Communication Protocol The communication protocol is described below. • When the SRP-X700P has received a command from computer successfully, the SRP-X700P returns “ACK” (Acknowledge). When the SRP-X700P fails to process the command due to reception error or others, it returns “NAK” (Not Acknowledge). • When a computer has sent a command, the computer should wait “ACK” or “NAK” to be returned from the SRP-X700P. Upon receipt of the return, a computer can send the next command. • If a computer do

LEVEL UP: 43[H] 4C[H] 56[H] 2B[H] (‘CLV+’) This command is used to increase the sound volume of the specified channel. When this command is sent, the sound volume keeps increasing. When the LEVEL UP/DOWN STOP command that is described later, is sent, the sound volume stops increasing. Variable range of a sound volume is from –∞ to +10 dB when the sound volume is set to the reference level 0 dB. When the power of the SRP-X700P is turned off, the sound volume level is reset to 0 dB. • Packet form
