{TOC} '''UNDER DEVELOPMENT''' This keyboard plug in [Open interface III] with [IP switch|IP Switch with ESP32-GATEWAY] realize low latency (<4ms with ethernet switch) IP control 16 output relays in two bank. BankA switch each each independet output on/off. BankB switch always one output from eight available. BankA is upper line switch buttons, BankB bottom line. !

How ID are use on actual selected band, determines table in firmware {{ // BAND TO REMOTE SWITCH ID int BandToRemoteSwitchID[12] = { /* IP Switch ID 0-7 */ 0, // band 0 (no data) 0, // Band #1 [160m] 0, // Band #2 [80m] 0, // Band #3 [40m] 0, // Band #4 [30m] 0, // Band #5 [20m] 0, // Band #6 [17m] 0, // Band #7 [15m] 0, // Band #8 [12m] 0, // Band #9 [10m] 0, // Band #10 [6m] 0, // Band #11 [2m] }; }} By default using on all bands IP switch with ID 0. !!BankC - rotary encoder Open Interface III use for IP switching from rotary encoder (BankC) independents hardware. ID calculate automaticaly increase eight from ID for ACC keyboard. This means that in previous situation on all bands rotary encoder (menu 20) use IP switch with ID 8. Range rotary encoder is up to 16 outputs, wich may be limited for each band separately in table {{ int IpSwBankCrange[8]= { /* number of IP switch bank C position 2-16 range */ 16, // ID 8 8, // ID 9 8, // ID A 8, // ID B 8, // ID C 8, // ID D 8, // ID E 15, // ID F }; }}
