1. ADAM 4542 Fiber Optic to RS 232 422 485 Converter User Manual Packing List Before you begin installing your card please make sure that the following materials have been shipped e 1 x ADAM 4542 Module with DIN rail mounting bracket 1x ADAM 4542 User Manual e 1x Panel Mounting Bracket e 1 x Cable for 9 pin to 3 pin If any of these items are missing or damaged contact your distributor or sales representative immediately Introduction Fiber optic transmission offers the benefits of wide bandwidth immunity to EMI RFI interface and secure data transmission The ADAM 4542 can be used as an RS 232 422 485 point to point or point to multi point connection for transmitting and converting full half duplex signals and their equivalents within a fiber optic environment Fiber optics are the perfect solution for applications where the transmission medium must be protected from electrical exposure lighting atmo spheric conditions or chemical corrosion The ADAM 4542 is specially designed to link various machinery equipped with RS 232 422 485 communi cation ports such as computer systems or manufac turing machines Using standard SC connectors the module s fiber optic port can accommodate a wide range of fiber optic cable ADAM 4542 also supports the redundancy requirement You can use two pairs of ADAM 4542 for a redundant architecture This spe cial design offers higher reliability For more information on th2. AM modules do not change the default setting of the converter since ADAM modules have a fixed data format of ten data bits The option of changing to 9 11 or 12 bits is for use with other modules other than ADAM modules that have different data formats Should you change the ADAM module s data format be aware that you will also have to change the data format on all the other modules in the network SW2 Switch 2 sets the baud rate The options range from 1200 bps to 115 2 kbps The factory default is 9600 bps Be aware that when you change the baud rate you also have to change the baud rate for all of the connected modules accordingly If the RS 232 422 mode is ON the baud rate does not need to be set ADAM 4542 Baud Rate Setting SW2 Baud Rate 1 2 3 4 5 6 7 8 9 1200bps ON OFFOFFOFF OFF OFFOFFOFF OFF 2400bps OFF ON OFF OFF OFF OFFOFFOFF OFF 4800 bps OFF OFFON OFF OFF OFFOFFOFF OFF 9600 bps OFF OFFOFFON OFF OFFOFFOFF OFF 19 2 kbps OFF OFFOFF OFF ON OFFOFFOFF OFF 38 4 kbps OFF OFFOFF OFF OFF ON OFFOFF OFF 57 6 kbps OFF OFFOFF OFF OFF OFFON OFF OFF 115 2 kbps OFF OFFOFF OFF OFF OFFOFFON OFF RS 232 422 OFF OFF OFF OFF OFF OFF OFFOFF ON 2 ADAM 45424 User Manual JP2 The ADAM 4542 supports a redundancy feature You can use two pairs of ADAM 4542 to create a redundant connection The ADAM 4542 can be set as Primary or Secondary in the redundant architecture by JP2 The Primary co
