1 Introduction
The RemoDAQ-8000 Series is a set of intelligent sensor to
computer interface modules containing built in microproces-
sor. They are remotely controlled through a simple set of
commands issued in ASCII format and transmitted in RS-485
protocol. They provide signal conditioning, isolation, ranging,
A/D and D/A conversion, data comparison, digital commun-
ication, timer/counter, wireless communication, collection
AC and other functions.
RemoDAQ-8054 is the 8-channel cable ON/OFF detecti-
on module that are used in telecommunications profession
specially, LED shows the ON/OFF state of 8-channel cable,
each channel has a LED state of instructing this road. When
cable shorts , LED OFF;When cable broken road, LED ON.
Its power supply also with other module is difference, for
44~58Vdc.

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.
¾Changed settings can only take effect after a module is rebooted
To alter baudrate or checksum settings you must perform the
following steps：
¾Power on all components except the RemoDAQ Module.
¾Power the RemoDAQ module on while shorting the
INIT* and GND terminals
¾Wait at least 7 seconds to let self calibration and ranging
take effect.
¾Configure the checksum status and/or the baud rate.
¾Switch the power to the RemoDAQ Module OFF.
¾Remove the grounding of the INIT* terminal and power
the module on.
¾Wait at least 7 seconds to let self calibration and ranging
take effect.
¾Check 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)
