5. Find the setup of “RemoDAQ-8000 Utility” and run it.

6. Please follow the steps of setup program then you can successfully install the RemoDAQ-8000 Utility

2.3 Basic configuration and hook-up

Before placing a module in an existing network, the module should be configured. Though all modules are initially configured at the factory, it is recommended to check that the baud rate is set correctly.

Default Factory Settings

Baud rate： 9600 Bit/sec.

Address： 01 (hexadecimal)

Checksum：disable

The basic hook-up for module configuration is shown below.

Figure 2-2 Layout for Initialization the RemoDAQ module

The following items are required to configure a module：a

8

RemoDAQ-8054 User’s Manual

RemoDAQ converter module, a personal computer with RS-

232 port (baudrate set to 9600) and theRemoDAQ utility software.

Configuration with the RemoDAQ Utility Software

The easiest way to configure the RemoDAQ module is by using the RemoDAQ utility software：an easy-to-use menu- structured program will guide you through every step of the configuration.

Configuration with the RemoDAQ command set

RemoDAQ modules can also be configured by issuing direct commands from within a terminal emulation program that is part of the RemoDAQ utility software.

The following example guides you through the setup of an analog input module. Assume that RemoDAQ-8054 still has its default settings (baud rate 9600 and address 01h). Before the module is reconfigured, it is first requested to send its default settings.

To change the configuration setting of the analog input module, the following command is issued：

%0107400600(cr)

% = change configuration

01 = target module at address 00 to：

07 = change address to 07 hexadecimal

40 = set input range to Type 40

06 = set baud rate to 9600

00 = set integration time to 50 ms (60 Hz) disable checksum set data format to engineering units

9

RemoDAQ-8054 User’s Manual

(See Chapter 3, Command Set for a full description of the syntax of the configuration command for module)

When the module received the configuration command it will respond with its new address：!07(cr)

NOTICE： All reconfiguration except changing of baud rate

and checksum values can be done dynamically, i.e. the modules need not to be reset. When changing the baud rate or checksum, these changes should be made for all connected devices. After reconfiguration, all modules should be powered down and powered up to force a reboot and let the changes take effect.

2.4 Baudrate and Checksum

RemoDAQ modules contain EEPROMs to store configuration information and calibration constants. The

EEPROM replaces the usual array of switches and pots required to specify baudrate, input/output range etc.

All of the RemoDAQ modules can be configured remotely through their communication ports, without having to physically alter pot or switch settings.

Forcing the module in the INIT* state does not change any parameters in the module’s EEPROM. When the module is in the INIT* state with its INIT* and GND terminals shorted, all configuration settings can be changed and the module will respond to all other commands normally.

Changing Baud rate and Checksum

10

RemoDAQ-8054 User’s Manual

Baud rate and checksum settings have several things in common：

¾ They should be the same for all modules and host computer.

¾ Their setting can only be changed by putting a module in the

INIT* state.

¾

Changed settings can only take effect after a module is rebooted

To alter baudrate or checksum settings you must perform the following steps：

¾ Power on all components except the RemoDAQ Module.

¾ Power the RemoDAQ module on while shorting the

INIT* and GND terminals

¾ Wait at least 7 seconds to let self calibration and ranging take effect.

¾ Configure the checksum status and/or the baud rate.

¾ Switch the power to the RemoDAQ Module OFF.

¾ Remove the grounding of the INIT* terminal and power the module on.

¾ Wait at least 7 seconds to let self calibration and ranging take effect.

¾ Check the settings (If the baud rate has changed, the settings on the host computer should be changed accordingly.)

3 Command Set

Introduction

To avoid communication conflicts when several devices try to send data at the same time, all actions are instigated by the host computer. The basic form is a command/response protocol with the host initiating the sequence.

When modules are not transmitting they are in listen mode.

The host issues a command to a module with a specified address and waits a certain amount of time for the module to respond. If no response arrives, a timeout aborts the sequence and returns control to the host.

Changing RemoDAQ’s configuration might require the module to perform auto calibration before changes can take effect. Especially when changing the range, the module has to perform all stages of auto calibration that it also performs when booted. When this process is under way, the module does not respond to any other commands.

The command set includes the exact delays that might occur when modules are reconfigured.

Syntax

[delimiter character][address][command][data][checksum]

[carriage return]

Every command begins with a delimiter character. There are four valid characters：a dollar sign $, a pound sign #, a percentage sign % and an at sign @.

12

RemoDAQ-8054 User’s Manual

The delimiter character is followed by a two-character address (hexadecimal) that specifies the target module. The actual two-character command follows the address.

Depending on the command, an optional data segment follows the command string. An optional two character checksum may be appended to the total string. Every command is terminated by a carriage return (cr).

Calculate Checksum：

1. Calculate ASCII sum of all characters of command(or response) string except the character return(cr).

2. Mask the sum of string with 0ffh.

Example：

Command string：$012(cr)

Sum of string=‘$’+‘0’+‘1’+‘2’=24h+30h+31h+32h=B7h

The checksum is B7h，and [CHK] = “B7”

Command string with checksum：$012B7(cr)

Response string：!01200600(cr)

Sum of string：‘!’+‘0’+‘1’+‘2’+‘0’+‘0’+‘6’+‘0’+‘0’

=1h+30h+31h+32h+30h+30h+36h+30h+30h=1AAh

The checksum is AAh，and [CHK] = “AA”

Response string with checksum：!01200600AA(cr)
