Figure 19: MD-N32 Configuration connecting a single panel
When using an MD-N32, for a single panel, either an RS-232
cable or Rosslare's MD-14 RS-485 converter can be used.
To connect an MD-N32 to more than one panel (up to 32
panels), Rosslare's MD-14 RS-485 converter must be used.
Connect the MD-14 between the RS-485 access control panel
network and the MD-N32 converter.
