Wakeup Nulls
The KDC sends three leading Null bytes to wake up the
Bluetooth
connected device. This
feature may be disabled if the
Bluetooth
connected device does not require additional bytes to
wake up. KDC500 doesn’t support this option.
Autolock Time
The iPhone/iPad/iPod touch loses incoming Bluetooth data while in sleep mode. To prevent data
loss, you may set the KDC Autolock time to the same Autolock time of your iPhone/iPad/iPod
touch, to use the automatic wakeup feature in HID mode. KDC500 doesn’t support this option.
If the Autolock time is set to more than one minute and the barcode scan interval is larger than the
auto-lock time, there will be a one second delay of barcode transmission. The auto-lock time would
be set as 0, 1, 2, 3, 4, 5, 10, 15 minutes. 0 means the iPhone/iPad/iPod touch never enters sleep
mode. This option may not need from iOS 5.x.
HID Keyboard
The user may select an international keyboard – English, German, French, Spanish, or Italian. It
is also required to set the host keyboard with the same keyboard as selected in this menu.
KDC500 doesn’t support this option.
HID Initial and Inter-Character Delay
Certain applications may not process HID input fast enough and may lose some characters
during transmission. Users should increase initial and inter-character delay to prevent data loss
during HID transmission. KDC500 doesn’t support this option.
⚫ HID Initial Delay: Defines the initial delay between 1 sec to 10 sec before data
transmission in HID mode.
⚫ HID Inter-character Delay: Defines the inter-character delay between 10msec to
100msec in HID mode.
Control Character Transmission in HID mode
Control characters between ASCII values 0x00 and 0x1F may be replaced by the ALT+Numpad
or ^+Character or replaced with ‘|'. KDC500 doesn’t support this option.
⚫ Disabled ➔ Transmit the original control character.
⚫ Alt+Numpad ➔ Transmit Alt+ ASCII value from Numpad.
⚫ ^+Character ➔ Control characters would be substituted as shown in the following
table.
⚫ Replacement to | ➔ Control characters would be substituted as “|”.
