43Power switching configurationPower switch configuration comprises two main steps:• Configure the POWER CONTROL serial port to the same speed as used by thepower switch box(es), either via configuration menu or via configurationpage.• Configure power ON and OFF strings for each relevant host computer.For each power port there needs to be a valid ‘Power ON string’ and similarly anappropriate ‘Power OFF string’. In each case, the strings are a short sequence ofcharacters that combine a port address and a power on or off value.If a particular computer has more than one power input (and thus requires anequivalent number of power ports to control them), collections of strings can becombined to switch all of the required ports together as a group.To configure the power sequences for each host computer1 Using VNC viewer or a browser, log on as the ‘admin’ user.2 Click the ‘Configure’ button in the top right corner.3 Click the ‘Host configuration’ option.4 Click a host entry to display a Host configuration dialog:Power control sequencesNote: The settings given below are for the EPS-S8 power switch - other powerswitches may require different settings. Please refer to your power switchdocumentation for details about codes required by other power switches.The structure of each power sequence (OFF and ON) is as follows:Pxy=z\0DWhere:x is the switch box number,y is the power port number,z is ‘0’ for OFF or ‘1’ for ON, and\0D represents Enter (or Carriage return).Example 1To switch ON port 5 of switch box 2, the code would be as follows:• Power sequence: P25=1\0DExample 2To switch OFF port 8 of switch box 3, the code would be as follows:• Power sequence: P38=0\0DFor details about operating this feature, see Power switching (viaconfiguration menu) or Power switching (via viewer) within theOperation chapter.To control two or more ports simultaneouslyYou can control up to four power ports using a single sequence. This is doneusing the same command structure as shown above, plus a delay command,for each port. Immediately following a port command, insert the characters‘\*’ before the next port command, and so on up to four ports. For instance, toswitch on ports 1 and 2 in the first power switch, the command line would be:P11=1\0D\*P12=1\0D5 If necessary, configure other parameters (Name, Users, Hot Keys - MORE).6 Enter the Power control sequences in the Power On and Power Off fields ð7 Click OK to close the dialog and then click the Save button in the main HostConfiguration window to store the details.
