When using multi-button transmitters it is recommended to use the ‘C4+’ protocol.
Within this protocol, only one radio receiver interface connected as reader No.1 is needed to control up to 4 doors: the interface sends to the controller, in addition to the card code, the code of the button used, from 1 to 4 (when the emitter get such buttons). The controller then proceeds the information as if it came from reader 1 to 4.
Connect the interface RF as follows :
Interface RF: |
IC2000/4000 |
+ (12Vdc) |
J7/12Vdc |
- (0v) |
J7/0v. |
S (Signal) |
J1/CLK1 |
Notes:
- To use the C4+ interface, position and the TPL Dip switches JP4/6,7,8 in ‘on, off, on’ position and DS2 to off, off, off, off
- The controller firmware version (Eprom or Flash) must be 03/04/02 or latest.
- Type of cable : 3 core shielded wire, 22 AWG. Max. length: 200m
- Refer to the Interface RF manufacturer manual for details on setting the radio receiver protocol to C4+.
