Der horizontale Abstand zwischen den RS-232 Schnittstellen könnte 1-2 mm größer sein, damit auch Kabel mit guter Schirmung nebeneinander Platz haben Review: Product works great. Connections are stable when plugged into my computer. I've used a lot of other products that will disconnect if you bump the cable, but this one doesn't do that. Materials seem solid unlike a lot of others I've used. Also, works great with MAC-OSX and Iterm/terminal. I'm on version 10.11.2 and had no issues getting it up and running. ## Features - INDUSTRIAL STRENGTH: Built to withstand harsh environments, this 4 port USB to serial RS232 adapter has a rugged all-metal enclosure for added durability in industrial settings - COM RETENTION CAPABILITIES: For added convenience, this FTDI USB to DB9 RS232 hub features COM retention so COM port assignments are maintained during reboots - PLUG AND PLAY INSTALLATION: This DB9 serial converter is powered by an available USB port / cable so no external power adapter is required - INSTALLATION OPTIONS: This USB serial adapter has integrated wall mount brackets and included DIN Rail clips for versatile mounting options ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008U3OVHW | | Best Sellers Rank | #46,387 in Computers ( See Top 100 in Computers ) #118 in Serial Adapters | | Brand | StarTech | | Built-In Media | 1 - USB to RS-232 Serial Adapter | | Color | Black | | Compatible Devices | Amplifier, Cameras, GPS, Gaming Console, Laptop, MP3 Player, Monitor, PC, Speaker, Tablet | | Connector Type | USB Type B, DB-9 | | Customer Reviews | 4.6 4.6 out of 5 stars (290) | | External Testing Certification | CE, FCC, RoHS | | Finish | Metallic | | Global Trade Identification Number | 00065030848343, 00163120552115, 07337331815670 | | Input Voltage | 5 Volts | | Item Dimensions | 17.8 x 5.8 x 2.3 centimeters | | Item Weight | 0.66 Pounds | | Item Width | 2.3 Inches | | Manufacturer | StarTech.com | | Model Number | ICUSB2324I | | Nominal Power | 1.5 Watts | | Number of Items | 1 | | Number of Ports | 4 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | Industrial serial device control, connectivity in harsh environments | | UPC | 100177410876 044111289022 065030848343 014444662885 151903389768 761651742939 163120552115 650308483434 042111893744 395782981471 851975714061 031112398754 | | Unit Count | 1 Count | | Warranty Type | Limited | ## Product Details - **Colour:** Black - **Compatible devices:** Amplifier, Cameras, GPS, Gaming Console, Laptop, MP3 Player, Monitor, PC, Speaker, Tablet - **Connector type:** USB Type B, DB-9 - **Item dimensions L x W x H:** 17.8 x 5.8 x 2.3 centimeters - **Specific uses for product:** Industrial serial device control, connectivity in harsh environments ## Images ![Startech.Com 4 Port Usb To Serial Rs232 Adapter - Wall Mount - Din Rail - Com Port Retention - Ftdi Usb To Db9 Rs232 Hub (Icusb2324I),Black - Image 1](https://m.media-amazon.com/images/I/71d5VvmcKtL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Does this give "true" rs232 ~12v signals on pin 2 and 3 rather than just 5v? also it says "no power outlet required" but there is a plug?! what gives?** A: Technically the original spec has been modified many times. In 1981 when I first dealt with it, the values were 15 volts positive and negative. Thanks to the IBM PC that only had 12 volts positive and negative, many people mistakenly think that is the standard. Currently the standard will accept positive and negative 25 volts, with any signal above 3 volts or below negative 3 volts being valid (that value has not changed). I know and understand what you are asking for, a non-TTL signal level. I am ordering this myself and will let you know. **Q: Is this taa compliant?** A: The country of origin is Taiwan. The company does has not posted a TAA cert. It is however, RoHS compliant and FFC approved. You may contact Star Tech for further info at Tel: (800)265-1844. As a product, I recommend it very highly. Sorry I cannot answer more directly. **Q: Can i assign coms? for example ch1 = com1 ... ch16 = com16** A: Yes, you will be able to assign / change COM ports with the ICUSB23216FD. The ICUSB23216FD also supports COM port retention, which retains the assigned serial COM port values. Atha, StarTech.com Support **Q: Doesn't seem to come with the power cable. Is there a name for that type of power cable?** A: ICUSB2322I pulls power from the USB host and does not require a power adapter. If the preference is to use a power adapter, any 5V, 0.5A (or higher) with an M barrel connector will work.
