The typical oscillator with various resistor values is shown below for both PT and PT Details are as follows. Their waveforms are shown in the diagram below.

To get the 38KHz carrier frequency at the data output, the oscillator frequency must be 76KHz. After two consecutive valid transmissions, PT 1 drives the data pins according to the data bits received, and 2 raises VT to high voltage high state. The timings are shown in the following diagram.

The latch type PTLx activates the data out during transmission and this data is sustained in the memory until another data is inputted or entered.

A momentary type PTMx , on the other hand, activates the data out only during transmission. In the momentary type, the data does not remain in the memory after the transmission is completed.

It then searches for signals. If there is no signal received, it remains in the Stand-By Mode; otherwise, the address bits received are compared with the address configuration of the pins. The VT goes high signifying the validation of transmission only when there are two 2 continuous frames that contain matched address bits; otherwise, VT will not be activated and the Stand-By Mode remains active.

Then, the Address Bits are again checked.

Two continuous mismatches of the address bits would disable the VT and make the Stand-By Mode active; otherwise, the address bits are continuously checked. If there is no signal received, it remains in the Stand-By Mode; otherwise, the address bits are compared with the address configuration of the pins.

Whenever the Address Bits in a Frame match with that of the Address Configuration of the Pin, the data bits are stored into the memory. Also, when this IC finds two 2 continuous and identical data having the same address bits, the data output s is activated and the VT is enabled. The VT is disabled when there are 2 continuous mismatched addresses. For the momentary type, the data output is reset; while for the latch type, the data output is sustained.

One bit waveform consists of 2 pulse cycles. Each pulse cycle has 16 oscillating time periods.

Bit 1 is only available for Address Bit. Synchronous Sync. The 12 AD bits are interpreted as either address or data bits depending on the PT version used. For the PT to decode correctly the waveform that was received, the oscillator frequency of PT must be 2. It is a good practice to center the PT oscillator frequency in this window to gain best window margin at both sides.

PTM4 Description

The typical oscillator with various resistor values is shown below for both PT and PT Details are as follows. Their waveforms are shown in the diagram below. To get the 38KHz carrier frequency at the data output, the oscillator frequency must be 76KHz. After two consecutive valid transmissions, PT 1 drives the data pins according to the data bits received, and 2 raises VT to high voltage high state. The timings are shown in the following diagram.

The latch type PTLx activates the data out during transmission and this data is sustained in the memory until another data is inputted or entered. A momentary type PTMx , on the other hand, activates the data out only during transmission. In the momentary type, the data does not remain in the memory after the transmission is completed. It then searches for signals.

If there is no signal received, it remains in the Stand-By Mode; otherwise, the address bits received are compared with the address configuration of the pins.

The VT goes high signifying the validation of transmission only when there are two 2 continuous frames that contain matched address bits; otherwise, VT will not be activated and the Stand-By Mode remains active. Then, the Address Bits are again checked.

Two continuous mismatches of the address bits would disable the VT and make the Stand-By Mode active; otherwise, the address bits are continuously checked. If there is no signal received, it remains in the Stand-By Mode; otherwise, the address bits are compared with the address configuration of the pins. Whenever the Address Bits in a Frame match with that of the Address Configuration of the Pin, the data bits are stored into the memory.

Also, when this IC finds two 2 continuous and identical data having the same address bits, the data output s is activated and the VT is enabled.Please enter a number less than or equal to 7.

If there is no signal received, it remains in the Stand-By Mode; otherwise, the address bits are compared with the address configuration of the pins. Also, when this IC finds two 2 continuous and identical data having the same address bits, the data output s is activated and the VT is enabled.

Transmitter works with 5V to 12V DC. The Waveform is decoded into code word that contains the address, data and sync bits.

The PT must match the addresses in two pulse trains to its own address, to accept. All outputs are TTL level can be interface with other circuits or relay board. Also, when this IC finds two 2 continuous and identical data having the same address bits, the data output s is activated and the VT is enabled.
