. When selected, the manual GMT Date and GMT Time 
setting options are disabled. The GMT Offset fields are still active.
To implement this mode an external connection to an NTP server 
must be enabled.
Enter the IP addresses of the required NTP servers in order of 
precedence. 
The Status field indicates whether registration with the NTP Server 
failed or succeeded.
Note: TheCollaboration Server will not use a time source such as a 
Windows-based, W32Time service (SNTP) time service. Only full-
featured (below Stratum 16) NTP Servers are considered sufficiently 
reliable for high-accuracy timing environments.
Adjust Reservations 
Time
(Button)
Use this button to adjust the start time of all the reservations in one 
operation. For more information see "Adjusting the Start Times of all 
Reservations” on page 9-16
After resetting the MCU a delay may occur when synchronizing with the external NTP server.
Three assembly variations, MPMx-S, MPMx-D and MPMx-Q, differing in resource capacity, are 
available for the RealPresence Collaboration Server (RMX) 1500.
