Rx105-1 is a DSM2 receiver for model railway layout control - e.g. turnouts, signals, lights. Must be used with either Tx27 transmitter or Tx3 which can be used in a bespoke controller.
Switches on the transmitter control 'channels', numbered 1-7. Each output on the receiver is controlled by one channel. A choice of three types of output are available: normal servo, 'signal' servo or light (LED). The 'signal' servo output is designed for operating a semaphore type signal with a normal servo; selecting this output type makes the servo (and, hence, the semaphore) 'bounce' before coming to rest.
The output type and servo throw can be set by programming Rx105. Preset combinations of output types are available as receiver variants 1 though 8. Variants 1-4 have five outputs with adjustable throws (Ch1,3,4,5,6). Tx27 can control seven channels (Ch1-7), so variants 5-8 are set up to control the extra two channels (Ch2,7). One variant has all outputs configured for servos so that all 7 switches on the Tx27 can be used for points. Channel numbers are the only difference between variants, select tabs Variants 1..4, Variants 5..8 or Variants 7S & 7X to see the detail for each variant.
All Rx105 outputs go to a saved position on startup. New positions are saved automatically once a minute when signals are being received. Very small changes may not be saved.
