1 Specifications

> 1.1 Communication Protocol

> The AGB dedicated protocol utilizes an RZ modulation method.
> Time is divided into fixed intervals, and the presence or absence of optical input during those intervals distinguishes signals.
> A general schematic is shown below:

> The 1bit signal width changes depending on the data communication speed.
> 1bit signal width (µ sec) = 1000 ÷ data transfer rate (kbps).

> 1.2 Communication Speed

> The data communication speed varies widely, depending on the ROM /RAM operating versions.
> Additionally, when using this version operation in ROM, the communication speed varies depending on the ROM access wait cycles.

> ROM version: Approximately (or up to) ~ 47kbps
> CPU internal RAM version: Approximately 104.2kbps

> ROM Version

> ROM Wait Cycles | Communication speed [Arguments of irSendConnect, irRecvConnect]
> 4 - 2 | 40kbps [IR_40kbps_RATE]
> 3 - 1 | 47kbps [IR_47kbps_RATE]
> Other | Not defined (Contact support@noa.com for support if needed.)

> Version operating in CPU internal RAM

> Communication speed [Arguments of irSendConnect, irRecvConnect]
> 104.2kbps [IR_104kbps_RATE]
