October 3, 2024 - Serial communication devices make ... their cabled connections. They are commonly designated as DB-9 or DB-25 with the number used to differentiate between the pin counts. Various manufacturers’ names may replace the DB in the specifications. The plugs contain sockets and pins, with each pin numbered and labeled. A serial pinout diagram is presented ...

Normally the RS232 port is used by touch-panel controllers and similar devices. However, Wireless Designer can connect to a receiver frame over a PC's RS232 port as well. Use a cable wired as shown in the diagrams below.

Note that the same connector is ... and for cable mounting, in the latter case with the addition of a plastic or metal hood. Modern computers ship with both Com1 and Com2 in this style, usually assembled to the motherboard as part of the ATX format. Older machines use a 25 pin D shaped connector for Com2, the secondary serial port. The pins are numbered left to right across the first row, and then the same on the second row, as per the diagram ...

January 6, 2026 - A serial cable diagram illustrates the pinout of the connectors used (most commonly DB9 or DB25) and maps out the connections between the transmitting (TX) and receiving (RX) lines, along with handshake and ground lines.

Reliable, proven remote monitoring, alarms, and controls for industrial processes and conditions that are easier to use than traditional SCADA.

May 24, 2021 - These diagrams show the male (grey background) and female (black background) pin numbering for DB9 and DB25 sub-miniature connectors. Generally Pin 1 is marked on the front of the connector right next to the pin – though you may need a magnifying glass to read it. Some manufacturers mark each pin number on the plastic housing at the rear of the connector. The male connector has the pins sticking out! ...

All the diagrams below define the interface from the DTE perspective. An RS232 interface has a female and male connector, the male connector has the bits sticking out!! The terms Data Carrier Detect (DCD) and Received Line Signal Detect (RLSD) are one and the same. We use DCD throughout 'cos we think it's more common. Like most folks we use the term DB9 which is widely - but erroneously - used to describe a 9-pin serial ...
