(COSW). Alpha Tech Brave SlimDP

2.6 Code relay (COSW)

For the switch (relay) is available function code relay (COSW

CodeSwitch). It serves primarily to secure transmission of information by switching the electric lock. When using this function is not possible connecting or disconnecting the voltage at the terminals to lock this lock activated.

Activation is performed only when positive result compared serial information transmitted between Brave and the board code relay

Brave is set in several codes to activate the relay code.

Relay can be activated codes for one or two impulses can differentiate activated from the phone (DTMF) or from keys

(keyboard). The last option is the activation code in another mode switch than the lock.

The code information is 8 bits, but the code is 4 bits with security 4 bits which is total of 8 bits. Practically, this is performed so that after activation the switch is first transmits the serial code, and if they agree, so code relay connects the electric lock.

The code relays can be connected in parallel to increase the number of switches, but can never combine connections electric lock and the code relay parallel!
