RS232 / RS485 / RS422 Data Repeaters
The SerialComm REP-232-3P is a pair of high quality, high performance. industrial-grade port powered 3-wire RS232 data line extenders with included DB9 or terminal block. This converter pair features optical isolation in a 9 pin format and is enclosed in a resilient housings. The pair of REP-232-3P will extend the distance of the RS232 RX and TX data lines up to 4000 feet (1.2km) while providing voltage surge protection. The repeaters are 2500V opto-isolated to protect from lightning strikes and voltage surges. This product will also handle grounding issues and noise conditions as well. Our converters are protected by a 5 year warranty and 30 day money back guarantee. 300 to 115.2K Baud Operation. Price: $42.95 - PAIR
The SerialComm REP-232-7P is a pair of high quality, high performance, industrial-grade port powered 7-wire RS232 data and handshake line extenders with included db9 or terminal block. The pair of REP-232-7P will extend the distance of any RS232 RX and TX data lines as well as the CTS, RTS, DTR and DSR handshake lines up to 4000 feet (1.2km). The repeaters are 2500V opto-isolated to protect from lightning strikes and voltage surges. This product will also handle grounding issues and noise conditions as well. Our converters are protected by a 5 year warranty and 30 day money back guarantee. 300 to 115.2K Baud Operation. Price: $54.95 - PAIR
13 Important Factors in Choosing the Best RS232 Exteneder
1. How to choose the right signal processor?
When it comes to RS232 extenders, the signal conversion processor used is an important factor. Our converters use signal processors by Toshiba Semiconductor. They are of the highest quality and very reliable due to their signal conversion characteristics. These processors have true to standard RS232C. The wire interface also produces very strong 1.5V balanced signals making communication very reliable and flawless. These processors also feature autosensing auto-turnaround eliminating the need for software drivers or flow control.
2. Why do terminal blocks make installation simple?
3. Why RS232 extenders are better solutions then RS485 and RS422?
Although RS485 and RS422 converters can be used to extend the distance of the RS232 the RS232 extenders are a better solution because they are more economical. The REP-232-3P and REP-232-7P are isolated and full duplex and are much more cost effective then the RS485 and RS422 converters.
4. What is the difference between the REP-232-3P and REP-232-7P?
The REP-232-3P is a RS232 data line extender. It extends the distance of the RX and TX data lines. The REP-232-7P is RS232 data and handshake signals extender. It extends the data lines RX and TX as well as the handshake lines CTS, RTS, DTR and DSR.
5. At what distance can the RS232 extender communicate reliably?
The RS232 port normally has a distance limitation of 16 ft (3 m). The RS232 extender converter pair will reliably extend the distance of the RS232 signal up to 4000 ft (1.2 km). If you need to extend the distance further then that we would recommend using the RS232 to fiber optic converter which can extend the distance up to 12.5 miles (20 km).
6. Why are the RS232 extenders sold in pairs?
The REP-232-3P and REP-232-7P RS232 extenders are sold in pairs because they use a proprietary 4 wire interconnection protocol. They need to operate in pairs - one for each end.
7. Why do our products feature auto-turnaround?
Our RS232 distance extenders come with the built-in autosensing auto-turnaround. The start bit of the data is automatically sensed thus changing the direction of the data flow avoiding the possibility of data collisions. This is handled automatically by the signal processor and eliminates the requirement of using software drivers or flow control.
8. Why our products come with ESD and surge protection?
Electrostatic or ESD static protection and surge suppression protection is a standard feature on all RS232 extender products. Our products come with 15KV ESD protection and 600W/sec burst surge protection. These features was tested in the factory lab and during CE and FCC testing by an independent testing facility.
9. How is quality engineering & standardized product testing important?
Quality engineering and standardized product testing is an important factor to ensure reliability in our RS232 extender converter products. Serialcomm products have an industry proven high reliability rate over 99% and are CE, FCC and RoHS certified. And because of this, we offer a 5 year replacement warranty on our products. As part of our commitment to providing the highest quality and reliable products some of the tests performed on our products include temperature, vibration, free fall, shock, EMI emissions and EMI radiation susceptibility and other environmental tests.
10. Why is reliable brand important?
Serialcomm is an industry proven reliable brand you can trust. Serialcomm has sold to many of the high tech leaders both in the U.S. and abroad. We back all our products with a 30 day money back guarantee and 5 year replacement warranty and we do not charge a restocking fee if product is returned. Serialcomm products are designed with proven engineering techniques with an established quality assurance program. Some companies sell converters from a multitude of Chinese manufactures with all different levels of quality and they do not now how they are designed or tested. Serialcomm offer the highest quality products at wholesale prices.
11. Importance of 12/7 telephone and live chat support?
We offer 24/7 telephone and live chat support as well as email support. Some companies only offer email support. Serialcomm is dedicated to its products and customer support. If you need technical help or have a question you want to be assured you can talk to an engineer/customer/sales support at your schedule without having to wait for an email response that can take days.
12. Why we do not charge restocking fees?
A restocking fee is a handling charge that some companies charge when product is returned. Customers should be careful of companies that charge as high as a 20% restocking fee with the only customer disclosure in their Terms and Conditions statement. At Serialcomm we give you 30 days to decide whether you want to return the product at a full refund without any penalties or additional fees.
13. How free shipping and guaranteed express important?
We offer free shipping on all our products. This is a major savings for our customers. We do not offer a very low price and then add extra charges on the shipping to make up for the low price. We also offer optional expedited services by FEDEX, UPS and DHL. We offer FEDEX express services up to 7:30 PM EST or 4:30 PST which is the most flexible schedule on the market. If you decide to use your courier account we do not add any additional handling charges. We pride ourselves in our track record of getting packages to FEDEX on time.
