Hardware Configuration Using the DK101 processor board: · Connect the daughter card to the DK101 processor board. · Supply 3.3V to the banana-plug receptacles marked GND and VCC_3.3V. (The external 5V connector and the TIM 5V supply headers are unused.) · All processor board DIP switch settings should be in the ON position with exception for the flash programming switch, which should be OFF. · From the Programs menu launch the host application named ChipView.exe. Run the ChipView application. If the default installation options were used, click the Start button on the Windows toolbar and select Programs®ChipView®ChipView. Using the DK2000 processor board: · Connect the daughter card to the DK2000 processor board. · Connect J1 to the power supply that is delivered with the kit. Alternately, a PC power supply can be connected to connector J2. · From the Programs menu launch the host application named ChipView.exe. Run the ChipView application. If the default installation options were used, click the Start button on the Windows toolbar and select Programs®ChipView®ChipView. General: · Upon power-up the RLOS LED is lit, as well as the MCLK-2.048MHz and TCLK-2.048MHz LEDs. · Due to the dual winding transformer, only the 120W line build-out configuration setting is needed to cover 75W E1 and 120W E1. Quick Setup (Demo Mode) · · · The PC loads the program, offering a choice among Demo Mode, Register View, and Terminal Mode. Select Demo Mode. The program requests a configuration file, then select between the displayed files. (DS2155_E1_DSNCOM_DRVR.cfg or DS2155_T1_DSNCOM_DRVR.cfg). The Demo Mode screen appears. Upon external loopback, the LOS and OOF indicators extinguish. Quick Setup (Register View) · · · · The PC loads the program, offering a choice among Demo Mode, Register View, and Terminal Mode. Select Register View. The program requests a definition file, then select DS2155.def. The Register View screen appears, showing the register names, acronyms, and values. Predefined register settings for several functions are available as initialization files. ¾ INI files are loaded by selecting the menu File®Reg Ini File®Load Ini File. ¾ Load the INI file DS2155_T1_BERT_ESF.ini. ¾ After loading the INI file the following may be observed: The RLOS LED extinguishes upon external loopback. The DS2155/DS2156 begins transmitting a Daly pattern. When external loopback is applied, the BERT bit-count registers BBC1–3 and BEC1–3 may be updated by clearing and setting BC1.LC and clicking the Read All button. Miscellaneous: · Clock frequencies and certain pin bias levels are provided by a register-mapped CPLD, which is on the DS2155/DS2156 daughter card. · The definition file for this CPLD is named DS215x_35x_CPLD_V2.def. See the CPLD Register Map section for definitions. · All files referenced above are available for download at www.maxim-ic.com/DS2155DK. 4 of 21 DS2155DK/DS2156DK T1/E1/J1 Single-Chip Transceiver Design Kit Daughter Cards Sample UTOPIA II Configuration (DS2156 Only) The following register settings configure the DS2156 daughter card for UTOPIA II, single CLAV, 8-bit mode on PHY port 0. UTOPIA II bus connection is provided by header J1 (Tx) and header J2 (Rx). After configuring the following registers toggle the MSTREG.URST bit to reset the UTOPIA II core.

Table 1. Daughter Card Address Map OFFSET 0X0000 to 0X0015 DEVICE DESCRIPTION CPLD Board identification and clock/signal routing 0X1000 to 0X10ff Single-Chip Transceiver Board is populated with one of the following: DS2156, DS2155, DS21352, or DS21354. Please see data sheet for details. Registers in the CPLD can be easily modified using the ChipView.exe, a host-based user interface software along with the definition file named DS215x_35x_CPLD_V2.def. Definition files for the SCT are named DS2155.def, DS21352.def, or DS21354.def, depending on the board population option. 5 of 21 DS2155DK/DS2156DK T1/E1/J1 Single-Chip Transceiver Design Kit Daughter Cards CPLD Register Map Table 2.
