However, while device-to-host transmission reads bits on falling Clock edges, transmission in the other direction reads bits on rising edges.

The device then generates a Clock signal while the host outputs a frame of bits on the Data line, one bit per Clock pulse, similar to what the attached device would do to transmit in the other direction. To send a byte of data back to the device, the host pulls Clock low, waits briefly, pulls Data low and releases the Clock line again. This mode of operation is still an option on the IBM AT and PS/2 keyboard port.)

The keyboard could not be commanded to retransmit a keyboard scan code after it had been sent, since there was no reverse data channel to carry commands to the keyboard, so the only way to avoid losing scan codes when the computer was too busy to receive them was to inhibit the keyboard from sending them until the computer was ready.

(For the IBM PC keyboard port, this was the only normal use of signalling from the computer to the keyboard.

(So far, all of this is the same as the unidirectional communication protocol of the IBM PC keyboard port, though the serial frame formats differ.) The host can use this state of the interface simply to inhibit the device from transmitting when the host is not ready to receive.

When the host pulls Clock low, the device must immediately stop transmitting and release Clock and Data to both float high. The host can interrupt the device by pulling Clock low while the device is transmitting the device can detect this by Clock staying low when the device releases it to go high as the device-generated clock signal toggles.

The host controls the direction of communication using the Clock line when the host pulls it low, communication from the attached device is inhibited. To transmit a byte, the device simply outputs a serial frame of data (including 8 bits of data and a parity bit) on the Data line serially as it toggles the Clock line once for each bit. Normally, the transmission is from the device to the host.

These are single-ended signals driven by open-collector drivers at each end. The interface has two main signal lines, Data and Clock. The bidirectional IBM AT and PS/2 keyboard interface is a development of the unidirectional IBM PC keyboard interface, using the same signal lines but adding capability to send data back to the keyboard from the computer this explains the asymmetry. The channel is slightly asymmetrical: it favors transmission from the input device to the computer, which is the majority case. )Д®ach port implements a bidirectional synchronous serial channel. (That is, keyboard drivers are written to use the first port, and mouse drivers are written to use the second port. However, unlike the otherwise similar Apple Desktop Bus connector used by Apple, a given system's keyboard and mouse port may not be interchangeable since the two devices use different sets of commands and the device drivers generally are hard-coded to communicate with each device at the address of the port that is conventionally assigned to that device. The PS/2 platform introduced a second port with the same design as the keyboard port for use to connect a mouse thus the PS/2-style keyboard and mouse interfaces are electrically similar and employ the same communication protocol. The PS/2 keyboard port is electrically and logically identical to the IBM AT keyboard port, differing only in the type of electrical connector used. The PS/2 mouse connector generally replaced the older DE-9 RS-232 'serial mouse' connector, while the PS/2 keyboard connector replaced the larger 5-pin/180В° DIN connector used in the IBM PC/AT design.

#Usb to ps2 converter for mouse series#

Its name comes from the IBM Personal System/2 series of personal computers, with which it was introduced in 1987. The PS/2 port is a 6-pin mini-DIN connector used for connecting keyboards and mice to a PC compatible computer system.

^ Sometimes, keyboard Clock for splitter cable.

^ Sometimes, keyboard Data for splitter cable.

^ Keyboard and mouse ports may be combined into a single port which can be used to connect both by splitter cable.
