Building the 6 Port E1.31 Bridge
The 6 Port E1.31 Bridge requires a fair bit of soldering so take your time and ensure you install the components in the correct orientation when required. Start by sorting the components by type and values. Look over the PCB before starting noting the location of the various components. Follow the standard procedure of installing the lowest profile parts first and ending up with the tallest.
Congratulations! That completes the construction of the 6 Port E1.31 Bridge!
Initial Testing
Programming the EEPROM
Current version of the firmware is v2.02 and you can download it here.
The Programming port on the Bridge is the 4 pin header near the WizNet adapter. Match up the silk screen labels with those on the Prop Plug. You will need to externally power the bridge when programming it.
- Download the Parallax Propeller Tool and install it.
- Run the Propeller Tool application and it will ask of you want to associate .eeprom files with the application, Say Yes.
- You can close the Propeller Tool application and double click on the .eeprom file you downloaded or from within the application go to File->Open and change the 'Files of type' to 'Propeller Applications' and open the Bridge_v2.02.eeprom file.
- A 'Object Info' screen will open, if not already enabled click 'Show Hex'
- Program the EEPROM on the Bridge by selecting 'Load EEPROM' and you are done.
Configuration Commands
Save
SAve n where n is a memory page number from 0 to 7. Writes the currently displayed configuration to the specified memory page
Load
LOad n where n is a memory page number, 0-7. Loads the specified memory page and displays the information on the web page.
Boot
BOot 999 will restart the system. Make sure you do a SAVE first if you have made any changes or your changes will be lost!
IP
IP a.b.c.d where a.b.c.d is any valid IP address
Subnet
SUbnet a.b.c.d or SUbnet n where a.b.c.d is any valid subnet mask value, or n is the size of the subnet in bits.
Gateway
GAteway a.b.c.d where a.b.c.d is any valid internet address. Usually the address of your router.
DNS
DNs a.b.c.d where a.b.c.d is any valid internet address. Usually the address of your router.
If you are only using DHCP (not recommended), you can leave the static IP areas unused.
Network addressing (static or DHCP IP) is only needed to access the configuration
page with a web browser. Once configured, no IP address is needed for normal operation.
The Default IP Mode, Web Server Mode, No Data Timeout, and Test Pattern commands affect
what happens when the system starts up.
Default
DEfault n where n is 0 or 1. DE 0 sets a default network mode of STATIC, DE 1 sets a default network mode of DHCP.
Universe
UNiverse b n Where b is the RJ45 output jack number, from 1 to 6 and n is universe from 1 to 63999.
Protocol
The Protocol command is used to set the protocol for each of the six output RJ45 jacks. The current valid protocols are DMX and RENARD.
PRotocol b n Where b is the RJ45 output jack number, from 1 to 6 and n is 1 for DMX protocol and 2 is for Renard protocol.
Baud
The Baud command is used to set the baud rate for each of the four output RJ45 jacks.
NOTE: This command is only used for the Renard protocol. Baud rate will not be displayed when
the DMX protocol is selected.
BAud b n Where b is the RJ45 output jack number, from 1 to 6
and n is 1 for a baud rate of 57,600 or 2 is for a baud rate of 115,200.
The Renard protocol refresh rate at 57,600bps for 512 channels is approximately 90ms and at
115,200bps the refresh rate for 512 channels is approximately 45ms.
The DMX protocol refresh rate is preset to 25ms.
TroubleShooting
So - you've built your new 6 Port E1.31 Bridge, connected it up to your computer and tried a quick sequence and nothing happens! There are several checks to perform in order:
Visual Inspection
The very first step involves a close visual inspection of the board. Double check that you have the correct component in the correct location and in the correct orientation. Look at every single solder connection and if some are not shiny or look suspect - reflow them to be sure.
