1: Introduction About the Integration Guide This guide provides the information needed to integrate the MatchPort b/g Pro™ device server within another product. The intended audiences are the engineers responsible for integrating the MatchPort b/g Pro into their product. Additional Documentation The following guides are available on the product CD and the Lantronix Web site (www.lantronix.
2: Description and Specifications The MatchPort b/g Pro embedded device server is a complete network-enabling solution on a 1.75"x1.75" PCB. This miniature device server empowers original equipment manufacturers (OEMs) to go to market quickly and easily with networking and web page serving capabilities built into their products. The MatchPort b/g Pro has the following features: Power Supply: Single regulated 3.3V input required. On board step down conversion.
2: Description and Specifications Figure 2-1.
2: Description and Specifications MatchPort b/g Pro Pinouts There are two headers of 1x20, 2-mm pin spacing. The odd row header is designated as P1; pins are numbered 1 to 39. The even row header is designated as P2; pins are numbered 2 to 40. PIN # NAME Dir Active level FUNCTION P1.1 P1.3 P1.5 P1.7 P1.9 P1.11 P1.13 P1.15 P1.17 P1.19 P1.21 P1.23 P1.25 P1.27 P1.29 P1.31 P1.33 P1.35 P1.37 P1.39 RESETIN# RSTTODFLT TX1 RTS1 RX1 CTS1 CP1 CP2 CP3 CP4 TX2 RTS2 RX2 CTS2 CP5 CP6 CP7 RSVD S3.
2: Description and Specifications Note: To minimize noises as well as voltage drops at the connection, We recommend direct connection of 3.3V and ground on the MatchPort b/g Pro to 3.3V power and ground planes of the target board in place of heavy trace routing. Reset The MatchPort b/g Pro reset pin RESETIN# is an input-only pin and connects to an 811type reset IC. This input is for a pushbutton switch type manual reset. If no external reset control is desired, leave this pin floating.
2: Description and Specifications Ethernet LED Connections The E_LINKLED and E_ACTLED signals are driven by the PHY. They are active low. Recommended connections on the target board are shown below. Figure 2-3. Recommended LED Connections Warning: The MatchPort b/g Pro has two 4.7K pull-ups on the E_LINKLED and E_ACTLED signals to set up the PHY’s LED Indicator Mode as Ethernet Link and Activities at Power On Reset (POR).
2: Description and Specifications Figure 2-5. Reverse-SMA to U.FL (P/N 500-180-R) Figure 2-6. U.FL to U.FL Cable (P/N 500-181-R) Note: The antenna cable is included in the MatchPort b/g Pro sample. For production, it can be purchased from Lantronix or a cable supplier. Figure 2-7. R-SMA Antenna Connector Dimensions (not to scale) Antenna The MatchPort b/g Pro has been FCC certified with a 5-dBi gain antenna for wireless 802.11b/g. It is for applications with antennas of equal gain or less.
2: Description and Specifications Serial Input/Output The unit has two RS232 compatible serial ports supporting data rates up to 230 Kbps. They include dedicated RTS and CTS hardware flow control signals. Configurable Pins can be configured to function as DTR and/or DCD. Serial Port 1 can also be configured for RS422/485. RTS is used as TX enable. Configurable Pins can be configured to function as RS232/RS485 driver selection control and/or half/full duplex driver selection.
2: Description and Specifications Figure 2-9.
2: Description and Specifications Figure 2-10. Separate RS422 Transceivers for 2-Wire and 4-Wire Setups To protect the MatchPort b/g Pro and circuitry on the target board against ESD at serial ports, the selected transceiver(s) should have RS232/422/485 bus-pin ESD protection (typically around 15 KV) either on-chip or by external diode arrays. IO Configurable Pins (CPs) There are up to seven CPs if no DTR or DCD is used on the serial ports. All CPs have internal pull-up resistors, but the value differs.
2: Description and Specifications BOOTP_EN# The BOOTP_EN# pin performs two functions simultaneously. It drives an optional external diagnostics LED to indicate the status of the bootloader. It also serves as input to enable booting from the network when no valid FW image is found in FLASH. BOOTP enable Holding BOOTP_EN# low (via switch or jumper) during and up to 10 seconds after a reset allows booting the device with a FW image on a TFTP server only in case no valid image is present on FLASH.
2: Description and Specifications Figure 2-11. BOOTP_EN# APPLICATION CIRCUIT Electrical Specifications Caution: Stressing the device above the rating listed in this table may cause permanent damage to the MatchPort b/g Pro. Exposure to Absolute Maximum Rating conditions for extended periods may affect the MatchPort b/g Pro's reliability. Table 2-3.
2: Description and Specifications Parameter Symbol E_LINKLED, E_ACTLED Current Drive (sink) W_LINKLED IELED Min Typical 12 10 Max Units mA (see note below) mA Notes: Do not connect a pull-down resistor on E_LINKLED and E_ACTLED. All pins are not 5V-tolerant. Wireless Specifications Refer to the following table for the MatchPort b/g Pro’s wireless specifications: Table 2-5.

2: Description and Specifications Recommended PCB Layout The hole pattern and mounting dimensions for the MatchPort b/g Pro device server are shown in the following drawing: Figure 2-15. PCB Layout (Top View) Note: If a socket is used for product development purpose only, two 2-mm, 20-pin sockets spaced 1.42" apart can be used (e.g., Samtec P/N SMM-120-02-S-S-TR).
2: Description and Specifications 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 MAC address. Figure 2-16.
3: Demonstration Kit Using a MatchPort b/g Pro sample and the MatchPort Demonstration Kit, you can get familiar with the product and understand how to integrate the MatchPort b/g Pro into a given product design. Contents of the Kit The MatchPort Demonstration Kit contains the following items: MatchPort Demo Board 3.3V wall adaptor RS-232 cable, DB9F/F, null modem RJ45 Ethernet cable Antenna 2.15 dBi gain You must obtain a MatchPort b/g Pro sample separately for use with this Demonstration Kit.
3: Demonstration Kit Serial Interfaces The demo board has RS-232/422/485 transceivers, one per port. However, note that only Serial Port 1 supports RS232/RS422/485 on MatchPort b/g Pro. The table below lists the RS232 signals and corresponding pins on the demo board. All signals are level-shifted by the transceivers. Table 3-1.

Jumper 15-16, CP6 receives DCD from RS232 transceiver. Note: CP allocation in the tables above is the most straightforward for this specific board. However any CP can be assigned to any function. To reflect actual CP use in the eventual product (in case different), jumpers can be replaced with short wires to allow interchanging of connections. Table 3-7.
