A serial cable moves data one bit at a time. This slow but steady method still works for many industrial machines, older network devices, and office equipment that never got a USB upgrade.
Original Serial Cable Price in Bangladesh for USB to RS232
Serial Cable Price in Bangladesh starts from Tk 890, and that is the current price of the only serial cable in stock right now. Ryans Computers sells original serial cables sourced directly from the brand, not gray-market imports. These cables connect older serial devices to a modern PC through a USB port. Price mainly depends on the connector type, the cable length, and the brand. UGREEN is the leading brand in this category at Ryans today.
How to Choose the Right Serial Cable
Before you buy, look at both ends of your existing setup. Check what port your PC or laptop has, and check what port your target device has.
Most modern laptops have no serial port at all, so you will need a USB-A connector on one end and a serial connector on the other. Older PCs, servers, and some networking gear still use a full serial connector on both sides, which usually means DB9 connectors.
Also check the driver support for the cable's chipset, since a USB to serial cable needs a small driver to show up as a COM port in Windows or Linux. Most branded cables install this driver automatically, but a cheap unbranded one may not.
Match the connector shape to your device's port before you pay, because a wrong connector will not fit, and it will not work at all even if you force it in.
Who Buys Serial Cables and Why
01
PC users buy this cable to connect compatible serial devices through a USB port, since most new laptops in Bangladesh no longer have a built-in serial port.
02
IT and technical staff use it to link compatible serial-interface devices during setup, configuration, or repair work in an office or server room.
03
Network and device technicians use it to work with compatible serial equipment such as routers, switches, and access points that still rely on a console port for first-time setup.
04
Industrial and technical users connect compatible equipment that still runs on serial interfaces, including PLCs, CNC controllers, and factory sensors that were built before USB became standard.
05
Billing counters and POS setups sometimes still run older serial-based receipt printers or weighing scales, so shop owners in Bangladesh also buy this cable to keep that hardware running.
06
Some users with older printers also need a USB-to-parallel cable instead. That is a separate product from a serial cable, so check your printer port carefully before buying.
Types of Serial Cables You Will Find
01 RS232
RS232 is the most common serial standard used in Bangladesh. It usually comes with DB9 connectors on both ends, often sold as a db9 cable, and it is built for short-distance, point-to-point communication between two devices.
02 USB
A USB to serial cable replaces the old serial port with a USB-A end, so it works on modern laptops that dropped the serial port years ago. Inside this cable is a small chip that converts USB signals into serial signals, which is why driver support matters.
03 Console
A console cable is a special type of serial cable used to configure network hardware like routers and switches, and it usually connects to a small blue or light-colored port on the back of the device.
04 DB9
A DB9 male-to-male cable, sometimes called a null modem cable, connects two computers or two serial devices directly without going through a modem.
✓
Each type serves a different job, so check your device manual or the label near its serial port before you order, since the wrong type will not complete the connection.
What to Check Before You Buy
Look at the port type on side one and side two of the cable before you add it to cart.
Check if you need a male or female connector, since the wrong gender will not plug in even if the pin count matches. A male connector has visible pins, and a female connector has holes to receive those pins.
Confirm the color and length match your setup, since a cable that is too short will strain the connection and a cable that is too long will clutter your desk.
Most stock in Bangladesh comes in a 1.5 meter length, which fits most desktop and rack setups without an extension.
Check the warranty period before payment, since original cables usually carry a 1-year warranty that covers manufacturing faults but not physical damage.
Also confirm the cable is an original product, not a clone, since a clone chipset often fails to install drivers correctly on Windows.
!
If you actually need a serial Sata power cable for an internal hard drive or SSD, that is a completely different product from a data serial cable, and it should not be confused with this category when you search or order.
