Making Settings and Connections
Use the following steps for installation.
• RS-485 master unit N-410
• BL Series barcode reader, SR Series 2D code reader, RF Series RFID system
The following units are compatible with the N-410.
BL Series- BL700/600/500/180/210 Series
SR Series- SR-500, SR-510
RF Series- RF-500, RF-550
• RS-485 power source for multi-drop (N-48, BL-U1, NX-50RS)
Each BL/SR/RF Series device requires its own communication unit.
• RS-232C type communication unit (BL-U2)
When using an N-48 to power a multi-drop network, a separate communication unit will be
required to change settings on any of the BL/SR/RF Series devices because the N-48 does
not include an RS-232C.
This is not required when using a BL-U1 or an NX-50RS to power a multi-drop network.
• RS-232C cable for N-410
This cable connects the N-410 to the host computer.
Be sure to use a cable with the proper pin settings for the computer or PLC that you are using.
• RS-232C cable for BL/SR/RF Series settings
This is the cable used to connect the computer, BL-U1, BL-U2 or NX-50RS to the computer
when changing settings on a BL/SR/RF Series device. This cable is different than the RS-232C
cable for the N-410 and must be prepared separately.
Refer to the user’s manual for each device for more information about wiring.
• Twist pair cable for RS-485
Use this for the settings cable.

• Host computer
Use a computer with an RS-232C.
It is possible to exceed the data handling capacity of the host computer when large amounts
of data are being sent from multiple BL/SR/RF Series devices.
In such cases, reduce the number of BL/SR/RF Series devices connected or use a host
computer with a higher data handling capacity.
