PT is packaged in 20 pins SO and capable of controlling 32 functions and 3 double keys. PT, on the other hand, is housed in 24 pins SO and capable of controlling 64 function keys and 3 double keys.
The inverse code of the data code is also sent simultaneously. The following diagram shows this one frame construction. The leader codes consist of a 9 ms carrier waveform followed by a 4. It is used as the leader for the following code. Thus, when reception is configured by a microcomputer, the time processes can be managed efficiently. Each code consists of 8 bits, and simultaneous transmission of the inverse code allows configuration of a system with an extremely low error rate.
Double Key Operation is possible for only Key No. Thus, only the following key combinations may be used for the double key operation: 1. Key Nos. Two key inputs are regarded as being pressed simultaneously when the time interval between these two key entries is less than 36 ms.
When a key is pressed, the custom and data codes are read. When the key is kept depressed during this 36 ms, one transmission is outputted. If the key is depressed for more than ms, then the only the leader code is transmitted continuously. The following table shows the Key Data corresponding to the double keys pressed. Also refer to the Key Input Section. The Lead Free mark is put in front of the date code. Dimensions In Millimeter Nom. Mold Flash, protrusion or gate urrs shall not exceed 0.
