Mascom International stocks the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable at KSh 1,600, brand new and sealed, in a 1.5m length with gold-plated plugs. A USB-A plug goes into your laptop, and a 9-pin DB9 male connector, with its pins exposed, pushes into the matching serial socket on the device. A Prolific PL2303 chip handles the conversion at up to 1Mbps. The UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable is on the shelf at Old Mutual Building, First Floor Room 4, Kimathi Street, Nairobi CBD, ready for walk-in buyers and same-day Nairobi delivery.
Designed for network engineers, field engineers, ISP installers and factory maintenance crews, the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable handles a job that current laptops cannot do alone. Routers, managed switches, firewalls, UPS management cards and PLCs often take setup commands only through a serial socket. Without a serial port, an engineer is stuck when a router loses its settings at a client site. With this cable and a terminal program such as PuTTY, you open the device console, restore the configuration and get the client back online before the end of the visit.
Where most Nairobi electronics shops offer a single unbranded serial lead and leave you to guess the chip, Mascom International carries the genuine UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable with a 6-month warranty and both connector genders in stock. At Mascom International, we're seeing steady demand from ISP teams rolling out fibre in Kilimani and Upper Hill and from technicians servicing plants in Athi River. Order on WhatsApp for pay-on-arrival delivery across Kenya, or bring your laptop in and test the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable at our counter.
Common Questions About the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable
How much is the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable 1.5m in Kenya?
The UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable 1.5m sells for KSh 1,600, brand new and sealed, at Mascom International in Nairobi CBD. That figure includes a 6-month warranty on manufacturing defects and pay-on-arrival delivery anywhere in the country. The female version of the UGREEN CR104 costs exactly the same, so there is no price gap between the two. Choose by the shape of the port on your equipment, and ask us on WhatsApp if you are unsure which one fits.
Can I use the UGREEN CR104 male cable to configure a Cisco router or managed switch?
Yes, the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable works for router and switch setup when paired with the device's own console lead. Many Cisco and similar devices ship with an RJ45-to-DB9 console cable whose DB9 end is female, which accepts this male plug. Open PuTTY or another terminal program, choose the new COM port, and set the baud rate the device expects, often 9,600. Network engineers tell us it is the first cable they pack for a site visit.
What is the difference between the UGREEN CR104 Male and Female Adapter Cables?
The UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable ends in nine pins, while the female version ends in nine holes. Everything else matches: PL2303 chip, 1.5m length, USB-A plug, shielding and the KSh 1,600 price at Mascom International. The male cable plugs into socket-type ports on modems, UPS cards, console leads and many industrial controllers. The female cable slides over pin-type ports on printers, scales and tills. Pick the male cable for socket ports; pick the female cable for pin ports.
Can I use the UGREEN CR104 Male Adapter Cable on site during a KPLC power cut?
The UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable takes its power from the laptop's USB port, so it keeps working on battery during a KPLC outage. That suits engineers at base station cabinets, borehole pump controllers and solar inverter sites where mains supply is unreliable. Your laptop battery sets the limit, not the cable. Charge fully before heading to a site in Machakos or Kajiado, and carry a power bank that can top up a laptop over USB-C.
Does the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable work with a MacBook?
The UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable supports macOS 10.6 and later, according to UGREEN. Because the plug is USB-A, a newer MacBook with only USB-C ports needs a small USB-C to USB-A adapter, sold separately at Mascom International. Once connected, the cable appears as a serial device that the Terminal app or a tool such as CoolTerm can open. Driver behaviour on the latest macOS releases can vary, so bring your MacBook in and we test it first.
How do I find which COM port the UGREEN CR104 male cable is using?
On Windows, open Device Manager and look under Ports (COM and LPT) for a Prolific entry, where the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable shows its COM number. Enter that number in your terminal program or device software. If the port shows a warning sign, install the PL2303 driver described in the included manual. UGREEN officially lists Windows 8.1, 8, 7, Vista, XP and 2000, so test on Windows 10 or 11 before a critical job.
Can the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable program a PLC or industrial controller?
The UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable connects to PLCs, motor drives and HMIs that use a female DB9 RS-232 socket. Maintenance teams in Industrial Area, Thika and Athi River use cables like this to back up and reload controller programs. Two checks matter: the device must speak RS-232 rather than RS-485, and its vendor software must accept a USB serial adapter. If both hold, the 1.5m lead lets your laptop rest safely away from moving machinery.
Who should buy the UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable, and who should skip it?
The UGREEN CR104 USB to DB9 RS-232 Male Adapter Cable suits network engineers, ISP installers, UPS technicians and PLC maintenance staff working with socket-type serial ports. It also suits developers who test embedded boards from a laptop. Skip it if the device you need to reach has nine exposed pins, because the female UGREEN CR104 fits there. Skip it as well for RS-485 or TTL serial equipment, which needs a different adapter, and for newer gear that offers a USB console port.
Technical Specifications
Core Function and Performance
- USB to RS-232 conversion — turns a USB port into a classic serial port for console access and data download.
- Prolific PL2303 chip — a familiar serial chip that most technicians and terminal programs already recognise.
- Speed up to 1Mbps — more headroom than the 9,600 baud a typical router console uses.
- DB9 male connector — nine exposed pins that push into a female serial socket on routers, modems or controllers.
- Shows up as a standard COM port — PuTTY, Tera Term and vendor setup tools treat it like a built-in port.
- 1.5m lead — lets you rest the laptop on a rack shelf or bench while the plug reaches the device.
Compatibility
- UGREEN lists Windows 8.1, 8, 7, Vista, XP and 2000 — fits the older workshop PCs common in plant rooms.
- macOS 10.6 and later supported — Mac-based network engineers can open device consoles through Terminal or CoolTerm.
- Linux supported — the PL2303 driver ships with most Linux kernels, so it typically works with no extra install.
- Windows 10 and 11 not on the official list — confirm with your own laptop at our counter before a critical job.
- USB-A plug — fits full-size USB 2.0 and USB 3.0 ports; USB-C laptops need a small adapter.
- Pairs with RJ45-to-DB9 console leads — reaches Cisco-style console ports on routers, switches and firewalls.
Build and Durability
- Tinned copper wire — resists the slow corrosion that degrades plain copper in humid plant rooms and coastal towns.
- Foil shield around the wires — cuts electrical noise from nearby power cables and variable speed drives.
- Braided mesh outer shield — a second barrier for stable sessions next to motors, generators and switchgear.
- Gold-plated plugs — hold a clean electrical contact after hundreds of insertions in and out of devices.
- Black cable jacket — stays presentable after months coiled in a field engineer's toolbag.
Inclusions and Support
- Genuine UGREEN cable — known chip and build, unlike the anonymous serial leads sold at many street stalls.
- User manual in the box — walks through driver installation and finding the assigned COM port.
- Console leads, null modem adapters and USB-C adapters not included — available separately where needed.
- 6-month Mascom International warranty — manufacturing defects are handled at our Nairobi CBD service desk.
- Counter testing available — we connect it to your laptop and confirm a working COM port before you pay.
