4.0 Visual (YELLOW LED) and Audible Signals
3.4.4 Return to default settings
By using menu 9 the factory-set default settings are entered into the MONO-S memory.
Default settings are: 1. Default functioning mode activated (all codes sent to the host)
2. Maximum code length = 8 digits
3.4.5 Data output from the MONO-S in DATA/CLOCK format
The complete data message consists of a start character (B hex) then 8 data characters (4 bits + odd
parity) followed by an end character (F hex) and a LRC checksum character (4 bits XOR over all bits +
odd parity on these 4 bits).
Start sentinel 8 digits code End sentinel LRC (XOR)
1101P xxxxP xxxxP xxxxP xxxxP xxxxP xxxxP xxxxP xxxxP 1111P yyyyP
Example 0 0 0 0 0 5 2 8
11010 00001 00001 00001 00001 00001 10101 01000 00010 11111 11010
Note: Before the start sentinel signal, MONO-S sends first a zero bit to indicate the presence of a code
and allows the host to synchronize with the incoming data bits.
:
1 digit = 1 character = 5 bits.
:
P = odd parity calculated over the 4 leading bits of each digit.
:
XOR = logical operation calculated over the entire 10 digits, excluding the parity bit.
:
Characters are encoded with the least significant bit first
3.5 CODIX format
There is no further programming menu for the MONO-S with CODIX format.
In the programming mode, when entered into any of the sub-menus, the bi-colour LED turns green.
4.1 MONO-S CODIX version
- Beeps and flashes for a period of 3 seconds (beep…beep…) indicates an operating error.
- Beeps and flashes for a period of 30 seconds (beep…beep…) indicates 8 consecutive incorrect codes.
- 5 intermittent signals (beep-beep-beep + Yellow LED blinking) indicates a communication problem
on the bus for which one should check the connections to the CODIX bus.
- Once a code is entered and the key “A” is pressed the MONO-S emits an audible (beep) and visual
(Yellow LED) signal. If the entered code is correct, a second confirmatory beep will be heard.
- If the host does not receive the sent data verify that the data line (DATA) is not broken.
4.2 MONO-S WIEGAND and DATA/CLOCK versions
- Beeps and flashes for a period of 3 seconds (beep…beep…) indicate an operating error.
- Once a code is entered and the key “A” is pressed the MONO-S emits an audible (beep) and visual
(the Yellow LED) signal.
- If the host does not receive the sent data verify that the 2 data lines are not broken.
