Caveat for allowing two or more Device Adapter UNIStim endpoints to register

Prolog information
Setting the Max. Simultaneous Devices value to 1 allows a user using any UNIStim station to register by using a 2050 soft client, without requiring additional licenses. This configuration is also a practical option if a user wants to use a UNIStim endpoint for emergency purposes, and the other available stations have fewer feature buttons.
You can allow any UNIStim endpoint type to share a single user definition. If you use a less capable endpoint (with fewer feature buttons) that has a simple definition as your primary station for Sequential Registration, and then register a more capable endpoint (with more buttons), then:
  • All feature function buttons that are configured on the primary station are available on the more capable station.
  • Additional buttons on the more capable station are undefined and cannot be used.
For example, a user wants to use a 1120 and a 1140 endpoint sharing the same station definition and user profile.
The station definition for a 1120 endpoint has eight programmable buttons, which are 0 through 7. These buttons include the four physical buttons (0 through 3) on page 1, and four buttons (4 through 7) on page 2, which are obtained by using the Shift key. There are no additional buttons on the Feature Buttons tab.
The station definition for a 1140 endpoint allows up to 12 programmable buttons, plus one or more expansion modules. In addition to the eight buttons (0 through 7) on the base button page, there are four additional buttons on the Feature Buttons tab.
If you set the 1120 station definition as the primary definition, the 1140 endpoint can log in to the 1120 station definition and access buttons 0 through 7. This allows all feature functions of the 1120 on the 1140, but the four additional feature buttons on the 1140 are lost. 
Conversely, if you set the 1140 station definition as the primary definition, and when the user registers on the 1120 by using the station definition of the 1140, then buttons 8 through 11 and any expansion modules on the 1140 are lost. Only the eight lowest numbered buttons are available. The lost buttons and expansion modules may contain feature functions, which are also lost.
