E200E299

E200E299 is a designation used in some embedded and networked devices to refer to a contiguous range of error codes within an E-series taxonomy. The range E200 through E299 is commonly reserved for faults related to peripheral interfaces, sensor subsystems, and certain hardware-level communications, though the exact meanings are device-specific and not standardized across manufacturers.

Code format and interpretation: In most implementations, error codes in this range are displayed as an “E” prefix followed by three digits (for example, E201, E214). They are often accompanied by a short textual description, and may include an error severity level and recommended remediation steps. The mapping from code to description is typically documented in the device’s diagnostic manual; in some systems, the codes are hierarchical, with the hundreds digit indicating the subsystem family (2xx for sensors/IO, 3xx for power, etc.).

Examples and conventions: Some common but illustrative examples include E201 indicating a sensor read error, E210 indicating a timeout communicating with a peripheral, and E230 indicating a calibration out-of-range condition. It is important to note that the exact definitions vary by product and vendor.

Diagnostics and remediation: When a code in the E200–E299 range is reported, users typically review the event log, perform a repeatable test to confirm the error, check connections and power, update firmware if available, and follow vendor guidance. If the issue persists, escalation to technical support is common.

Relation to broader error-code systems: The E200–E299 range is analogous to other vendor-specific code families and should not be treated as a universal standard. It differs from standardized diagnostic codes such as automotive OBD or operating-system error classes.
