Version 3.5
update for the LZ100for Set-01 users with LZ100 version 3.x
Version 3.5
update for the LZ100New features
Version 3.5 implements the revised NMRA RP-9.3. This RP was modified to relax some timing parameters in Direct mode. Version 3.5 will allow you to use our smart 1 step address programming for new Digitrax and NCE decoders.
The DCC packet preamble was lengthened to position the LZ100 to accommodate RailCom to be released in 2003.
The LZ100 maintains important information in an internal database of all the locomotives that have been addressed by the user. This information includes for each locomotive such important information as the current speed step of the locomotive (14,27,28,128) , function status, double header or multiple unit addresses, and the last speed step transmitted. In order to guarantee this storage is maintained across operating sessions, a battery is used in the LZ100, which supplies the memory with current when the system is shut off. The message "ERR97" is intended to be displayed if the battery voltage in the LZ100 is too small to maintain this database. We found that some power supplies and some installations caused the LZ100 to incorrectly displayed the ERR97 message on startup. Version 3.5 corrects this incorrect error message.
In Version 3 the user can scroll through a stack of all locomotives in the database. We found that in some cases the information displayed in this stack was not correct. Version 3.5 corrects this stack problem.
In Version 3.0-3.2 Locomotive addresses that could be divided by 256 could not be controlled. This is fixed in version 3.5
In the "AUTO" mode the handheld sometimes displayed "Auto" each time the user plugged in a handheld. This is fixed in version 3.5.
If you have experienced one or more of these problems then we would recommend you upgrade to Version 3.5. This upgrade is accomplished by replacing a reprogrammable EEPROM in your LZ100.

How to get your upgrades within North America:
There are two options for this.
Option 1: You perform the upgrade yourself:
If you feel comfortable with replacing one or two chips that are in sockets and would like to do the upgrade yourself, we can send you an EEPROM for you to exchange. Since these parts are reprogrammable we ask that you return the parts you replace within 30 days.
Option 2: We perform the upgrade for you:
If you like we will perform the upgrade for you, check out your system and quickly return it to you. We ask that you include a check for $10.00 US to cover shipping and handling.
The cost for Canadian users is $20 USD, paid by credit card only.
To find your current LZ100 Version Number:
With an LH100 enter " F 9 8" The current version number is displayed in the LH100's display.With an LH90 or LH200 go to the menu "SYS" and enter "13" The current version number of the LZ100 is displayed in the LH90's or LH200's display.
The version 3.5 upgrade offer is only valid for LZ100 command stations, which have a current version of 3.0, 3.1, or 3.2. If you need an update of your LZ100 with version 1.x or 2.x to version 3.5, click please here.
To receive your upgrade please fill in our upgrade form.
Open the LZ100 by removing the screws on either the front or back plate and remove the printed circuit board from the case.
Remove the EEPROM (the part inside the white box n the figure below). This is very simple if you use a small screwdriver between bases and IC as a lever. Go slow as you do not want to bend the pins of the EEPROM.
Insert the new EEPROM into the socket you removed the old EEPROM from. Be careful to ensure that Pin 1 lines up properly. The position pin of the 1 lines up as shown on the diagram on the right beside the photo.
Replace the board back in the LZ100 case and replace the screws.
On power-up reset the system. This is accomplished by entering locomotive 00 in the handheld display and pressing the 4 key 25 times. Then power down and power up.
