6. s Manual Introduction Non standard Baudrates Moxa s UART ASIC supports most non standard baudrates in the range 50 bps to 921 6 Kbps In fact supported baudrates are much denser towards the lower values For example no baudrates are supported between the integers 5320 and 5323 but 49 baudrates are supported between the integers 387 and 388 Of course this is the way it should be since serial devices that require using non standard baudrates generally use slower baudrates Before using a serial device that requires using a non standard baudrate you must first check that the DA 681 supports a baudrate within the tolerance specified by the serial device manufacturer Use the following formula to calculate which baudrates are supported by the DA 283 A Baudrate 921600 N M 8 bps for N 1 2 18431 M 0 1 2 7 or B Baudrate 8 x 921600 K bps for K 8 9 147456 If you are a programmer and you need to write a driver for your serial device then you may need to use formula A If you have a serial device that requires using a non standard baudrate then you can use formula B to determine if the DA 681 supports a baudrate within the tolerance specified by the serial device manufacturer Example Your serial device requires using a baudrate of 5340 bps and has a tolerance of 2 bps Can the DA 681 be used with this device Solution Set formula B to the desired baudrate and then solve for K 8 x 912600 K 5

Step 1 Installing the rackmount supports Take the rackmount supports out of the packages There are two rackmount ears and 12 screws Each ear requires 6 screws to attach to the rack coca ce 2 2 DA 681 Series Hardware User s Manual Hardware Installation Step 2 Installing the rackmount ears to the DA 681 Use 6 screws to attach one rackmount ear to one side of the DA 681 Repeat this procedure for the ear on the other side of the DA 681 Step 3 Installing the DA 681 to a rack Gently slide the DA 681 onto the rack and then use screws provided by the rack supplier to fix the rackmount support to the rail Note that four screws are required to attach the DA 681 to the rack Use two screws on the left side and two screws on the right side 2 3 DA 681 Series Hardware User s Manual Hardware Installation As a final check make sure that the four screws are firmly attached to the rack va ce1 Wiring Requirements The following common safety precautions should be observed before installing any electronic device e Use separate paths to route wiring for power and devices If power wiring and device wiring paths must cross make sure the wires are perpendicular at the intersection point e You can use the type of signal transmitted through a wire to determine which wires should be kept separate The rule of thumb is that wiring that shares similar electrical characteristics can be bundled togeth
