<p>PURPOSE:To enable a central control, by connecting between a programming unit and a controller with a long distance transmission controller. CONSTITUTION:A signal produced from a programming unit 4 is converted into a transmission signal at a transmission control unit 7 and transmitted into a transmission control unit 5 via a transmission cable 6. The unit 5 restores a transmission signal to a signal produced by the unit 4 and the signal is transmitted to an interface 2 via an exclusive cable 3. Since the correspondence with a plurality of exclusive cables 2 is possible for the transmission unit, a plurality of stands of control can be coupled, allowing to be rich in extendable application.</p> |
