Memory reset procedure and manual addressing
Memory reset procedure resets all settings to factory default ones and it enables to manually configure the
address on RS485 bus.
1. Remove all connections from LCK1 and DC1 lines.
2. Place jumper on MEM contacts (fig. 2).
3. Connect LCK1 and DC1 lines.
4. Restart the device by pressing RST button and ACL LED indicator will pulsate.
5. Disconnect LCK1 and DC1 lines and RUN LED indicator will pulsate. The number of consecutive
flashes will correspond to expander’s address on RS485 bus.
6. Press RST button in a certain moment to select certain address (table 5) or press RST button after 16
flashes when ACL and RUN LED indicators are switched on to select default ID=100 address.
7. Remove jumper from MEM contacts and restart the device.

High level configuration (VISO)
The purpose of high level configuration is to define logical functioning of the expander which communicates
with the MC16 access controller and it depends on applied scenario of operation. The example of access
control system configuration is given in AN006 application note which is available at
