The reason for the creation of new version of the document:
•
At 12.2015 GC5 released a new hardware version for MIX module with more
powerful processor and USB port. For this hardware and for all MINI series
devices we released firmware 4.0 which contains bug fix, firmware
improvement and also rebuilt BACnet protocol (new object, COV).
•
All modules purchased as of 2016 have improved versions of the relays, which
allow to increase the capacitive load. Details of the technical specifications.
•
Note: This document was created for devices with firmware version 4.0 and
above. For previous firmware version please read Modbus Manual version 1.0.
•
Changes in Document:
•
Added to the technical specifications information about the capacitive load
relay.
•
Added to the technical specifications information about load Triac Outputs.
•
Added description of the new MINI module 4x Triac Outputs: 4TO-H and 4TO-H-
IP.
•
MINI - 4I40-H and 4I40-H-IP Module built in application: Change of logic in the
Time relay mode. Now, timer counts from falling edge (before from rising
edge).
•
New gateway functionality blocking Send Modbus Error.
•
Changed tables with PT1000 and NI1000 for more accurate, because new FW
measure resistance for this sensors with accuracy 0,1 Ω.

2017.01.03
The reason for the creation of new version of the document:
New functions:
•
New HVAC functions Heating and Cooling in 4U4O based on output
thermostatic control with a setpoint and differential value setting;
•
Added new input mode for 4I4O: Time Relay NC [ms], Time Relay NO and NC in
seconds, Input Forwarding;
•
Added new input mode for 4U4O: Ordinary IO, Monostable Relay, Bistable Relay,
Time Relay NO and NC [ms], Time Relay NO and NC in seconds, Input
Forwarding, Heating, Cooling with corresponding BACnet objects and Modbus
registers;
•
Added reset output to default after input mode change in 4U4O and 4I4O;
Improvements:
•
Improved BACnet COV Increment can now have values with resolution 0.1;
•
Added BACnet COV Increment access (read/write) through USB;
•
Added power Led flashing after IO watchdog triggered;
•
Changed IO watchdog reset after read/write registers through USB;
•
Added immediately detecting sensors short circuit and disconnection
regardless of filter settings on universal inputs;
Fixed bugs:
•
Fixed bug with Stop bits, was always 1;
