Technical Manual MiniMEP Data Loggers
page 11
The values recorded by the MiniMEP can be retrieved via its
interfaces and processed by PC-Software. Here are the most
important szenarios in practise:
• Networking together with other controllers
The MiniMEP is connected to a controller network via its RS-
485-interface which allows remote access from a host. In
this case, each unit on the bus gets an individual address
within 1 and 78 (Parameter '
address'
on parameter page).
• Direct PC connection
As a low cost alternative for a serial printer, a PC can be
connected to the RS-232-interface.
• Direct PC connection of several MiniMEP
Electrical connection must be done as described above via
RS-485 interface. The PC must be equipped with an RS-485-
interface, or an Interface Converter of the series SSC must be
used.
Processing of recorded data / Unlock unit for use with PC-Software
PC-Software
If the MiniMEP is connected to controller network, the software
"
COOLVision
" is used normally. If a PC should operate with one
or more MiniMEP exclusively, the software "
CV-Scheduler
" is
recommended.
Unlock unit for use with PC-Software "CV-Scheduler"
If a MiniMEP is intended to operate with software "CV-
Scheduler", an unlock code must be entered while start-
up. You get this unlock code with the software, please see
software manual for further information.
Without this code, retrieve and processing of data with the
software is impossible.
How to check if your MiniMEP is unlocked for CV-Scheduler
software:
- Access parameter page,
- Select parameter 'software',
- If the unit is unlocked, you will find the additional info
"pro" behind the software version.
