14

RemoDAQ-8031A/33A/34 User’s Manual

your drive of CD-ROM is F：then change the drive to F：

6. Please follow the steps of setup program then you can

successful to 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

15

RemoDAQ-8031A/33A/34 User’s Manual

The following items are required to configure a module：a
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 menu­structured 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-8031A 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：

%0107200600(cr)

% = change configuration
01 = target module at address 00 to：
07 = change address to 07 hexadecimal
20 = set input range to Type 20
06 = set baud rate to 9600
00 = set integration time to 50 ms (60 Hz)

disable checksum

16

RemoDAQ-8031A/33A/34 User’s Manual

set data format to engineering units

(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 ports
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 port 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.

17

RemoDAQ-8031A/33A/34 User’s Manual

Changing Baud rate and Checksum

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 effe ct after a module is reboote d.

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.)

RemoDAQ-8031A/33A/34 User’s Manual

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][checks u m]
[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 @.

19

RemoDAQ-8031A/33A/34 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)
