RS 232-Transparent-Mode (TransMode)

Configuration

 

 

6.4RS 232-Transparent-Mode (TransMode)

The section is only valid for the Mitsubishi Super Modem (MIM-A01).

The TransMode allows the remote control of a control unit (PLC) or another RS-232 device via a Mitsubishi Super Modem as if you were sitting near the device and connected locally via RS 232. All commands that you can give to this device via the local RS 232 interface can also be issued via TransMode from any telephone connection or via GSM modem.

Dial-in access can be password-protected.

An application of the TransMode command, for example, would be the control and configuration of a technical system that is connected to the Mitsubishi Super Modem via an RS232 interface.

To use the TransMode, do the following:

￿Configure the Mitsubishi Super Modem using the TransMode command

￿Connect your Mitsubishi Super Modem to the device you want to control remotely.

To do so you will need a null modem cable (usually plug-plug), for example, the "Blue Adapter".

￿Test the remote dial-in with a Mitsubishi Super Modem or another modem using a terminal program (dial-in of the Mitsubishi Super Modem).

￿The Login command for the selected Mitsubishi Super Modem must be entered

within 5 seconds of the modem connecting (see section 6.4.3). The RS 232 is then con- nected to both modems.

￿Control your remote device.

All data that you send from the PC to the local modem is transmitted over the telephone line to the Mitsubishi Super Modem AT and from this modem to the connected device via RS 232. You can operate the connected device as if you were directly sitting in front of it.

￿Close the connection by

–hanging up by the caller modem

–optional timeout in the Mitsubishi Super Modem when no more data is coming (default: 75 seconds)

6.4.1Time delays during modem transmissions

A remote connection and data conversion in both modems lead to delays in the runtime of data from PC to the control unit in comparison to a direct local connection via an RS 232 cable. Some configuration programs for control units expect a response within a few milliseconds. Errors can occur in these programs. Ask the manufacturer of these programs and control units how the timeout for the communication with the control unit can be increased to, for example, 500 ms.
