Byte HH multiplying factor: 0.1 (i.e. actual = byte HH in decimal
×
0.1 seconds)
F3: Jam
Format: two bytes in format 0xHHLL, where LL is the pickup level and HH is the time delay
Byte LL range: 0x00, 0x64 to 0xFA (i.e. 100 to 250%), where 0x00 is disabled
Byte HH range: 0x00 to 0xC8 (i.e. 0 to 1000 seconds)
Byte HH multiplying factor: 5 (i.e. actual = byte HH in decimal
×
5 seconds)
F4: Stall
Format: two bytes in format 0xHHLL, where LL is the pickup level and HH is the time delay
Byte LL range: 0x00, 0x42 to 0x78 (i.e. 330 to 600%), where 0x00 is disabled
Byte LL multiplying factor: 5 (i.e. actual = byte LL in decimal
