Description and Specifications

The XPort embedded device server is a complete network-enabling solution enclosed within an RJ45 package. This miniature serial-to-Ethernet converter empowers original equipment manufacturers (OEMs) to go to market quickly and easily with networking and web page serving capabilities built into their products.

The XPort

The XPort contains Lantronix’s own DSTni controller, with 256 Kbytes of SRAM, 16 Kbytes of boot ROM, and integrated AMD 10/100 PHY.
The XPort also contains the following:

• 3.3-volt serial interface
•  All I/O pins are 5V tolerant
•  4-Mbit flash memory
•  Ethernet magnetics
•  Power supply filters
• Reset circuit
•  +1.8V regulator
•  25-MHz crystal and Ethernet LEDs

The XPort requires +3.3-volt power and is designed to operate in an extended temperature range (see technical data).

XPort Block Diagram
The following drawing is a block diagram of the XPort showing the relationships of the components.

PCB Interface

The XPort has a serial port compatible with data rates up to 920 kbps (in highperformance mode). The serial signals (pins 4–8) are 3.3V CMOS logic level, and 5V tolerant. The serial interface pins include +3.3V, ground, and reset. The serial signals usually connect to an internal device, such as a UART. For applications requiring an external cable running with RS-232 or RS-422 4-wire and RS-485 2-wire voltage levels, the XPort must interface to a serial transceiver chip.

| 3| External reset in
Data Out| 4| Serial data out (driven by DSTni’s built-in UART)
Data In| 5| Serial data in (read by DSTni’s built-in UART)
Signal Name| XPort Pin #| Primary Function
---|---|---
CP1/RTS (Configurable Pin 1)| 6| CP1 can be configured as follows:

• Flow control : RTS (Request to Send) output driven by DSTni’s built-in UART for connection to CTS of attached device.
• Programmable input/output : CP1 can be driven or read through software control, independent of serial port activity.

CP2/DTR (Configurable Pin 2)| 7| CP2 can be configured as follows:

• Modem control : DTR (Data Terminal Ready) output driven by DSTni’s built-in UART for connection to DCD of attached device.
• Programmable input/output : CP2 can be driven or read through software control, independent of serial port activity.

CP3/CTS/DCD (Configurable Pin 3)| 8| CP3 can be configured as follows:
• Flow control: CTS (Clear to Send) input read by DSTni’s built-in UART for connection to RTS of attached device.
• Modem control: DCD (Data Carrier Detect) input read by DSTni’s built-in UART for connection to DTR of attached device.
• Programmable input/output: CP3 can be driven or read through software control, independent of serial port activity.

Ethernet Interface
The Ethernet interface magnetics, RJ45 connector, and Ethernet status LEDs are all in the device server shell.
Table 2-2 Ethernet Interface Signals (Industry Standards)

LEDs
The XPort contains the following LEDs:

• Link (bi-color, left LED)
• Activity (bi-color, right LED)

Table 2-3 XPort LED Functions

Dimensions

The XPort dimensions are shown in the following drawings.

Recommended PCB Layout

The hole pattern and mounting dimensions for the XPort device server are shown in the following drawing. For proper heat dissipation, it is recommended that the PCB have approximately 1 square inch of copper attached to the shield tabs. The shield tabs are an important source of heat sinking for the device.
The XPort shield is considered “chassis ground” and should be separate from “signal ground”. ESD near the XPort at the panel opening will likely jump to the shield.
We recommend using high voltage (~200V), low ESR, 0.01uF capacitors to connect chassis ground to both signal ground and 3.3V. This will cause any voltage spike from ESD to be imparted equally to both signal ground and 3.3V with no net voltage increase between 3.3V and signal ground. For the highest level of ESD protection of the XPort, it  is recommended that the shield not be directly connected to signal GND. The metalshield fingers around the XPort’s RJ45 should physically contact the product housing when the housing is metal, or metallic coated.
The shield is also a heat sink for the internal EX Processor. As in all heat sinking applications, the more copper connected to the heat sink the better. Adding 1 inch square inch of copper flood on the PCB is adequate to allow the XPort to work up to +85°C. If the application does not expect to see temperatures up to +85°C the heat sink may be smaller than 1 square inch.

Soldering Recommendations

CAUTION: Do not wash the XPort module.
This is an electrostatic sensitive device. Do not open packaging and handle these devices except at a static-free workstation.
This section provides guidance in developing a manufacturing assembly process for the XPort embedded device server.
The following table summarizes compatibility to manufacturing soldering and washing processes and the profile details are described below the table.

Reflow Soldering [Profile]| Wave Soldering [Profile]| Hand Soldering [Profile]| Washing
---|---|---|---
Not compatible1| Compatible [WS-A]| Compatible [HS-A]| Not Compatible2

[WS-A] Wave Soldering Compatible – Recommended Profile

•  T1-T2: Flux activating temperature range(According to data sheet of Flux)
• t1:  Flux activating time 30-60 seconds between T1 to T2.
• t2:  Time of Leads immersed in solder (3-6 seconds)

Note: Profile is temperature at soldered pins.
[HS-A] Hand Soldering Compatible – Recommended Profile 60-watt soldering iron with tip temperature at 380°C +/- 30°C, a maximum duration of 10 seconds.

1. Exposing product to reflow process can deform plastic material causing interference with RJ45 pin movement & insertion of Ethernet plug into jack. Do not use in reflow ovens, or process using paste-in-hole reflow.
2. Washing is a process to remove manufacturing process contaminants, typically after soldering. Washing enclosed products can force outside contaminants to become trapped inside product and affect product function.

Product Information Label

The product information label contains important information about your specific unit, such as its product ID (name), bar code, part number, and Ethernet (MAC) address.

Note: The Part Number and MAC Address on the product label will vary according the unit model (XPort-03, XPort-04 or XPort-05).

Electrical Specifications
CAUTION: Stressing the device above the rating listed in Table 2-4 may cause permanent damage to the XPort. Exposure to Absolute Maximum  Rating conditions for extended periods may affect the XPort’s reliability.
