README for Hardware Knob Boxes ============================================================ Details of configuration for first EPICS Knob Box deployment: ------------------------------------------------------------ 1. Using Digi PortServer TS 16 MEI terminal server User's guide: http://ftp1.digi.com/support/documentation/90000583_J.pdf settings nodename: ts-mcc0-kn01 subnet: LCLSINST location: MCC network closet 2. Terminal server serial ports configured with these settings (used default for all other settings): port profile profile: TCP Sockets basic serial settings baud rate: 115200 data bits: 8 parity: none stop bits: 1 flow control: none MEI serial settings MEI mode: EIA-422/EIA-485, Terminated, 2-wire transm. control:Always keep transmitter enabled advanced serial settings enable port logging 3. Setting knob box hardware address Set the hardware address to the knob box number. (Note: the software addresses the box CPU by 4 times that number. Don't let this confuse you. Just use the box number to set the hw address.) ex: Knob Box 1 hardware address is set to 1 Set the hardware address using binary addition (x*2^0 + y*2^1 + z*2^2... where x, y, z are either 0 or 1 depending on whether each jumper or switch is set or unset, aka on or off.) See notes below for the eccentricities of each box. Miranova: In the knob box there is a group of Address Select pins and jumpers. Ignore the numbers next to the pins and any pairs which were removed and soldered together. Looking only at the pins that are still intact, and using the binary number system, these are their values: 1 2 4 8 16 The box address will be equal to the sum of the pin pairs which are NOT set (i.e. NOT jumpered). For example, for box 3, jumper pin pair values 4, 8, and 16. Leave 1 and 2 un-jumpered. Knob Box Pro: In the knob box there is a group of 8 toggle switches. Each switch is a bit of the address. The least-significant bit is on the left and should be labelled so. The switches are labelled from 1, but again, their values starting from the left-hand side are: 1 2 4 8 16 ... The position labelled 'Off' or 'Rocker Down' is actually the ON position. (There is text on the circuit board indicating this, but it is easy to miss.) The box address will be equal to the sum of the switches which are set ON. For example, for box 9 set switch values 1 and 8 ON. Set the remaining switches OFF. 4. Other info: The Knob Box Pro has a hardware restore button used to set an attached device to the value it had when assigned. At this time, the SCP does not support this message, so using this button for a SCP device will have no effect.
