Operation
The SZ-IO receives its operating settings during
system startup. A device database containing
settings is transferred to the SZ-IO after it has been
addressed. This database includes settings for:
• CCO behavior (maintained vs. momentary)
• Momentary pulse time
• CCI programming action
• System presets
LED Feedback
The SZ-IO provides 7 LEDs for user feedback:
Status LEDs
LEDs 1 through 5 provide feedback for the CCOs
and CCIs. The display mode (CCO vs. CCI status)
depends on the position of DIP switch 7: The LED
lights when the CCO is active or when the CCI is
closed.
Switch up (on): CCI status displayed
Switch down (off): CCO status displayed
Addressing Mode LED
LED 6 will blink during addressing. A slow blink
(on for 3 seconds every 4 seconds) indicates an
unaddressed device. A fast blink (once per second)
indicates an addressed device. When not in
addressing mode, this LED is off.
RF Link Activity LED
LED 7 will blink when the SZ-IO receives or transmits
an RF packet.

Diagnostic Mode Operation
1. E nter diagnostic mode. Move DIP switch 6 to the on
(up) position. LEDs 6 and 7 will flash together (once
per second) while the unit is in diagnostic mode.
2. S elect CCOs to override. Use DIP switches 1
through 5 to select which CCOs to close when the
addressing (ADDR) button is pressed. (The DIP
switch number corresponds to the CCO it controls.)
3. A ctivate the CCOs. Press the addressing button to
activate the CCOs you set using the DIP switches
in the previous step. The CCOs will remain active as
long as the button is pressed.
4. E xit diagnostic mode. Move DIP switch 6 to the
off (down) position. LEDs 6 and 7 will stop flashing
together.
Note: Diagnostic mode will exit automatically after 5
minutes of inactivity. Pressing the addressing button
will reset the inactivity time and the unit will remain in
diagnostic mode.
