How to Install Black Box RS232 Passive Splitter Rackmount Chassis - 2U, RJ45
- Plan and prepare: Assess your serial topology to determine how many devices and ports will connect through the chassis. Confirm that you will host up to 16 RS232 RJ45 passive splitters and map which devices each splitter will serve to ensure a smooth installation.
- Verify rack space: Choose a suitable location in a standard 19-inch rack with adequate clearance for cabling, ventilation, and future expansion. Confirm that the mounting rails and hardware are compatible with your rack.
- Mount the chassis: Slide the 2U enclosure into the chosen rack space and align with the mounting holes. Secure the chassis firmly using the appropriate rack screws, ensuring it sits level and does not flex under cable loads. A stable base minimizes wear on connectors over time.
- Connect RS232 RJ45 passive splitters: Attach the RS232 RJ45 passive splitters to the modem side and to the serial devices as dictated by your network diagram. Because these splitters are passive, no external power source is required for distribution, but ensure RJ45 connectors are fully seated to prevent intermittent connections.
- Organize and label: Route cables with ties or straps to prevent tangling and to maintain airflow. Label each port and splitter clearly to simplify future maintenance and troubleshooting, especially in high-density installations where quick identification matters.
- Test and validate: Power on the modem and the connected devices, then verify serial communication across all channels. Check baud rates, parity, stop bits, and data framing for consistency. Validate that each terminal receives the expected signals without distortion or loss.
Frequently asked questions
- Q: What exactly is a RS232 passive splitter? A: A RS232 passive splitter is a non-powered device that enables multiple serial devices to share a single modem by duplicating or branching the serial signal through passive circuitry, without altering data formats or speeds.
- Q: Do I need to power the splitter chassis? A: No. The chassis and the RS232 RJ45 passive splitters are designed as non-powered, passive devices, so no external power is required for operation.
- Q: How many terminals can share a modem using this chassis? A: The chassis is designed to hold 16 RS232 RJ45 passive splitters, allowing multiple terminals to share a single modem, depending on the splitter configuration and cable length.
- Q: Will this chassis affect data speeds or signal quality? A: The splitters are described as transparent to data formats and speeds, so the intention is to preserve baud rates and overall signal integrity when distributed to multiple devices.
- Q: Is the chassis compatible with all RJ45 RS232 splitter types? A: The design is intended for RS232 RJ45 passive splitters, but compatibility with specific port densities and connector configurations should be confirmed with the product documentation or manufacturer guidance.

What is better? The overachieving 6 or underachieving 8?
Format: Hardcover
First, let me say that I thought that this was an excellent book and would recommend it to anyone who is at all interested in the college admissions process. Second, I was surprised at how many of the reviewers seemed shocked--shocked!--that applicants got bonus points for coming from minority backgrounds. Was this some kind of revelation? However one thing that surprised me a little bit is how--even moving beyond race entirely--the more advantages you have had in life, the more disadvantageous it will be for your admissions process. For example, I was unaware that having successful parents would be, in essence, held against you on the theory that more would be expected of you. While other reviewers have (jokingly?) said that they would advise their white kids not to check the "Caucasian" box, I might advise my (still very young) kids to say that their parents have been unemployed their whole life.
I suppose that the main issue which this whole process really boils down to is the following: As a college applicant, is it more important to succeed in life relative to the world around you (i.e. relative to your classmates, to others of your race, to others of your geographical area, to your own parents' life and accomplishments, etc.) or is it more important to succeed absolutely and not on a relative scale. This book clearly informs us that the answer is the former and not the latter. Whether that should be the answer is another question.
For example, say that a student's entire life could be distilled into 2 numbers each on a sliding scale from 1-10. The first number is simply your academic performance (grades, SAT's, course load, etc.) The second number is your background (race, economic circumstances, gender, etc.) In the case of Wesleyan, it seems clear to me that they would rather have a student whose first number was, say, a 6 if his or her second was a 2 (take Mig for example in Steinberg's book) than a student whose first number was an 8 if the second number was a 9 or 10 (take Tiffany Wang for example). Whether that is the right approach is certainly a legitimate issue for discusion and I'm not saying that it's not.
I suppose that one of the things that would be interesting to know (even though one never really can know of course) is whether those numbers will change in the future. For example, if one were to know that Mig would always be a 6 and Tiffany would always be an 8, would that change the analysis as to which is the right approach? I suspect that part of the reason that a school like Wesleyan would favor the overachieving 6 over the underachieving 8 is due to the hope or expectation that those trends will continue in the future and that one day the 6 will actually be ahead of the 8. And maybe that's the way it works. Who knows.

You will find out how a selective private college evaluate and admit students
Format: Paperback
I'm a high school counselor and college advisor. Fifteen years ago when I started my college counseling position, I struggled to understand or explain to students and their parents how a selective private college evaluate and admit students. It was this book that helped me understand the essence of selective private college admissions. Compared to other dry theory books, this book tells the admissions practice as stories that are easy to read, understand, and associate with. I highly recommend this book to students, parents, and new counselors.

Who edited this mess?!?!?!?
Format: Kindle
This is a very interesting work of nonfiction. I found it intriguing and read it very quickly. I actually got invested in these students and their stories and their journey to get admitted to the college that was right for them. BUT, and this is a big but, this book is so poorly edited, it is disgraceful! If a person were reading this for research purposes, and it could be useful for just that, good luck to them. The dates are all over the place. At one point, the kids are being considered for the class of 2004, then it makes a reference to the current year as 2000, then it reverts back to 2004 for a long while, then it mentions how the kids--currently at their various chosen colleges--reacted to the events of 9/11/01. What the hell? It's very confusing. It makes it very difficult to keep things in context.

Abundant information but needs update
Format: Kindle
I struggled a little when try to decide how many star to give. It's an excellent book and very informative. It feels like I was not reading a college admission advisory book, which very often are dry and mechanical. It feels like reading stories of students and AOs, I got attached and involved emotionally, and really felt for them. But there were abundant information in the book, I was able to use the book to answer most my questions. If you need a list of YESs, Nos, Warnings..., then this is not the book for you. If you need to know what happens during admission process, then this is an excellent book for you. Based on the information in this book, I was able to extract my own conclusions.
The reason I hesitated if I should rate this book as a five stars book is how long ago it was written. A lot has changed. Many aspects stayed same, but many aspects changed. It will be misleading if this is the only guide book you are using. Wish everyone a great college application season.

An intimidating read
Format: Paperback
This is a scary book to read if you are anyone, but most especially a Parent of a college bound junior or senior. The writer, Jacques Steinberg, a NY Times Reporter writes beautifully and captures the college application process in an authentic way, without overdramatization. His style and sensibility reminds me of Jon Kraukeur. I was prinicipally struck by the heroic Sisyphean efforts of the admissions office and the immense gap between public school and private school admissions counseling at the high school level, a gap which is even greater today. This is also a very good description of Wesleyan University -- what it is not so good at, and this is no fault of the author who tries to make this point and the related one that follows , but the best approach for the applicant is to find a college where he and she can thrive and trust the process, the admissions folks are very dedicated to bringing in students who can add value and to whom they can add value -- more to the point when a good fit is made, all the effort and anxiety is well worthwhile to the school and the applicant. good luck and best wishes to all of you who are college bound.
