Example:
1. The user’s module production batch is 3202996, 3202996≥3202995, and the module with production batch
3202996 is an active crystal oscillator module;
2. The user’s module production batch is 3202994, 3202994 < 3202995, and the module with production batch
3202994 is a passive crystal oscillator module.
The E77-900M22S module includes an active crystal oscillator version and a passive crystal oscillator version.
Users can distinguish them according to the production batch number of the module SN code. The production batch
number ≥3202996 is the active crystal oscillator version module (user-customized passive Except for the crystal
oscillator version), the rest are passive crystal oscillator versions.
SN code description: S3202996S00001, 3202996 is the production batch, and 00001 is the production serial number.
Example:
1. The user’s module production batch is 3202997, 3202997≥3202996, and the module with production batch
3202997 is an active crystal oscillator module;
2. The user’s module production batch is 3202995, 3202995 < 3202996, and the module with production batch
3202995 is a passive crystal oscillator module.
