FAQ:
Q: What is rs-232d over RJ45?
A: UTP and FTP cables with RJ45 connectors became the de-facto standard in office cabling systems, and people started looking for ways to transmit RS232 signals over this cabling system. The RS-232D standard (more properly called EIA/TIA 561) was the official attempt for a standard to transmit RS232 over RJ45.
Q: What is the wiring scheme for a Yost RS232 to RJ45 adapter?
A: The wiring of a Yost RS232 to RJ45 adapter for a DCE is more or less a mirror of the DTE adapter wiring. The Yost standard defines the wiring scheme for both DB9 and DB25 connectors. Because DB9 connectors are rarely used on DCEs, there is only a picture of the larger version here.
Q: What is the best pinout for an RJ45 port?
A: The following pinout examples are based on an 8pin RJ45 connector and can be applied to all Speed RJ45 ports. For standard terminal operating at slow speeds or using software flow control. a simple 3-pin connection can be used.
Q: Why is the RS232 signal split in two lines?
A: The signal ground has been split in two lines to get a symmetric layout. Two common RS232 signals are missing on the RJ45 connector. The ring indicator RI is often not necessary because most modems also signal incoming rings with the text “RING” on the data lines.
