The DS9034PC PowerCap is a snap-on lithium power source for nonvolatile (NV) SRAMs in Dallas Semiconductor's directly surface-mountable PowerCap module base package. After a PowerCap module has been soldered in place and cleaned, the DS9034PC PowerCap is snapped onto the base to form a complete NV SRAM module. The PowerCap is keyed to prevent incorrect attachment and is designed to maintain mechanical and electrical contact with its host module base even during severe mechanical shock and vibration. The DS9034PC is easily removed by inserting a regular screwdriver into the detachment feature and prying gently outward and upward to release the PowerCap from the module base.

The DS9092iButton® probe provides the electrical contact necessary for the transfer of data to and from the DS19xx family ofiButtons. The round probe shape provides a self-aligning interface that readily matches the circular rim of theiButton's MicroCan package. Metal contacts resist wear and are easy to keep clean.The DS9092 is available with a flat faceplate (standard) or with optional tactile feedback. The center contact of the standard reader has no moving parts, making this a more rugged interface for harsh environments. This type of probe is best suited for designs where theiButton is brought into contact with the reader.The tactile feedback probe is ideal for situations where theiButton is stationary and the movable reader is brought in contact with it.Both types of probes are available in a panel-mount version. The tactile feedback probe is also available in a grip-mount version. The panel-mount probes are fastened behind the panel with a push-on type spring-nut.The two 15cm 22AWG wires are provided for easy connection to the system microcontroller. The handgrip mount probe comes attached to a 10cm handle and 1m cable which is terminated with an RJ-11 jack.

The DS9093F plastic snap-in fob offers the simplest way to mount aniButton® for applications that require only momentary contact. The fob can be attached to a key ring for carrying. Do not apply solvents or adhesives to this fob. This might affect the mechanical strength and reliability.The DS9093N angled fob is an alternate way to mount aniButton for applications that require only momentary contact. Due to the different mounting technique, the DS9093N can be used with the F5 MicroCan® only. TheiButton is inserted into this fob by press-fitting. For permanent mount, theiButton can be locked by a DS9093RA Lock Ring.The DS9093A is very similar to the DS9093N. It has about the same size as the DS9093N and can be used with the F5 MicroCan only. TheiButton is inserted by press-fitting the flange of the MicroCan into the cavity of the fob. In contrast to the DS9093N, no additional parts are needed for permanent mounting. The DS9093A is available in black, blue, green, red, and yellow.

The DS9094FiButton® PCB Clip holds aniButton and connects to a printed circuit board. By deflecting the spring clip in the molded housing, aniButton can be inserted and extracted without special tools. If reverse insertion is attempted, the beveled edge on the housing prevents contact.

The DS9097U is a sophisticated RS-232 to 1-Wire®adapter, which performs RS-232 level conversion and actively generates the 1-Wire communication signals. Together with an adequate software driver, it enables a Windows®-based PC to directly communicate with any 1-Wire device connected to the adapter's RJ11 port. The DB9 version reads and writes any non-EPROM 1-Wire device. To write to EPROM devices, the DB25 version with external power supply is required. For a list of suitable 1-Wire network cables, refer to theConnectivity Matrixtable in the DS1402x 1-Wire network cables data sheet.All DS9097U adapters are based on the DS2480B serial 1-Wire line driver chip. The RXD/TXD polarity select input of the DS2480B is connected to VDD(noninverting).Free software drivers can bedownloaded here.The DS9097U communicates with 1-Wire devices at standard speed as well as overdrive speed. The serial port must support a data transmission rate of 9600bps. Under software control, the adapter can be set up for RS-232 data rates of 19200bps, 57600bps, and 115200bps. The two higher rates are recommended for communication at overdrive speed with overdrive-capable devices. Since the DS9097U operates in a byte mode, every data byte received from the RS-232 port generates eight time slots on the 1-Wire line.Note that there are some COM ports that use signal levels of less than (±) 5V. The DB9 versions of this adapter do not work with such ports. The DS9097U-E25 adapter, however, functions in most cases if external power is supplied. Without EPROM programming, the external power can be anywhere in the range of 6V to 9V. For EPROM programming the voltage must be at 12V in any case. Before using an externally powered DS9097U-E25 with a COM port of less than (±) 5V, check whether the COM port will not be damaged by 5V on its RXD input.
