Product Model: IOM-16X
Overview：
The product adopts the mainstream ARM 32-bit microprocessor that supports Modbus RTU for rapid expansion of controller I/O modules.The design of universal input and output greatly improves the flexibility of the device and saves costs.Non-human damage, warranty is 2 year.
Protocol specification：
Supports Modbus RTU protocol for fast network connection with controllers that support the protocol and rapid I/O port expansion. Please refer to the instruction of Modbus RTU test tool for details.
Main Parameter：

Note: Do not rewrite the EE configuration frequently! After this configuration is modified, the ERR red light on the mainboard will illuminate to indicate that the EE is being written. Please wait until the ERR light goes out before powering off or restarting the device.
Frequently asked questions：
1.ModbusRTU common question:
Q ① : What is the default communication parameter for the module?
A ① : The default communication parameters of the ModbusRTU module: baut rate 9600, data-bit 8, stop-bit 1, no parity, and device ID is 1.
Q ② : How to modify the communication parameters of the module?
A ② :Use third-party software Modbus Poll, follow chapter “ Description of Definition for Registers”, Read the data from registers 41001, 41002 and 41003, which represent device addresses (1-31), communication baud rate of 9600 and Check bit（0 none;1-odd;2-even）. Modify the module communication parameters according to the description in the "Instructions" column. After power failure and restart, the set parameters take effect. (Station number 41001 displays the station number set by the current dip switch. If software is required to set the station number, the dip switches 1/2/3/4/5 must be placed in the OFF position.)
Q③: How to modify the device ID?
A③: Refer to the table below for the internal dial of the hardware (binary dial code).The dip switch has 5 bits, each representing a numerical value. When pushed to the OFF position, it is set to 0. When turned ON, it represents 1, 2, 4, 8 and 16 in sequence. When turned ON, it represents the sum of numerical values, which equals the address code of the device. If the device ID is set to "11", dialing codes 1, 2, and 4 will push it to the ON position, and dialing code 3 will push it to the OFF position, which is equivalent to 1+2+8=11. Note: The maximum address code is 31.
