Multi-gateway. Bidirectional. Standby loss of only 0.5 watts. Series installation device for mounting on mounting rail. The gateway is only 1 TE wide, but can be used several times: For coupling up to three radio receiver modules, for direct connection via the RS232 interface with the PC, for connecting with the bus components of the older series 12 or as a bus connector of two RS485 buses of the series 14. Connection to the Eltako RS485 bus. Cross-wiring bus and power supply with jumper. The hold terminal is connected to the FAM14 or FTS14KS. Radio receiver modules are connected in parallel to the sub-bus terminals RSA2 and RSB2 as well as the power supply terminals GND and +12V. Up to 10 push-button input modules FTS12EM may be connected in series to the sub-bus terminals RSA2 and RSB2, possibly in series with radio receiver modules FEM. The PC connection is made by connecting to terminals Tx and Rx. Series 12 actuators are connected to the RSA2 and RSB2 sub-bus terminals. There is n
