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. Notes: u u The MatchPort b/g Pro Demo Kit provides hardware and firmware for customer evaluation.
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: u u u u u u u u u Power Supply: Regulated 3.3V input required. There are step-down converters to 1.8V and 1.
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 FUNCTION PIN # NAME FUNCTION P1.1 RESETIN# P2.2 GND Ground P1.3 P1.5 RSVD TX1 P2.4 P2.6 NC ETX+ P1.7 RTS1 P2.8 ETX- P1.9 RX1 P2.10 ETCT P1.11 CTS1 P2.12 ERCT P1.13 CP1 Active low Reset. Leave floating if not used. Reserved.
2:Description and Specifications There is an on board capacitor, 0.1uF to ground, at the RESETIN# to filter out transient voltages. However, as always, it is a good practice to have RESETIN# trace on the target board as short as possible to avoid reset occurrences when transient voltages such as those caused by ESD are present. Ethernet Connections The MatchPort b/g Pro provides Ethernet interface transmit ETX and receive data ERX connections from a PHY device.
2:Description and Specifications Figure 2-2. Connection Diagram to an RJ45 Jack We recommend a low capacitance TVS diode array such as a Semtech SRV05-4 at ETX+, ETX-, ERX+, ERX- if frequent transient voltages are present. 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.
2:Description and Specifications 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). Do not connect these two signals with any pull-down resistors as they may corrupt the logic level on these two signals at POR, causing undesired operation. Wireless LED Connections The W_LINKLED is driven by the Radio Module. It is active low.
2:Description and Specifications 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 2-6. R-SMA Antenna Connector Dimensions (not to scale) Antenna The MatchPort b/g Pro has been FCC certified with a 5dBi gain antenna for wireless 802.11b/g. It is for applications with antennas of equal gain or less. The following are two of the recommended antennas with 2.15dBi gain and a link to their vendor.

2:Description and Specifications Figure 2-8. Separate RS232/422 Transceivers Figure 2-9.
2:Description and Specifications 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. Any CP can be configured as DTR or DCD as described above. CPs can be configured (see the User Guide). All CPs have a pull-up.
