Feature

Specially designed free software allows you to conveniently parameterize your AD105C.
First-time setup enables you to confirm communication protocol and commands. It is recommended to use the dedicated free software.

* Specially designed free software (supported OS: Windows 7, 8, 10) and manual can be downloaded from here.

AdjustmentInitial condition confirmation is available via computer.

Initial setting. Peak hold of process time and filter simulation is available via computer software. It makes your product development more convenience that frequently feth date is not necessary.

ConfirmationOperating confirmation is available via graph function.


Thanks to graph function, change of weight value. Process time monitoring, peak value confirmation is available and frequently feth date is not necessary.

Caution
The AD105C motherboard is not protected against electrostatic discharge. Relevant precautions must be taken when handling in during installation in the transducer.
*For 4-wire RS-485 devices, use jumper wires. (Refer to the manual provided with the device.)

Important information to EMC protection.
Be sure to install AD105C motherboard into a Grounded Metal case and use shield cable.
Both of shield cables should connected with AD105C motherboard's Grounded metal case.

Adjustment of AD105C is to be made through communication using RS interface, which requires presettings including address (ADR), baud rate (BDR), parity bit (PAR), terminator (TEX), common output format (COF), etc.

Default settings Address: 31, Parity bit: None, Stop bits: 1
Baud rate: 9600 bps, CRLF: ON

*Number of digits of data received varies depending on the capacity of PLC. (Reference: 15 bits ±10000 or less)
