DS9097E Übersicht
An RS-232C COM-port adapter is an interface accessory that bridges the voltage-domain mismatch between a legacy computer serial port and a 1-Wire-compatible iButton probe. It sits between the host computer and probe, translating bidirectional data and control signals while leaving protocol handling and device programming to the connected host software.
The DS9097E is the upgraded counterpart to the DS9097. Its defining feature is the 12 V programming capability for DS198x Add-Only iButtons. It retains support for reading and writing SRAM and EEPROM devices in the listed DS199x, DS196x, and DS197x families. This combination makes it useful for mixed legacy data-logger and access-control workflows.
The device uses RS-232C levels of plus or minus 12 V for level conversion. Its operation and wiring center on the computer-side TXD, RXD, DTR, RTS, and PC-ground connections described in the manufacturer datasheet. A 12 V auxiliary supply is identified as necessary for certain programming arrangements, but the verified excerpt does not provide a complete nominal package or connector specification.
Typical uses include reading and programming iButton devices attached to an iButton probe, supporting DS198x Add-Only programming, and maintaining legacy computer-to-probe communication. Engineers should verify connector pin assignments, probe requirements, host software support, and the auxiliary-supply arrangement against the manufacturer datasheet before assembly or replacement.
Because the DS9097E is a passive interface adapter rather than a powered logic IC, it has no typical quiescent-current or switching-converter specification. Selection should focus on supported device families, RS-232 voltage compatibility, 12 V programming behavior, connector assignment, and whether existing hardware can be reused without modification.
This page consolidates the verified Analog Devices product description, datasheet links, programming capability, supported iButton families, and RS-232 interface details. Missing electrical, dimensional, connector, lifecycle, and commercial values are explicitly marked as data needed rather than inferred.

Typische Anwendungen
DS9097E ist geeignet für 6 Anwendungs: DS198x Add-Only iButton Programming, Legacy RS-232 iButton Service Port, DS199x Read and Write Utility, DS196x and DS197x Data-Logger Access, Mixed iButton Device Fleet Maintenance, Access-Control Device Maintenance.
DS198x Add-Only iButton Programming
The DS9097E is specifically suited to programming EPROM-based DS198x Add-Only iButtons because the verified Analog Devices description states that the upgraded adapter supplies the required 12 V. Install it between a legacy RS-232C COM port and a compatible iButton probe, preserving the documented TXD, RXD, DTR, RTS, and PC-ground assignments. The key benefit is dedicated DS198x programming capability rather than ordinary read/write operation alone. Before deployment, verify probe compatibility, the required 12 V auxiliary-supply arrangement, and host software support. This evidence does not establish programming time, write endurance, or performance for an individual iButton.
Empfohlen
Legacy RS-232 iButton Service Port
The DS9097E provides a direct interface from a legacy RS-232C COM port to an iButton probe. Its passive signal paths perform +/-12 V level conversion and rely on the RS-232 interface for operating power, avoiding a separate powered interface in normal operation. The documented DB-25 assignment uses TXD on pin 2, RXD on pin 3, DTR on pin 20, RTS on pin 4, and PC-ground on pin 7. This makes it useful when maintaining older data-acquisition or access-control equipment. Confirm connector orientation and software support because legacy COM-port equipment may use nonstandard serial implementations.
Empfohlen
DS199x Read and Write Utility
The DS9097E can connect compatible DS199x devices for reading and writing through an iButton probe and an RS-232C host interface. Because it also includes the DS198x 12 V programming upgrade, it is more broadly useful for mixed service fleets than a plain read/write-only workflow. The adapter handles physical level conversion, while command exchange and device authentication remain responsibilities of the host and probe. Validate the exact DS199x model, memory type, and application protocol before use. The verified data confirms family-level support but does not provide throughput, timing, or environmental ratings.
Empfohlen
DS196x and DS197x Data-Logger Access
DS9097E supports reading and writing SRAM and EEPROM-based DS196x and DS197x devices according to the verified manufacturer description. It is therefore applicable to service workflows involving compatible iButton data loggers accessed through an iButton probe. The RS-232C adapter translates host-side levels of +/-12 V, and its documented control pins support the legacy communication path. Because device capabilities can vary within each family, engineers should confirm the exact logger model and command set in the manufacturer documentation. The adapter does not itself specify transfer speed or memory capacity.

Mixed iButton Device Fleet Maintenance
A mixed service environment containing DS198x Add-Only, DS199x, DS196x, and DS197x products benefits from the DS9097E’s combined programming and read/write coverage. The adapter can support the DS198x family through its verified 12 V capability and handle compatible SRAM and EEPROM devices through the same RS-232 probe interface. This consolidates service procedures and reduces adapter changes compared with a setup limited to the original DS9097. The claim applies only to the device families named by Analog Devices. Exact security, write-cycle, and environmental requirements must be evaluated at the individual-device and system level.
Empfohlen
Access-Control Device Maintenance
DS9097E is applicable when a maintenance workstation uses a legacy RS-232C connection to service compatible iButton access devices. Its passive +/-12 V level conversion connects the computer interface to an iButton probe, while the E version adds 12 V programming support for DS198x Add-Only products. System integrators should verify the access-control software’s supported device list, probe wiring, and security procedures before granting tool access. The verified material does not establish compliance for access-control or security systems, so this application should be treated as a hardware-interface use case rather than a certified security solution.

Designhinweise
Do not substitute the DS9097E for the DS9097 solely because both are passive RS-232 adapters. Analog Devices identifies DS9097E as the upgraded version capable of supplying the 12 V necessary for DS198x Add-Only programming. Confirm that the service target actually requires DS198x programming, then preserve the verified DB-25 assignments: TXD pin 2, RXD pin 3, DTR pin 20, RTS pin 4, and PC-ground pin 7.
The verified excerpt says the adapter is powered from the RS-232 interface, but it also describes a regulated 12 V auxiliary supply at 10 mA minimum for certain programming arrangements. Treat these statements as distinct interface-power and programming-supply requirements. Use the complete manufacturer schematic to determine whether the auxiliary supply is mandatory for the selected DS198x device and probe; do not assume host COM-port power can source every programming condition.
Legacy COM-port adapters are sensitive to connector orientation and signal naming. Verify the male or female DB-25 configuration, cable orientation, and probe mating connector before energizing or programming. The supplied evidence lists pin numbers but does not establish connector gender or mechanical drawing. Also verify that TXD-to-RXD routing is appropriate for the cable and host software so data and handshake signals are not reversed.
Compliance-Informationen
The verified excerpts do not provide RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 declarations. AEC-Q100 is recorded as not applicable because DS9097E is described as a passive adapter accessory rather than an automotive semiconductor; this does not imply any other compliance.
