Instrument data.
Connected operation.
Connect compatible serial instruments and current-loop measurements to a compact cellular DTU, with edge processing, online monitoring and supported remote operations.
RS485 and TTL interface options
Bring compatible serial instruments and embedded equipment into the data path. Agree the electrical connection, device protocol and readable data points for the supplied interface arrangement.
4–20 mA transmitter acquisition
Connect compatible external current-output transmitters. Define the instrument range, engineering units and current-to-value mapping so online readings retain their physical meaning.
Acquisition and processing at the edge
Acquire and process field data close to the connected equipment. Specify the required data interpretation and update behaviour for the delivered application.
Cellular data transmission
Use a 4G cellular connection for remote data communication. Select the module, frequency bands, antenna arrangement and SIM service for the installation country and network.

MONITORING & CONTROL
Acquire. Transmit.
Review and respond.
Build a traceable path from the instrument output to the online measurement and any permitted remote command. Verify the measurement and physical equipment response separately.
01
Define and acquire the measurement
Identify the instrument, electrical interface and data format. For serial points, document the readable data map; for current-loop points, define the source range, units and scaling.
02
Transmit over the selected network
Match the cellular variant, antenna and SIM service to the site. Define acquisition and reporting requirements separately, then check the installed connection and update behaviour.
03
Review online data and alerts
View uploaded measurements in Hitelecom Cloud. Check asset identity, engineering units and configured threshold alerts against the source instrument during commissioning.
04
Execute supported remote operations
Use only commands documented for the connected equipment and agreed for the installation. Verify the physical result or instrument readback separately from command transmission, and confirm operation after a firmware upgrade.
APPLICATIONS
Connected instruments.
Across the operation.
Eight application areas, each with five instrument-connection tasks, show where a compact cellular DTU can bring field data online. These 40 tasks are selection examples, not a channel count or a promise that all tasks run in one device. Select the fitted interface arrangement, compatible external instruments and required data exchanges for each installation. Remote actions apply only where the connected equipment exposes a documented, supported command interface.

PLATFORM & INTEGRATION
Your instrument data. Visible in Hitelecom Cloud.
View uploaded monitoring data online and receive alerts when configured thresholds are exceeded. Give each instrument a clear asset identity, engineering units and defined update behaviour. For a customer-platform project, agree the supported communication method and data mapping for the delivered device configuration.
Online measurements: review uploaded serial-instrument values and current-loop measurements in the selected monitoring view, with source ranges, units and asset names defined for each point.
Threshold alerts: set the monitoring limits and notification workflow. Verify the trigger, recipient and delivery during commissioning; data availability depends on the reporting profile and network connection.
Remote operations: define the equipment commands, authorization and available readback before enabling remote use. Keep the equipment’s local controls and independent protection functions in place.
ANSWERS FOR YOUR PROJECT
Practical questions.
Before you connect.
Answers for serial and current-loop interfaces, cellular deployment, online monitoring and supported remote operations.
What is the HR-10 series designed to do?
It is a compact wireless data transmission unit (DTU) for acquiring and transmitting compatible instrument and equipment data. RS485, TTL and 4–20 mA interface options, edge processing, cellular communication, cloud monitoring, supported remote control and firmware upgrades connect the field instrument to the operating workflow.
Are RS485, TTL and 4–20 mA all fitted at the same time?
Confirm the physical ports, quantities and supported combinations for the ordered version against your instrument list. RS485, TTL and 4–20 mA identify interface options; they do not establish the fitted combination. The 40 application tasks are selection examples, not 40 channels.
Does RS485 mean the unit supports every serial instrument or Modbus device?
No. RS485 defines a physical interface. Device protocol, addressing, serial settings, data representation and supported read or write operations must also match. Submit the instrument communication manual and data map for an integration review; do not assume a protocol solely from the RS485 label.
What must be checked before connecting a TTL device?
Confirm the electrical logic levels, transmit/receive pin assignment, grounding, cable arrangement and serial data format for both devices. A TTL label alone does not establish a voltage level, isolation, connector or supply output.
How are 4–20 mA transmitters connected and displayed?
Use the current-loop interface specified for the supplied version and a compatible external transmitter. Confirm loop wiring, transmitter supply, supported input limits and scaling. Define the transmitter range and engineering units, then verify online values against the source instrument and reference points during commissioning.
Can I view measurements and receive alerts in Hitelecom Cloud?
Yes. Hitelecom Cloud supports online viewing of uploaded monitoring data and alerts when configured thresholds are exceeded. Configure asset names, units, monitoring limits and the notification workflow. Data availability and notification timing depend on the reporting profile and network connection.
What remote control can the HR-10 provide?
Remote control applies to commands supported by the connected equipment and the delivered device configuration. Agree the command path, authorization, local priority and available readback before enabling it. A DTU does not by itself establish a relay output or a direct load connection, and command transmission does not prove the equipment has moved or changed state.
Which cellular networks and countries can it be used in?
Select the cellular variant for the installation country and network. The 4G, 5-mode / 13-band reference configuration requires confirmation of the exact module, frequency bands, operator service and destination requirements for the ordered version. This description does not guarantee every network, worldwide roaming or future network availability.
Can firmware be upgraded remotely?
Remote firmware upgrades are supported. Use the approved firmware for the delivered hardware, maintain power and the required connection, and follow the site maintenance procedure. Verify instrument communication, scaling, uploads and permitted operations after the upgrade.
What do the hardware and software watchdogs provide?
They support recovery from defined abnormal operating states. Confirm the reset, reconnection and restart behaviour for the selected configuration during commissioning. Watchdogs do not replace equipment protection or establish uninterrupted communication.
Can it integrate with our own monitoring platform?
Customer-platform integration can be reviewed against the communication methods supported by the supplied device and software. Agree the transport, data format, instrument mapping and permitted commands for the project. Do not infer a particular cloud protocol or API from the cellular or serial interface alone.
What information is needed to select an HR-10 configuration?
Provide the installation country, instrument models, interface manuals, data maps and point quantities. Include current-loop ranges, required remote commands, power source, site conditions, acquisition/reporting needs and target platform. These details establish the fitted interface arrangement, integration scope and commissioning checks.
