Through Mode

Using Through Mode, you can connect media converter to PC's COM ports to access the other devices connected to media converters on other place over LAN.
In Through Mode the media converter does not use its own device drivers.

Through Mode uses two media converters in a pair.
It is used like extending an RS-232/422A/485 cable with a network (LAN) cable.

The device ID of the media converter can be specified using the rotary switch on the main unit (or the Setting Utility）.
By setting the same device ID value for two media converters, they are paired.

When specifying the device ID using the rotary switch on the main unit, a maximum of 15 pairs can be used due to the rotary switch's limitations.
Up to 254 pairs can be used by specifying the device ID in the Setting Utility.
For details, see [Setting Utility] - [Edit] - [Basic Settings].

Please set the communication conditions with the other device (baud rate, parity, stop bit, etc.) on the media converter using the Setting Utility.
By simply adjusting the communication conditions, you can access devices without changing the serial communication program you are currently using.
For details, see [Setting Utility] - [Edit] - [Basic Settings] - [Detail Settings].

In addition, Through Mode is only accessible under static communication conditions set in the Setting Utility.
Dynamic changes to communication conditions such as baud rate are not supported.

■ The use of Through Mode

This is useful when you want to control equipment located beyond the RS-232C specified cable length (maximum 15 m).
Part of the RS-422A/485 cable can be replaced with a network cable (wired LAN) or wireless (Wi-Fi), which makes cable installation easier.
