What is a de 9 serial port?
A serial port on a PC is a male 9-pin connector (DE-9 D-sub). Early PCs had two 9-pin connectors or one 9-pin and one 25-pin (DB-25).
What is a 9 pin cable used for?
The DB9 connector is mainly used in serial ports, allowing asynchronous data transmission according to the RS-232 standard (RS-232C). Note that there are DB9-DB25 adapters that easily convert a DB9 socket to DB25 and vice versa.
Is RS 232C same as VGA?
But I’m curious because you say that the connectors look “exactly like VGA ports.” Usually RS232 utilizes a DB9 (DE9 for the educated and/or purist) with is the same size as a VGA (HD15) but has only 9 pins in two rows instead of 15 pins in three rows.
Is DB9 the same as RS-232?
DB9, for example, is a 9 pin connector for a serial cable. You can see one here. RS-232, on the other hand, refers to the standard itself. RS-232 (sometimes called EIA-232) describes how systems can communicate between each other using a serial cable.
Is DB9 a RS232?
Below is the pinout of a typical standard male 9-pin RS232 connector, this connector type is also referred to as a DB9 connector. A computer’s serial COM port (DTE) is usually a male port as shown below, and any peripheral devices you connect to this port usually has a female connector (DCE).
Are DB9 cables still used?
DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also they are used on DB9 cable assemblies for data connectivity. Today, the DB9 has mostly been replaced by more modern interfaces such as USB, PS/2, Firewire, and others.
Can VGA be used as serial?
No it will not work with a VGA monitor. If it is specifically marked as RS-232 (or with a string of one’s and zero’s), then it is a serial port for things like serial mice.
What is the difference between VGA and serial port?
The closest thing in a VGA port is the I2 C lines for reading the monitor’s specs when you plug it in. Serial ports are 9 pin and vga is 15, so no.
What is DB9 serial?
DB9 connectors are designed to work with the EIA/TIA 232 serial interface standard, which determined the function of all nine pins as a standard, so that multiple companies could design them into their products. DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc.
Can wiring DB9?
It covers wiring for the common DB9 plug and socket often used with CAN bus test equipment….CAN Bus 9-pin D-Sub (DB9) Pinout Table.

| 1 | Reserved |
| 2 | CAN_L bus line dominant low (a.k.a. CAN low or CAN-) |
| 3 | Optional CAN ground |
| 4 | Reserved |
What does DB mean in DB9?
So what exactly does DB stand for? The DB moniker used on multiple Aston Martin models actually stands for David Brown, who purchased Aston Martin in 1947.
