1.0     DLPCIe General Operation & Applications

The DLPCIe continues the functionality of the current DLPC/DLPCI product line. It offers both the new addition of DH-485 as well an extra Serial com port. New is the ability to have the DLPCIe an extra serial communication port that most desktops don’t have.

The DLPCIe has two communication ports. Channel A is designed to connect to you industrial network, either A-B’s DH+ or DH-485 networks. Channel B is used to connect to your serial DF1 protocol.

Configuration of the operating parameters is done quickly and easily by the EQ32 windows based software shipped with the unit or available on the Equustek Website.

Currently there are two standard DLPCIe products available to allow access to A-B’s DH-485 and DH+ network. Contact Equustek Solutions to see if the DLPCIe is the correct device for your communication needs.

The DLPCIe-DF1 is a two port device that allows your DF1 driver to communicate with ones on an Allen Bradley DH-485 or DH+ network. The DF1 model is a direct replacement for the 1770-KF3 for DH-485 and 1770-KF2 for DH+ and allows your PCs or Laptops access to any node on the corresponding Allen Bradley network.

Once pressed the message “This *WILL* overwrite DATALINK system code enter (Y/N) to proceed” will be displayed. Hit “Y” and the next message will appear telling you that it is alright to send the new firmware to the Flash; ERASING FLASH, PLEASE WAIT...


Once the message to send the firmware appears then either click on the “Burn Flash System File” button to select the .txt file to send, or send the Text File under HyperTerminal.

Wait for an “*A-OK* BURN COMPLETE!” message to appear.
Memory Dump
This is used to display the RAM memory of the DLPCIe. This should only be done after contacting Equustek Solutions to debug problems. .
Off-Line Diagnostics
Starts a series of tests to test the DLPCIe’s hardware and should only be done if instructed so by a trained person.
Debug Mode
Starts up a DLPCIe internal Debug mode that can be used by trained personnel to debug problems and check hardware configuration and operation.
Firmware Version
Once selected the current DLPCIe model and version numbers will be displayed. Can be used to check the correct firmware was burnt into the Flash or if the DLPCIe has the most up to date firmware in the Flash.
Does a soft “software” reset of the unit to put it online.5.0 Switch and LED Indicator Functions.

5.0     Switch and LED Indicator Functions

5.1     Switch Functions
The Configure pushbutton takes the DLPCIe out of On-Line operation mode and puts it in the BIOS Manager mode. The BIOS Manager mode also allows for configuration parameters to be downloaded from or uploaded to the Windows based configuration software (EQ32). When this mode has been entered the STATUS LED will be RED and BUS LED will be Green while NET LED will be off. To put the unit back On-line use option 7 from the BIOS menu or can power off then on the PC.

5.2     Indicator Functions
5.2.1     Power-Up and Reset Sequence
On Power-up the DLPCIe executes a self diagnostic check-up or the ram and flash firmware. The correct LED indicator sequence to show the DLPCIe is functioning properly is as follows: After all LEDS go out.

RED for 0.5 seconds
Green for 0.5 seconds
Green for 0.5 seconds
After this sequence the DLPCIe goes into the On-line mode of Operation. The LED indicators will behave in the certain way defined by the DLPCIe model used. Most likely all LEDS will be off waiting for communication on its channels.

5.2.2     Normal On-line Operation
The following is a description of the normal operation of the Channel Leds on the DLPCIe.

Description of Operation
Solid Green when on line on DH+ or DH485 Network.
Flashes or solid Green if there is activity of the DF1 side.
Flashes RED for 0.5 seconds if a NAK is received or transmitted in DF1 protocol. Will also flash RED if duplicate node address on DH+/DH485 exists.

5.2.3     On-Line, Power-Up and Reset Errors
