\*The module is in DEFAULT mode when DEFAULT\* pin connected to GND while applying power on the module.

\*Do not apply any power signal to DEFAULT\* pin, just left it open or connected it to GND.

# 4. Functional Block Diagram

![Based on the provided block diagram, here is the accurate description of the labeled blocks and their connections:\n\n**Labeled Blocks:**\n*   Power Regulator & Filter\n*   Watchdog/Power Failure Supervisor\n*   RS-485 Rec/Drv\n*   Micro Processor\n*   ADC\n*   Mux\n*   EEPROM Config Data Safe Value\n*   1-bit Digital Input\n*   Terminal Block (indicated by the screw terminals on the right)\n\n**Connections and Flow:**\n*   **Power:** 'Power Input +10V ~' connects to the 'Power Regulator & Filter'. This block outputs '+ 5V' and 'GND'.\n*   **Micro Processor:** This central block has bidirectional connections to the 'Watchdog/Power Failure Supervisor' (above) and 'RS-485 Rec/Drv' (left). It receives input from the 'EEPROM Config Data Safe Value' (bottom left) and the '1-bit Digital Input' (bottom right). It outputs to the 'ADC'.\n*   **RS-485:** The 'RS-485 Rec/Drv' block has external lines labeled 'Data' pointing to the left.\n*   **ADC & Mux:** The 'ADC' connects to the 'Mux'. The 'Mux' receives input labeled '3 RTD Input Channels' and connections from the terminal block (lines with fuse symbols originating from '+ IEXC' and '- IEXC' point left into the Mux).\n*   **Terminal Block:** The vertical block on the right lists terminals '+ IEXC', '+ SENS', '- SENSE', '- IEXC', and 'GND'. It includes the text '2, 3, 4 Wires' at the bottom. A resistor coil symbol connects the '+ SENS' and '- SENSE' terminals.\n*   **Digital Input:** An input labeled 'Default *' connects to the '1-bit Digital Input'.](.csheet-en/5bb6684cc6db09265bddcd632d83e6b78215275c8139d9bdabbc9c3292fa015e.jpg)

# 5. Installation

# Equipment for Installation

A existing RS-485 network

NuDAM modules

DC Power supply (+10V\~+30V)

Wires for power, communication and I/O signal

# Installation Procedure

1. Configure every single NuDAM module under the administration utility.
2. The baud rate setting and calibration procedure must be done under the DEFAULT\* mode.
3. The baud rate and check-sum status must be identity with the application network. The address ID must not be conflict with other modules on the network.
4. Plug the new module to the existing network.
5. Use the NuDAM administration utility to check the entire network.

# 6. Command Set

There are three categories of NuDAM commands. The first is the general commands, including set configuration command, read configuration, reset, read module‘s name or firmware version, etc. Every NuDAM can response to the general commands. The second is the functional commands, which depends on functions of each module. Not every module can execute all function commands. The third is the special commands including functions about the programmable watchdog timer, safe values, and the programmable leading code. All the commands used in the NuDAM analog input module are list in the following table

<table><tr><td>Command</td><td>Syntax</td></tr><tr><td colspan="2">General Command</td></tr><tr><td>Set Configuration</td><td>%(OldAddr)(NewAddr)(InputRange)(BaudRate)(DataFormat)</td></tr><tr><td>Read Configuration</td><td>$(Addr)2</td></tr><tr><td>Read Module Name</td><td>$(Addr)M</td></tr><tr><td>Read Firmware Version</td><td>$(Addr)F</td></tr><tr><td>Software Reset</td><td>$(Addr)RS</td></tr><tr><td colspan="2">Functional Command</td></tr><tr><td>Span Calibration</td><td>$(Addr)0</td></tr><tr><td>Offset Calibration</td><td>$(Addr)1</td></tr><tr><td>Read Analog Data Channel 0</td><td>#(Addr)</td></tr><tr><td>Read Analog Data From Channel N</td><td>#(Addr)(Channel No)</td></tr><tr><td>Read All Analog Data</td><td>#(Addr)A</td></tr><tr><td>Enable/Disable Channel for Multiplexing</td><td>$(Addr)5(ChannelVal)</td></tr><tr><td>Read Channel Status</td><td>$(Addr)6</td></tr><tr><td>Open RTD Detection of Channel N</td><td>$(Addr)B(ChannelNo)</td></tr><tr><td>Enable/Disable Open RTD Detection</td><td>$(Addr)O(Status)</td></tr><tr><td colspan="2">Special Command</td></tr><tr><td>Read Command Leading Code Setting</td><td>~(Addr)0</td></tr><tr><td>Change Command Leading Code Setting</td><td>~(Addr)10(C1)(C2)(C3)(C4)(C5)(C6)</td></tr><tr><td>Set Host Watchdog / Safety Value</td><td>~(Addr)2(Flag)(TimeOut)(SafeValue)</td></tr><tr><td>Read Host WatchDog / Safe Value</td><td>~(Addr)3</td></tr><tr><td>Host is OK</td><td>~**</td></tr></table>

\* The module accepts calibration command, baud rate and checksum configuration setting under the DEFAULT\* mode.
\* Please refer the manual in PDF file format in the CD for detail description of these commands.
