RECEIVING SIGNAL INPUT CIRCUIT Signal received by the light receiving element is sent through the Pre-Amp to the detector, when a 38 kHz carrier wave is eliminated and the signal enters a REMIN PIN of the receiving signal input circuit. The receiving signal input circuit (REMIN) has a built-in Schmitt trigger for shaping receiving signal waveforms to eliminate rounding. Figure 5. 4. RECEIVING SIGNAL CHECK The receiving signal check is to check the 2-cycle transmitting signal sent from the transmitter to check whether it is a normal signal or not. Figure 6. The first data is stored in the 12-bit data register. Then, when the second data is entered, the previous data is pushed out from the data register one by one. The pushed out data and incoming data are checked to see if they are same. If any errors are caused during the 12-bit receiving data check, the system is reset at that time. And when all receiv- ing data are same, output is raised from L level to H level. The status of receiving data, register clock and check pulse are shown below. Register clock is provided in the data center by taking frequency margins of the transmitter and the receiver into consideration. AMP DET REMIN PH302B

CODE BIT COMPARISON In order to prevent interference with other machines and apparatuses, C1, C2 and C3 code bits are provided for checking whether or not the transmitter codes agree to the receiver codes. Only when both codes agree, the internal latch pulse is generated to latch receiving data, and output is raised from “L” level to “H” level. If both codes do not agree, latch pulse is not generated and output remains at “L” level. Code bits used differ depending on receiver as shown below: CODE BIT S5G9801X01C2, ⋅⋅⋅⋅⋅⋅ C3 is used. S5G9803X01C1, ⋅⋅⋅⋅⋅⋅ C2 is used. * CODE BIT “ 0 ” , “ 0 ” cannot be used.

S5G9803X01 is able to use all keys, but S5G9801X01 can use KEY1 - 5 and KEY 7 - A only for 10 commands. CONT : Continuous, SING : Single, TOGG : Toggle NOTE : S5G9802X01 has 18 function keys, and total 75 commands can be transmitted: 63 commands by the continuous keys of multiple keying is possible and 12 commands by the single-shot keys.

The combination of code bits of S5G9802X01 and S5G9801X01 is shown in Table 1. To make the code bit to 1 on S5G9802X01, connect diodes to the CCI terminal from ST1 - ST3 terminals. To set Code Bit at 0, open the circuit. S5G9801X01 has CODE2 and CODE3 code terminals. Code bit of C1 has been pulled up in IC and C1 is always kept at 1 status. Therefore, on transmitter S5G9802X01, it is necessary to keep C1 code bit at 1.
