Interactive Mode Commands (IMC = 0x0A)
Each (IMC has a function number parameter corresponding to the desired function,
which may have one or more parameters.
Example: < IMC > < buzzer function ><ON, time-out 80 ms>
Command: 0x0A 0x01 0x01, 0x00, 0x10, 0x50
Interactive commands are used to control product functions remotely. Interactive
commands can use parameters sent with the command and/or parameters already set
in the product (e.g., default settings, remote control setup commands).
Table 4-20 shows the IMC frame examples.
Note: Interactive commands are not activated by default, the special IMC activation
function must be sent to enable IMC functions.
Note: In IMC, your Sabre 1555 remains active, which means it is drawing current.
(The current consumption information is listed in Table E-3, “Sabre 1555 Current Use
with RF Power On,” on page E-4 of this manual).
Example: The host sends an RF_Auto_Run command with a 10 s time-out parameter
(if the product is in RFID Write Mode, the tag write is performed using the write
address and write string already programmed in the product, see “ RFID Auto
Configuration Commands” on page 4-46). Table 4-21 lists the format for the IMCs.
