+ | ===== Description ===== | ||
+ | Many software control programs do not have the ability to use the 7 control bits as a Byte.\\ | ||
+ | They use the standard method for controlling Turnouts.\\ | ||
+ | This board is only attachable to J5 of GCA145/ | ||
+ | For each brand name, there is special firmware available, see below, | ||
+ | It receives the standard codes and converts that to the 7 outputs, needed to select position 1..48 on GC145/ | ||
+ | Also an isolated feed-back is provided.\\ | ||
+ | Feed-back is free to be used with systems like S88.\\ | ||
+ | The on-board opto-couplers isolate the didital rail signals and feed-back from the board.\\ | ||
+ | Feed-back is very nice inside Rocrail environment, | ||

+ | ===== Address selection ===== | ||
+ | The adresses are identical to the Märklin / Fleischmann / Lenz standard, depending on the programmed firmware.\\ | ||
+ | **N.B. Besides the short manual, as presented here, it is also adviseable to consult the original manual for your turntable dekoder.**\\ | ||
+ | |||
+ | \\ | ||
+ | |||
+ | ===== Feed-back ===== | ||
+ | GCA174MR has a feed-back signal, to inform Rocrail that turntable is ready to move trains on/off.\\ | ||
+ | This feed-back signal is electrical (galvanic)isolated from the GCA174MR.\\ | ||
+ | By connecting J2 pt 3(+) and 4(-) to any device like S88 units or derivates, | ||
+ | Settings in Rocrail , see Position sensor\\ | ||

+ | GCA174MR is priovided with 8 leds for indication of decoded turntable position.\\ | ||

+ | ===== Extra modification on blue coloured GCA145(MGV145) boards ===== | ||
+ | {{ : | ||
+ | GCA174 needs 5 Volt which is by default not available from J5 on older version boards GCA145.\\ | ||
+ | Therefore, a diode 1N4003 (or equivalent) should be mounted under J5 as this picture shows.\\ | ||
+ | **NOTE:** The latest green GCA145 pcb has this diode(D10) on board, so no further attention needed.\\ | ||
