BASIC OPERATION

Powering Up the Design Kit

• Connect PCB 3.3V and GND banana plugs to power supply. A 2A supply is recommended. At steady-state, the

system should draw approximately 700mA.

• Verify that jumpers are configured as described in Table 2

General

• Upon power-up, the DS33R11 Queue overflow LED (DS02 red) will not be lit; also, the INT LED (DS01 red) will

not be lit. PHY LINK LED (DS07 green) should be lit if the Ethernet is connected. Transceiver RLOS LED

(DS05 red) will be lit.

• DS33ZH11 does not have Queue overflow or INT pins. DS21348 and DS3150 RLOS LEDs (DS15 and DS13

red) will be lit.

Following are several basic system initializations.

Basic DS33R11 Initialization

This section covers two basic methods for configuring the DS33R11.

1. Device-Driver Based Configuration. If the pins J09.4+J09.6 are jumpered, the device driver autoconfigures

the DS33R11 upon power-up. This enables traffic to pass from the Ethernet port to the serial port. Consult

the device driver documentation for further details.

2. Register-Based Configuration. Launch ChipView.exe and select Register View. When prompted for a

definition file, pick the file named DS33Z11.def. Three definition files will load: DS33Z11 control, DS33Z11

port, and DS2155 transceiver. Go to the File menu and select F

ile→Memory Config File→Load .MFG file.

When prompted, select the file named basic_config.mfg. Following this, load the file

e1_gapclk_crc4_hdb3_nocas.ini using the menu selection F

ile→Initalization Config File→Load .INI file.

Additional Configuration for DS33R11

• Using a patch cable, connect the Ethernet connector to an ordinary PC, or network test equipment. This should

cause the link LED to turn on.

• Place a loopback connector at the T1E1 network side; RLOS LED DS05 should go out.

• At this point any packets sent to the DS33R11 are echoed back. Incoming packets (i.e., ping) should cause the

RX LED to blink, after which the TX LED should also blink.
