Functions
Internal Memory Info.
It sets number of events, alarms, screen captures, and
storage options at internal memory.
It sets also internal memory storage options. When internal
memory uses all, it operates overwrite (deletes oldest data)
or stop (stops saving).
Firmware update
Update firmware.
Download the firmware at our web site (www.autonics.com).
Save the downloaded firmware at the top-level folder on
USB/SD memory and touch [Menu]-[System Info.]-[System
Info.].
When completes firmware update, re-boot the unit.
Do not turn OFF the power during firmware update.
RS422/485 Communication setting
Setting items are only available to check by communication.
RS422/485 communication makes set or monitor parameters at external upper system (PC or graphic panel, etc.) and uses
transfer data. It is recommended to use our dedicated software program DAQMaster for monitoring.
If you want to develop monitoring program not using our DAQMaster program or to use the related Modbus program, please
refer to user manual for communication.
Visit our homepage (www.autonics.com) to download DAQMaster program, and user manual for communication.

※ 1. In case of Ethernet connection, and connecting through the network such as network hub (HUB) and gateway, etc, there is no distance
limit, but it is recommended to use min. network. Please use communication cables which is satisfied the below conditions.
· RS422/485 communication: Shield Twist Pair over AWG24, characteristic impedance 100Ω,
· Ethernet communication: Over CAT5E, cable max. length: 100m
· USB communication: Single cable built-in ferrite core within 1.5m
※ USB device is recognized as USB to Serial device and communication speed: 115200bps, start bit: 1-bit, data bit: 8-bit,
parity bit: none, stop bit: 1-bit are fixed.
Application of system organization
Computer
※ It is recommended to use Autonics communication converter; SCM-WF48 (Wi-Fi to RS485·USB wireless communication converter, sold
separately), SCM-US48I (USB to RS485 converter, sold separately), SCM-38I (RS232C to RS485 converter, sold separately).
Please use twisted pair wire, which is suitable for RS485 communication, for SCM-WF48 and SCM-US48I.
