(i)
(ii)
delivered hardware or software
non-observance of instructions contained in this manual and in any other documentation provided to user, or
(iii) misuse, abuse, use under abnormal conditions, or alteration by anyone other than IDT.
TO THE EXTENT PERMITTED BY LAW, IDT HEREBY EXPRESSLY DISCLAIMS AND USER EXPRESSLY WAIVES ANY AND ALL WARRANTIES, WHETHER
EXPRESS, IMPLIED, OR STATUTORY, INCLUDING, WITHOUT LIMITATION, IMPLIED WARRANTIES OF MERCHANTABILITY AND OF FITNESS FOR A
PARTICULAR PURPOSE, STATUTORY WARRANTY OF NON-INFRINGEMENT, AND ANY OTHER WARRANTY THAT MAY ARISE BY REASON OF USAGE
OF TRADE, CUSTOM, OR COURSE OF DEALING.
Restrictions in Use
IDT’s Mass Calibration System (MCS), consisting of the Communication Board (SSC CB), Mass Calibration Board (MCB), and the
ZSSCxxxx Evaluation Software,
is designed for sensor module evaluation, laboratory setup and the module’s mass calibration development only.
IDT’s Mass Calibration System (MCS) must not be used for module production and production test setups.
Firmware Compatibility
The current version of the SSC CB is V4.1. For previous SSC CB versions, if the firmware version is earlier than V2.19a, the board will not be able to communicate
with the SSC Mass Calibration Board V2.1. In this case, it is necessary update the firmware, which can be downloaded from
www.IDT.com/SSC-MCB.
For details
about the update procedure, refer to the
SSC Communication Board Application Note – Firmware Updates
available at
www.idt.com/ssc-cb.
Compatibility with Previous MCB Versions
If the MCB V2.1 is to be used with a previous version MCB V2.0, refer to the
ZSC31xxx/ZSSC3xxx MCS Application Note – Mass Calibration Board Interaction
(available upon request). Do not connect a previous version MCB V2.0 as the first MCB connected to the SSC CB.
