DS21Q55DK Quad T1/E1/J1 Transceiver Design Kit
General
?
?
Upon power-up, the RLOS LEDs (green) will not be lit, the INT LED (red) will not be lit, but the FPGA status
LED (green) will be lit.
When operating in E1 mode, slide SW1–SW4 such that the BNC shell is grounded (to the left, as shown in the
board floorplan). When operating in T1 mode, ensure that SW1–SW4 are slid to the right as shown in the
board floorplan.
Miscellaneous
?
?
?
Clock frequencies and certain pin bias levels are provided by a register-mapped FPGA, which is on the
DS21Q55 daughter card.
The definition file for this FPGA is named DS21Q55DC_FPGA.def. The definitions are located on page 7. A
drop-down menu on the top of the screen allows for switching between definition files.
All files referenced above are available for download as described in the section marked “BASIC OPERATION ”
Quick Setup (Demo Mode)
?
?
?
?
The PC will load ChipView offering a choice between DEMO MODE, REGISTER VIEW, and TERMINAL
MODE. Select Demo Mode.
The program will request a configuration file, select among the displayed files
(DS2155_E1_DSNCOM_DRVR.cfg or DS2155_T1_DSNCOM_DRVR.cfg).
The Demo Mode screen will appear. Upon external loopback, the LOS and OOF indicators will extinguish.
Note: Demo Mode interacts with the device driver, which is resident in the DK101/DK2000 firmware. The
current implementation of this driver is for one device. As such, the demo mode will only interact with Port 1 .
With minor changes, the device driver is extendible to N devices.
Quick Setup (Register View)
?
?
?
?
The PC will load ChipView offering a choice between DEMO MODE, REGISTER VIEW, and TERMINAL
MODE. Select Register View.
The program will request a definition file. Select DS21Q55DC_FPGA.def; through the ‘links’ section this will
also load DS21Q55DC.def.
The Register View Screen will appear, showing the register names, acronyms, and values for the DS21Q55
Predefined register settings for several functions are available as initialization files.
?
?
?
INI files are loaded by selecting the menu File → Reg Ini File → Load Ini File
Load the INI file DS21Q55_T1_BERT_ESF.ini
After loading the INI file, the following may be observed:
? The RLOS LEDs (green) light upon external loopback.
? All four ports of the DS2Q155 begin 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.
