た。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data transmission stirrup in which a central control device and a plurality of terminal devices are connected through a communication line and mutually transmit data. It is used by receiving data back sequentially from multiple terminal devices based on a communication request signal from the control device, but in the case of devices that were previously used, the power switch of the terminal device is turned off. In this state, even if a communication request signal was sent from the central control device to this terminal device, no response signal was emitted from the terminal device. Therefore, in such a case, the central control device It is not possible to confirm whether contact is established with the armpit terminal device, and the armpit terminal device becomes disconnected only after waiting for a considerable period of time without providing transmission service with other terminal devices. However, it is not possible to confirm whether the abnormality is due to the terminal device's power switch being open (OFF) or some other malfunction, and as a result, the data transmission equipment Usage efficiency and reliability were significantly reduced.

後端末機器６Ｃとの間でデータ伝送を行なう場合にも前
記と同様にして行なわれることとなる。Next, the operation of this data transmission device will be explained. For example, when a communication request signal for the terminal device 6AK is transmitted via the transmission line 5a according to an instruction from the transmission controller 2 of the central control device 1, the power switch 11A of the terminal device 6A is turned OFF.
Even if the power switch 11AK is activated, the short circuit switch IOA is turned on and the transmission lines 5g, 5 are turned on.
4 is short-circuited, the communication request signal is inputted to the central controller 1 again through the short-circuit switch 10A and the transmission line 5Aft. Therefore, the transmission controller 2 of the central control device 1 responds to the terminal device 6 by returning the same communication request signal.
It can be confirmed in a short time that communication cannot be made because the power switch 11A of A is turned OFF.0 Then, if it is necessary to contact, for example, the terminal device 6B, the central control device 1 In this case, the communication request signal is transmitted to the terminal device 6B via the transmission line 5m according to the instruction from the transmission controller 2 without wasting the priest's time. In this case, the transmission controller 7
If the power switch 11B of B is turned on, the shorting switch 10Bt-j is turned off in conjunction with this, so the communication request signal is input to the transmission controller 7B via the receiver 9B. Ru. And the transmission controller 7B is
Response data based on the input communication request signal is transmitted to the central control device 1 via the driver 8B and the transmission line 5h, and data is transmitted between them. Thereafter, data transmission with the terminal device 6C is performed in the same manner as described above.
