Power and Ground

The MatchPort AR requires a regulated 3.3Vdc +/- 5% power input at P1.37 and
ground at pin P1.39.

Direct connection of 3.3V and ground on MatchPort AR to 3.3V power and ground
planes of the target board is recommended in place of heavy trace routing to
minimize noises as well as voltage drops at the connection.

Reset

The MatchPort AR 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.

MatchPort AR™ Integration Guide 9

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 AR provides Ethernet interface transmit ETX and receive data ERX
connections from a PHY device. Thus, before presenting signals to the outside world
using an RJ45 jack, a 1:1 Ethernet Magnetics is needed to interface and to isolate
the unit. A recommended connection diagram to an RJ45 jack with integrated 1:1
Ethernet magnetics is shown below.

2:Description and Specifications

Figure 2-3. 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.

MatchPort AR™ Integration Guide 10

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 2-4. Recommended LED Connections

Warning: The MatchPort AR 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.

2:Description and Specifications

Serial Input/Output

The unit has two serial ports compatible with RS232 serial standards at data rates
up to 230 Kbps. Serial Port 1 can also be configured as RS422/485, but Serial Port 2
cannot. The serial I/O signals are 3.3V CMOS logic level. Serial signals can be
connected to the OEM CPU/UART or RS232/422/485 serial transceivers. For
evaluation and prototype work, it is convenient to have an external RS232 interface
that can connect to the serial port on a PC. The MatchPort Demo Board has
RS232/422/485 transceivers to implement this external interface. If desired, use the
CPs to create a DTE or DCE-style interface using any available CPs. To create these
interfaces, connect the signals according to the tables below.

Note: CPx and CPy are any of the available CPs.

Figure 2-7. Separate RS422 Transceivers for 2-Wire and 4-Wire Setups

To protect the MatchPort AR 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 using web
pages (see the User Guide). All CPs have a pull-up.

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.

The MatchPort AR will issue a BOOTP request to acquire an IP address for itself, the
IP address of a TFTP server, and the filename of the FW image on the TFTP server.
Then it will fetch that file via TFTP, verify, and execute it.

Diagnostics LED

After supplying power to the unit or pressing and releasing the reset button, the
diagnostics LED turns on and stays on while the bootloader is running and does not
encounter any errors. After the bootloader loads firmware from serial, network or
FLASH, it turns off the LED right before handing over execution.

In case an error occurs during the bootloader operation, it will flash the LED. The
pattern will be pause, X * long flashes, Y * short flashes, pause, X long flashes, etc.

2:Description and Specifications

X is the first digit of the error number and Y the second.

Following are the currently implemented errors:

INVALID_BOOTLOADER_CHECKSUM 11
NO_FLASH_IMAGE_FOUND 12
BAD_FLASH_IMAGE_FOUND 13
BAD_COMMAND_PARAMETER 14
NO_BOOTP_RESPONSE 15

RECEPTION_TIMEOUT 18
RECEPTION_OVERRUN 19
IMAGE_OVERSIZE 21
BAD_IMAGE_CHECKSUM 22
BAD_IMAGE_DESTINATION 23
INTERNAL_CODING_PROBLEM 24

Pin Connection Options

The circuit below is an example on how to correctly connect a switch (or permanent
jumper) and an LED to the BOOTP_EN# pin. The customer has the option of
implementing either the switch/resistor or the driver/LED or both or none.

The switch can be replaced by a jumper or hardwire. Having the hardwire in place
means that if the firmware image in FLASH becomes corrupt, the MatchPort AR will
automatically send out BOOTP requests over the network. This could be a security
risk. The switch or jumper allows BOOTP requests to be sent only after manual
intervention.

If no switch/jumper/hardwire is installed, network recovery is only possible by issuing
a!NL command over the serial port.

Figure 2-12. PCB Layout (Top View)

2:Description and Specifications

 To optimize noise and cross-talk reduction, noise immunity, and impedance

matching on ETX+, ETX-, ERX+, ERX-, follow these guidelines when routing
traces on the target PCB:

− Route (ETX+, ETX-) pair as close to each other as possible, and far

away from ERX+, ERX- and other signals

− Route (ERX+, ERX-) pair as close to each other as possible, and far

away from ETX+, ETX- and other signals

− Set up PCB routing properties on each pair (ETX+, ETX-) and (ERX+,

ERX-) to achieve 100-ohm impedance.

− For EMI purposes, connect the metal housing (shield) of the RJ45 jack to

Power Ground or Earth Ground and do not allow floating.
If power ground and earth ground are to be separated, add ceramic

capacitors in the range of 1000 pF to 0.1 uF in a stitching pattern
between the two grounds to provide low impedance paths at high
frequencies. The voltage rating on the ceramic capacitors should be
much higher than the required isolation voltage between the two
grounds.

 Connect 3.3V and ground on the MatchPort AR directly to 3.3V power and

ground planes of the target board in place of heavy trace routing. This will
minimize noises as well as voltage drops due to the trace.

 Make the 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.

jumpers re-routes signals on the demo board to drive LEDs (general purpose
outputs), to use as Serial control signals, or to connect to other places on target
board as General Purpose IO (GPIO).

In customers’ applications, any CP can be assigned as a function of DTR or
DCD. All CPs can be used as GPIOs.

If using CPs for any combination of the demo board configurations above, please use
the appropriate CP function selection as shown in Table 3-5. If assigning a CP for
any function other than the serial port, remove the jumper for the associated CP pin
from JP7 to avoid conflict with the serial port function.
