Q1 What does "EEPROM CORRUPT" mean?

The message "EEPROM CORRUPT" is generally caused by a Wesmaint cable or termination plug connected to the craft port while the power to the WS2000 is applied or removed. The Wesmaint cable or termination plug contains the circuitry to enable the EEPROM in the WS2000 to be written to, thus the key to making changes to the WS2000 configuration. This cable or termination plug is to be connected to the WS2000 only while viewing or making changes to the WS2000 configuration.

In most cases the WS2000 can recover from this condition without being returned to Westronic for repair. Since there are several different types of WS2000 products with different software loads, there is more than one procedure to restore the WS2000. The following procedure is based on the Rack Mount Wesmaint, Portable Wesmaint, DOS versions of the PC Wesmaint and Windows Panel software or ASCII Terminal. If using the PC Wesmaint II software, the procedure can only be done using the Wesmaint Panel Function. There are two options to recovering the WS2000. Some versions of the WS2000, such as the E2A unit, can only use the first option.

Option 1.

Put the WS2000 into Config mode make a change to the configuration. It can be any change, such as configuring a spare display. You will notice that the EEPROM CORRUPT message may scroll across the screen every time a button is pressed, this message will clear to allow you to go through the menus, just be patient. Once a change is made return the unit to Normal mode. This will cause a soft reboot, when the unit comes back up repeat the procedure and undo any changes that were made to the configuration. This should clear the EEPROM CORRUPT message.

Option 2.

In the WS2000 TABS unit and the E2A w/ TABS unit, there is a function in the command menu called INIT-DB, this will clear everything from the EEPROM and reload the factory defaults. After initializing the configuration return to normal mode to initialize the unit. Once completed the unit can be configured. All configuration settings will be lost using this method.

Note: On occasion the above methods of recovery will not work. In this case the unit must be returned to the factory for repair following the RMA procedures.

Q2 Why are the status input LEDs on with nothing connected to them?

When power is first applied to the WS2000 status input LEDs are on with nothing connected to them.

First check the numbers of the active inputs. If they are any of 25-32 or any of 57-64, look on the backplane of the WS2000 and check if jumper Z7 and/or Z9 is in place. If so, remove these straps and check if the lights turn off. If they do then it is a matter of turning off a control point. Straps Z7 and Z9 allow the controls to be internally looped back onto inputs 25-32 and 57-64, therefore, if a control is on the WS2000 will report an alarm on these points. The control relays are magnetically latched, allowing one of the relays to latch during shipping and have inputs light up when first turned up. Using the Wesmaint the controls can be turned off.

Q3 Why can't I talk to the Wesmaint using software or an ASCII terminal?

The WS2000 craft port requires specific port settings as well as a special cable. The cable is shipped with every licensed copy of the Wesmaint Software packages. Those using a ASCII terminal can order a cable from Westronic or they can build their own. Connections are described in the Maintenance Interface section of the manual, or in the table below. The table is valid for any type of WS2000. Port settings must be set at 9600 bps, 7 data bits, even parity, and one stop bit.

Q4 Why are my configuration changes not being accepted?

When using a Rack Mount Wesmaint Panel connected to P5 on the backplane on the WS2000, a terminating plug is needed to enable changes to be written to the EEPROM which is where the configuration is stored. The plug is installed on the craft port JB3.

If using a PC application, PC Wesmaint or ASCII Terminal, it is possible to view the configuration using a standard NULL modem cable, however to make changes you must have the Wesmaint Cable which has the wiring to write the changes into EEPROM. The cable is included with all PC Wesmaint software packages. If using a ASCII terminal you can buy a cable from Westronic, or build one using the table below. The table applies to all types of WS2000.
