What devices use RS232?
Applications of RS232 Communication RS232 serial communication is used in old generation PCs for connecting the peripheral devices like mouse, printers, modem etc. Nowadays, RS232 is replaced by advanced USB. It is also used in PLC machines, CNC machines, and servo controllers because it is far cheaper.
What is RS232 used for?
An RS-232 serial port is most often used by repair technicians to perform diagnostics and service updates. It may also be used to control a device when connected to a computer running a home automation system or Custom Integrated Audio/Video (A/V) system, such as the CAV-M1000ES Multi-room A/V Distribution System.
How many devices can RS232 support?
RS-232 is the simplest of the two interfaces. It is used to connect two devices as illustrated below: That is, the transmitter of Device 1 is connected to the receiver of Device 2 and vice versa.
Are there different types of RS232?
The RS-232 specification defines two types of serial devices, DTE and DCE. DTE normally refers to the serial port on a PC or terminal, while DCE refers to a modem or other type of communications device.
How do I connect two devices to RS-232?
All you do is pass the wires between them male one end, female on the other, connecting pin X on the DTE to pin X on the DCE side. Provided, the DTE and DCE agree on transmission speed, you are done.
Can you have multiple devices on RS-232?
yes the drivers are push/pull types, however with one transistor on the send parts and one resistor on the receiving master it is possible as this way it only pulls the line down. if connecting more receivers you can go to max 5 as master can not give more power.
Can RS-232 be used for video?
Significantly in the AV industry, RS-232 does not transmit audio and video signals, but is used specifically for control of devices in an AV system; so source devices such as some BluRay players and digital media players, display devices such as televisions and projectors, as well as signal control products such as …
