Decoding output level | High and low level | |
Encoder oscillation resistance choice | PT2262 encoder 2.2M to 4.7M eV1527 encoder 270K to 430K | PT2262 encoder 4.7M eV1527 encoder 330K |
Static-free ESD sensibility | 1ESD(2000V) | HBM mode: according to MIL-STD-883C standard, use method: Method 3015. Need to keep and use in static-free situation |
Operation:
1. Press the button of ZW20-J for one time, and learning indicator light once, in press a button on the remote control of arbitrary, study indicating lamp glimmer four times, says learn successful, right now ZW20-J decoding the level of output feet locked state. (similar to PT2272-M4)
2. Press the button of ZW20-J for 2 times , and at the same time learning indicator twice, in the press a button on the remote control of arbitrary, study indicating lamp glimmer four times, says learn successful, right now ZW20-J decoding output level for interlock feet state. (similar to PT2272-BMD at l1-l4)
3. Press the button of ZW20-J for 2 times, at the same time, learning indicator light is three times, in the press a button on the remote control of arbitrary, study indicating lamp glimmer four times, says learn successful, right now ZW20-J decoding output level for the feet locked state. (similar to SC2272-T4)
4. Press the button of ZW20-J for 2 times, at the same time, learning indicator light is four times, click on the remote control in any key, learning indicator light four flashes, say learning success, at this time ZW20-J decoding output level for the point start feet state.
5. Hold learning button and hold it down, and at the same time learning lamp light 10 seconds long put out, says clear success, this time can loosen the learning buttons.
Pin describe
pin number | Pin name | Pin describe |
1 | ANT | RF signal input feet, the pin to access the antenna. |
| 2 | GND | Sub-pin power supply negative, also can meet the shielded wire high frequency landlines. |
3 | K1 | Study choice function keys, low level effective (can connect a light touch the switch to the power negative) |
4 | VDD | Dc power positive input the pin |
5 | VT | D1- D4 output state instructions (initial for low level, decoding, successful output high) |
6 | VSS | Connect power negative |
7/8/ 9/10 | D1/D2/D3/D4 | Decoding success, data output corresponding feet (initial for low level, decoding, successful output high) |
Decoding the output pin and encoding chip data corresponding relations between the feet
