MailBag Friday (#28)

Every Friday, we dedicate this space to sharing solutions for some of the most frequently asked questions posed to our ThinManager Technical Support team.  This weekly feature will help educate ThinManager Platform users and provide them with answers to questions they may have about licenses, installation, integration, deployment, upgrades, maintenance, and daily operation.  Great technical support is an essential part of the ThinManager Platform, and we are constantly striving to make your environment as productive and efficient as possible.


I have installed the ACP ThinManager on my laptop and the application on the iPad to use your iTMC function.  I need to know about the network configurations, how should they be set up? Currently, I am not able to connect to the server from the iPad. Both devices are connected on the same wireless network. Any ideas?


You will need to download and install the iOS Proxy Program for ThinManager:

Additionally, our wiki ( would be a great tool for you to use in setting up ThinManager and iTMC.



I currently have 5 sessions of ThinManager & InTouch per device in our control room and three  floating concurrent InTouch sessions for engineers to use on an ad hoc basis.  Can we use ThinManager to control auto disconnect of an unused session and ultimately relinquish the concurrent InTouch license if the user fails to log out or disconnect?  We would need to determine the device the session is coming from so that we do not auto disconnect the control room operators after a period of inactivity.


You can accomplish your goal by turning off “Always maintain a connection” from the Display Client.

Establishing an Inactivity Timer within Windows:(in 2008 R2): Start > Administrative Tools > Remote Desktop Session Host Configuration > RDP-Tcp > Sessions  (

This can also be established via GPO if it needs to be on a per user basis rather than a global setting (



We want to incorporate Digital Persona fingerprint readers for our engineers to log into our HMI system.  We are using Arista 240 Box PCs. Is this something that can be done?


Presently ThinManager only supports the below RF-ID Readers:

Product ID


Package Requirements



Serial Package 5 or 6 HID/HID2


Universal Serial Bus (USB) Package 5 or 6 HID/HID2


Universal Serial Bus (USB) Package 6 HID/HID2


Please see the RF-ID Readers “ThinManager Knowledge Base” page for more information:




Is it possible to use 3 USB/VGA dongles on an Arista TK-3770 (or dual monitor Arista commercial unit)?  We have one of these boxes and would like to run 4 screens via your MultiMonitor function.


In our test lab, we have 4 monitors on a TK-3550 so the TK-3770 would work as well.  Keep in mind that there could be top line performance issues depending on how graphic intensive your sessions are because the USB/VGA Dongles are taking processing power/resources from the Arista box, and the HMIs would potentially have a lot of changing graphics that need to be redrawn.
