Cable connection
XPass D2 can be used as an RFID card reader by connecting to a master device or a CoreStation.
Power supply connection
NOTE
• Use a power supply adaptor of DC 12 V (± 10%) with a minimum of 1,500 mA which has obtained the approval of IEC/EN 60950-1. If
you wish to connect and use another device to the power supply adaptor, you should use an adaptor with a current capacity which
is the same or larger than the total power consumption required for the terminal and another device.
RS-485 connection
NOTE
• Use an AWG24 twisted pair with a maximum length of 1.2 km for the RS-485 cable.
• If connecting with a RS- 485 daisy chain, connect the termination resistor (120 Ω) to both ends of the daisy chain connection. If
connected to the middle line, the signal level becomes smaller and the communication performance will deteriorate. Make sure to
connect it to both ends of the daisy chain connection.
