6-3 Command Communication with BL/SR/RF Series Devices
Operational commands can be sent from a host computer to BL/SR/RF Series devices that are
connected to the N-410 Series.
Command Communication Format
 Send format
• mm = 00 to 31 : ID numbers of BL/SR/RF Series devices
• Operational command : Operational commands for BL/SR/RF Series devices
* For details of the operational commands for BL/SR/RF Series devices, refer to the User's Manual for
each device.
 Return format
A N-410 Series device returns a response to the host computer in the following formats when
receiving the operational command for the head that is connected to the N-410 Series device.
• mm = 00 to 31 : ID numbers of BL/SR/RF Series devices
• Response = OK : A response is returned when the N-410 Series device normally receives an
operational command from the host computer and send it to BL/SR/RF
Series devices.
ERRmm (mm = 00 to 99 : Error code) : The error code is returned when an
operational command sent from the host
computer is invalid.
NC : Non-connection error. This error is returned when a connection of the head
that has an ID number to which an operational command is sent cannot be
confirmed.
NG : Operational error is returned when a head that has an ID number cannot
receive the command because it is ON.
 Header/Delimiter
When the command format is + , the response format is + .
When the command format is , the response format is
.
