STU Installation
Choosing an STU
In addition to price considerations please bear in mind the following factors:
- If you want to use your signature pad over RDP then there are currently (April 2024) two options:
-
Purchase a separate USB forwarding tool to handle the pen data over the network connection)
-
Choose an STU which operates serially i.e. the 430V (this is no longer in production and will therefore probably be difficult to obtain) or 540 (which can be switched into serial mode if needed)
NOTE 1: The uploading of colour images over a serial connection to a colour STU is too slow to be user-friendly and for this reason the 540 allows for the pre-uploading of images into ROM for superior response times. This requires special handling in the application.

If you need to capture signatures over Citrix then please see our Citrix Compatibility list
- The 300, 430 and 430V provided limited screen space so if you need to display a lot of information for the user to read prior to signing then it would probably be better to choose a 540. The 300 and 430V have in fact been discontinued.
- The STU-541 is primarily aimed at installations where a high degree of security is required in the data transmission between the pad and the PC. The 541 uses TLS encryption to deliver this. In addition the STU-541 is no longer in production so may be difficult to obtain.
