1. 13 CMB16D Nitty Gritty This section is for technical types who are not sure whether their application would be a good match for the CMB16D There are two banks of MOSFETs bank 1 for output channels 1 to 8 and bank 2 for output channels 9 to 16 The positive outputs of a bank are all tied together and connected through their fuse to the positive power input A MOSFET is used to ground the load connected to its channel so positive power is always present at the load The MOSFETs are Pulse Width Modulated at 400 Hz 1 400 second 2 5 milliseconds There are 240 possible intensities This means that in each 400 of a second the grounding pulse is somewhere between 0 240 2 5 ms off and 240 240 2 5ms full on Connecting Controller to PC Data Cable If you have not installed your RS485 adapter do it now If you have an SC485 PC serial port adapter shown on the left below you need only plug it into an available PC 9 pin serial port The cable from an SC485 serial adapter to the first controller is limited to 100 or less Cable length to the first controller is not so limited for USB adapters CMB16D If you have one of the USB adapters shown center and right above follow the installation instructions that came with the adapter Testing the CMB16D To perform this test the CMB16D must have a unit address between 01 and FO and it must be powered up and connected to the PC The LED on the CM2. Power Input for Logic amp Accessories Figure 1 Setting the Unit ID Use the Unit Address Switches to set the board s controller address In figure 1 the top rotary switch sets the most significant digit and the bottom switch sets the least significant digit To set the controller address to 01 set the top switch to 0 and the bottom to 1 as depicted in figure 1 Legal unit address settings are 01 to FO hexadecimal in decimal that would be 1 to 240 CMB16D Data Cable Connections The Phone Cable In jack is an RJ11 The two CAT5e jacks are RJ45s Connecting to PC If you are using telephone cable to connect your controller to the PC RS485 adapter plug one end of the phone cable into the adapter and the other end into the Phone Cable In jack See figure 1 If you are using Cat5e LAN cable to connect your controller to the PC RS485 adapter plug one end of the data cable into the adapter and the other end into either of the CAT5e Cable In or Out jacks Connecting to Other Controllers If you are using telephone cable to connect your controller to another controller go from either CAT5e jack on one controller to the Phone Cable In jack on the other controller See figure 1 If you are using CAT5e LAN cable to connect your controller to another controller go from either RJ45 jack on one controller to either RJ45 jack on the other controller See figure 1 Status LED LED blinking
