# 4. 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.

# 5. 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 discrete input/output 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>Reset Status</td><td>$(Addr)5</td></tr><tr><td colspan="2">Functional Command</td></tr><tr><td>Digital Input</td><td>$(Addr)6</td></tr><tr><td>Digital Output</td><td>#(Addr)T(OdataA)(OdataB)(OdataC)</td></tr><tr><td></td><td>#(Addr)(Port)(OutData)</td></tr><tr><td></td><td>#(Addr)(Port)(ChannelNo)(BitData)</td></tr><tr><td>Synchronized Sampling</td><td>#**</td></tr><tr><td>Read Synchronized Data</td><td>$(Addr)4</td></tr><tr><td>Set Programmable I/O Mode</td><td>$(Addr)S(IOSts)</td></tr></table>

<table><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><tr><td>I/O Polarity Setting</td><td>~(Addr)CP(State)</td></tr><tr><td>Read Polarity Setting</td><td>~(Addr)CR</td></tr></table>

\* The module accepts 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.
