Homer Hot Measurement and Tuning System - S-TEAM Lab

Hom.mem: Homer Analyzer memory file; it contains among others detectors correction data and Homer
frequency calibration constants.
Tun.mem: Mototuner memory file; it contains motors data and tuning stubs characterization.
IMPORTANT NOTE: Because of their individual nature, mem files must not be exchanged between individual
Homers. If Server detects a non-native mem file, the Homer Identity Error is raised. Then the following happens:
Newer Server versions (V54 and more):
If Homer Identity Error occurs, Server announces this by playing Morse code error message IDE, followed by a
standard Morse message. Server does not terminate but sets itself in a mode with reduced command set, which does
not allow measurement or motor movements, but principally only file transfers so that you are able to remedy the
situation.
Older Server versions (V53 and less):
If Homer Identity Error occurs, the Server terminates, playing first a melody (downward musical scale), then Morse
code error message IDE. Following this, file transfer server SrvDld.exe is started (one long beep – Morse code for
T).
System Configuration Files
System configuration files are text files containing user-definable Homer settings. Server program reads
configuration files after reading memory files and copies their settings to its volatile memory. Configuration file
settings therefore override the factory defaults and eventually determine Homer power-up behavior. This is
important in particular for autonomous Autotuner operation.
The structure of the configuration files is that of Microsoft Windows ini files, consisting of lines of the type
Label=Value ;Remark
where Label is the name of a variable and Value its value. It is the Value that is to be changed if needed.
The files are available to the user for editing: they can be downloaded from Homer, modified and sent back
(uploaded). In this manner, startup Homer behavior can be altered by the user.
The upload and download can be effected by:
HomSoft
HomTool servicing version of HomSoft. HomTool is an automatic, complimentary part of Homer installation.
Basic configuration files include:
Hom.cfg: Basic Homer Analyzer configuration file, defining measurement settings, like expected signal
waveform (CW, Rectified, Pulsed), signal sampling parameters (sampling rate, sampling duration, triggering
method), frequency counting parameters, etc. The file is often modified by users to adapt Homer behavior to
particular tasks. For details, see Homer Analyzer Starting Parameters.
Tun.cfg: Basic Autotuner configuration file, defining autotuning power-up behavior. The file is often modified
by users. For details, see Homer Autotuner Starting Parameters.
Rs232.cfg: Defines RS232 baudrate. Rarely needing to be modified.
Can.cfg: Defines CAN Bus baudrate. Sometimes modified by users.
Bbox.cfg: Activates and configures diagnostic internal data logging. The file may not be present.
How HomSoft Affects Configuration Settings
A HomSoft application (running in a remote PC) has its own settings, stored in Ho0.ini setup file in User Folder.
When HomSoft starts, as the first step it retrieves via communication link actual Homer parameters.
If there is no Ho0.ini file in User Folder, HomSoft settings reflect current Homer state (typically its power-up
settings).
If Ho0.ini file exists, HomSoft continues by the following steps:
- Reads settings from Ho0.ini file
- Overwrites by commands via communication link existing Homer settings by these new settings
You can then further change individual Homer settings manually by HomSoft commands.
