Sound Control Protocol for SpeechLine Digital Wireless

SSC Developer‘s guide for SpeechLine Digital Wireless | 105/109
SSC Method List (CHG 2N/CHG 4N)
14.54 /bays/state
Parameter type: 2 arrays of 2 numbers each (CHG 2N) / 2 arrays of 4 numbers each (CHG 4N)
Permission: Read only
Pre-Condition: N.A.
Post-Condition: N.A.
Description: Charger returns two arrays of 2 bytes (CHG 2N) / 4 bytes (CHG 4N). The first array in-
dicates the state of the bay (0 – Normal; 1 – Update; 2 – Error) while the second array indicates the
kind of error as a bit map.
Error indication (Bit set to ‘1’ means error):
• Bit 0 – communication error
• Bit 1 – update error
• Bit 2 – overcurrent error
• Bit 3 – 5V charging voltage missing
Example (CHG 2N):
TX: {"bays":{"state":null}}
RX: {"bays":{"state":[[0,0],[0,0]]}}
Example (CHG 4N):
TX: {"bays":{"state":null}}
RX: {"bays":{"state":[[0,0,0,0],[0,0,0,0]]}}
