UltimusPlus I–II Software Version History
| Date | Version | Updates | Affected Dispenser(s) | Download |
| 5/5/26 | 2.34 |
Added support for new hardware Resolved an issue where ethernet connection would not recover from the cable being disconnected and reconnected Fixed intermittent issue where switching programs via NX or I/O appeared successful, but continued to use old program parameters Fixed rounding issue for NX reads when using units other than psi or inH2O Resolved an issue where unit would stop dispensing with 1 shot remaining to run limit Improved consistency in dispense times between vacuum and non-vacuum pressures between dispenses |
UltimusPlus I–II |
v2.34 |
| 6/25/25 | 2.33 |
Updated kernel to support new hardware. Updated initialization thresholds to support future hardware. No update available, as no need for field updates. |
UltimusPlus I–II |
- |
| 5/30/25 | 2.32 |
Updated for improved manufacturing testing and support for potential upcoming sensor improvements. |
UltimusPlus I–II |
v2.32 |
| 4/3/25 | 2.31 |
Fixed the web and touch interface from occasionally failing to switch to a new program despite looking like it did. Fixed the controller occasionally not booting after power on (fully black screen, no blue lights blinking from the cracks in the back). |
UltimusPlus I–II |
v2.31 |
| 1/28/25 | 2.30 |
Improvements for greater repeatability, improved vacuum performance, and reduced noise (bullet valve chatter). Eliminated the acquisition of irrelevant information that could prematurely fill the data log. |
UltimusPlus I–II |
v2.30 |
| 9/17/24 | 2.26 |
New vacuum control for UltimusPlus II units that is quieter and more reliable. |
UltimusPlus I–II |
v2.26 |
| 4/12/24 | 2.25 |
Fixes error being logged to a log file that is being deleted on startup. This resulted in the same blinking cursor error after extended times between reboots. |
UltimusPlus I–II |
v2.25 |
| 11/18/22 | 2.24 |
Fixes warning that was filling a log file. Log file is rotated every boot, so prior to this update, as long as the unit is not on for more than 6 weeks across the last two boots no issues are encountered. With this update there will be no limit on time between boots. The additional delay introduced in 2.23 is removed by using an alternate compatibility solution. |
UltimusPlus I–II |
v2.24 |
| 11/18/22 | 2.23 |
Patch for compatibility with future hardware revision updates. Causes less than a second additional delay during startup. |
UltimusPlus I–II |
|
| 5/5/22 | 2.22 |
Allows passwords starting with zero to be validated. Prior to this update, setting a password with a leading zero would prevent the use of the screen lock. |
UltimusPlus I–II |
v2.22 |
| 10/25/21 | 2.21 |
Added the log header row to log as described in documentation Fixed that the log would record 100,001 entries rather than 100,000 |
UltimusPlus I–II |
v2.21 |
| 9/28/21 | 2.20 |
Fixed MultiShot issues with short delay times Fixed short delay times between shots Eliminated slight latency variation in steady mode Language indicator now shows current language rather than the current translation of English Fixed that ~ 1/1000 setting changes made would not be applied until the next change (or reboot) Network Configuration now allows full configuration of IPv4 address, mask, and gateway |
UltimusPlus I–II |
v2.20 |
| 10/27/20 | 2.19 | Updated IO allocation so the controller IO works more efficiently |
UltimusPlus I–II |
v2.19 |
| 7/31/20 | 2.18 |
Improved End-of-Cycle (EOC) feedback timing Added a reboot cycle in the case of bad sensor reads |
UltimusPlus I–II | v2.18 |
| Lowered operational pressure from 0.07 bar (1 psi) to 0.02 bar (0.3 psi) | UltimusPlus II | |||
| 4/29/20 | 2.17 | Updated the ATE test code and I/O allocation | UltimusPlus I–II | v2.17 |
| 4/9/20 | 2.16 | Updated vacuum stability by adding two control loops: One for the On/Off time of the valves and one to increase the sampling (done as error -> 0) | UltimusPlus I–II | |
| CAUTION: Software versions 2.14 and 2.15 are different for UltimusPlus I and UltimusPlus II. If your dispenser has software version 2.16 or later, do not downgrade the software to version 2.14 or 2.15. Doing so will adversely affect unit operation. | ||||
| 3/6/20 | 2.15 |
Updated the time period for MultiShot latency Updated the UI issue that occurred when the unit was in Teach mode and the displayed time would overrun Updated the time setting and test button lockouts in Steady mode |
UltimusPlus I UltimusPlus II |
|
| 2/27/20 | 2.14 |
Corrected the MultiShot time error and MultiShot interrupt Resolved an issue with missing shots Updated the Teach mode functionality Updated the pressure alarms and the sleep message Updated the ATE code for determining slope Updated the Log export Modified the overall vacuum settings Added new system password |
