Equipment's Manual Uses Symbols

Introduction
IOMOD HT is used for temperature and humidity data monitoring and relay control over Modbus. Device is also
capable of switching relays automatically (thermostat function) as configured.
Features
• Temperature and humidity sense with ±0,1 % and ±0,1 °C accuracy;
• Temperature sensing range from -10 up to 60 °C;
• Humidity sensing range from 0 to 100%;
• Two Relays which can be configured to turn on automatically on humidity or temperature triggers (only Advanced
version);
• Relays automation configuration over USB or Modbus;
• Configurable Modbus settings, such as Slave ID, Baudrate, Parity and stop bits, RS485 terminating resistor, etc.
• Firmware Upgrade over USB;
• Two connectors for power supply and for RS485, for easier device connection on one line;
Device working information
IOMOD uses Modbus (RTU) protocol over RS485 connection, which can be used with cable length up to 1500 meters
and connect up to 30 devices on one line. Default Modbus settings are: 9600 baudrate, 8N1, Slave address - 1.
To read temperature and humidity, user can use device with default settings without configuring it. To read humidity,
send 04 Modbus command (Read Input Registers) with resolution of first register (0). Returned value will be measured
in % and will be multiplied by 10, to show one decimal place. To read temperature, send 04 (Read Input Registers)
with resolution of second register (1).
Returned value will be measured in °C and will be multiplied by 10. To enable thermostat function, user can configure
device over USB or over MODBUS. Configurable options shown in table below.

Technical Information

IOMOD HT has integrated 120Ω termination resistor which can be enabled or disabled over USB configuration. It is
recommended to use termination at each end of the RS485 cable. See typical connection diagram on Fig. 5.1.
Fig. 5.1.
IOMOD 8DI8DO has 1/8 Unit load receiver which allows to have up to 256 units on line (compared to standard 32
units). To reduce reflections, keep the stubs (cable distance from main RS485 bus line) as short as possible when
connecting device. Figure 5.2 shows explanation on device connection.
Fig. 5.2
Device connection

a. Driver installation
Device requires USB drivers to work as virtual com port. First-time connection between device and computer could
result in “Device driver software was not successfully installed” error.
Fig. 6.1
User then manually installs drivers by selecting downloaded driver folder:
Go to Control Panel -> Device Manager;
Select failed device;
Press “Update driver software”; following screen should appear:
Fig. 6.2
Select “x86” driver for 32bit machine, or x64 for 64bit machine. If not sure, select root folder (folder in which x64 and
x86 lays inside).
Fig. 6.3
b. IOMOD HT configuration with PuTTY terminal
Configuration of IOMOD device is done through CLI (Command Line Interface) on virtual COM port. Drivers needed for
MS Windows to install VCOM will be provided. To open up CLI simply connect to specific V-COM port with terminal
software (advised to use PuTTY terminal software. If other software is being used, user might need to send <return>
symbol after each command). When connected user should immediately see main screen:
Configuration over USB

Fig. 6.4
Navigation is performed by sending number to terminal. User then proceeds by following further on-screen
instructions. For example, to set Baudrate, press [2] to enter Baudrate screen; press [1] to edit; enter new
configuration; press [RETURN] to save, or [ESC] to cancel changes. When done, press [0] (exit) before disconnecting
device. Default values is set by pressing [7] on main screen, and confirming changes [1]. If accidentally closed the
terminal window, user can connect terminal program again, and press any key on keyboard to show up main menu.

d. Firmware upgrade over USB
To update device firmware user must enter main configuration menu.
Enter Firmware update screen by pressing [4];
Confirm update by pressing [1];
Device now enters Firmware Upgrade mode.

It is recommended to close terminal window when entered firmware upgrade mode.
Device reconnects as mass storage device:
Fig. 6.5
User then must delete existing file “firmware.bin”, and simply upload new firmware file by drag and drop.
Fig. 6.6
Reconnect device, and check firmware version.
e. Testing With “THE VINCI” software
To test IOMOD HT with default settings, user connects device through RS485 to Modbus master. Example will show
“The Vinci Expert” as serial interface converter and adapter to PC with “The Vinci” software. Default settings for
Modbus – 9600 baudrate; 8 data, no parity, 1 stop bit. When opening “The Vinci” software, choose Modbus serial –
Master mode. In settings tab, choose station number (default – 1); configure tags (as described in section 2. Device
working information); Press start and go to “Statistic” tab:
