DTECH DT-5048 8 Port RS232 Splitter – 1 DB9 Input to 8 DB9 Outputs

The DTECH DT-5048 8 port RS232 splitter lets one host control eight serial devices from a single DB9 port. It’s built for larger control, security and industrial systems where one PC, controller or recorder needs to reach a full row of displays, panels, instruments or terminals. There’s no need for extra interface cards, more PCs or custom software. One DB9 female input feeds eight DB9 male outputs inside a rugged metal enclosure, powered from DC 5V.

Why Choose This 8 Port RS232 Splitter for Your Project

Most serial-controlled equipment has only one RS-232 port, and so do most hosts. When a site has eight devices that need the same commands, adding controllers or USB-to-serial adapters quickly gets expensive and hard to maintain. This 8 port RS232 splitter solves it in one box, so a single command reaches every device. There’s only one unit to install, label and support.

• One host, eight devices: send commands from one PC, control processor or NVR to eight serial devices at the same time.
• Works in reverse too: the eight ports can connect to eight computer hosts to share control of a single RS-232 device. This is useful for shared instruments or multi-operator stations.
• Scales past eight: multiple units can be cascaded when a project needs more outputs.
• Built for tough sites: the matte metal shell resists wear, heat, shock and drops, and gets rid of heat quickly, so it suits plant rooms, control cabinets and industrial panels.
• Simple to commission: the hardware design needs no drivers or software on the host.
• Backed by warranty: covered by a 1-year manufacturer warranty.

Where Integrators Use the DT-5048 8 Port RS232 Splitter

System integrators, MEP and electrical contractors, facility management teams and industrial engineers use an 8 port serial splitter wherever one source needs to reach many endpoints. Typical applications include:

• Industrial control and automation: link one PLC, PC or HMI to eight instruments, drives or terminals.
• Digital instrument data collection: connect meters, scales and sensors to a shared collection point.
• Access control systems: send a controller’s serial output to multiple readers, panels or logging terminals.
• Environmental and noise monitoring: link noise detectors and monitors to several recorders.
• SMS controllers and terminal equipment: send serial alerts and commands to eight devices at once.
• AV, signage and control rooms: power on, switch and control up to eight serial-controlled displays or projectors from one processor.
• Laptops and PCs: configure or test a batch of serial devices from one notebook in the workshop or on site.

How to Get the Best Results from Your 8 Port RS232 Splitter

The host sends to all eight outputs at once. This is ideal for broadcast-style control, such as powering on displays or sending the same command to every device. If your devices also report back, poll them one at a time so their replies don’t collide. Most control processors and data-collection software do this by default. Keep each cable run within about 15 metres, and set the same baud rate and data format on the host and every device. For background on serial wiring, see these overviews of the RS-232 standard and the DB9 (D-subminiature) connector.

Installation Tips

1. Connect your host (PC, controller or NVR) to the DB9 female input.
2. Connect up to eight serial devices to the DB9 male outputs, labelling each cable as you go.
3. Connect the DC 5V power supply.
4. Match the baud rate and data format on the host and all devices, then test each port in turn.
5. For more than eight devices, cascade a second unit from one of the outputs.

Frequently Asked Questions

Does the 8 port RS232 splitter need drivers or software?

No. It’s a hardware device, so it works with any operating system or control platform and there’s nothing to install.

What power does it need?

It runs on DC 5V.

Can eight computers control one device?

Yes. The DT-5048 also works in reverse, so up to eight hosts can connect to a single RS-232 device.

How far can I run the cables?

The communication distance is approximately 15 metres. Use good-quality shielded serial cable for the best results.

Can I connect more than eight devices?

Yes. Multiple units can be cascaded to reach more devices.
