Measuring results, preselections and the status of thecontroller can be read at any time. Controlling via interface is only possible, if the remote operation modehas been preselected at the controller. During remote operation (”PC” is displayed) the controller canbe operated only via interface, the keys at the controller have no function, the warning triangle isdisplayed.Setting of the interfaceSetting of the interface parameters directly at the controller is described below. The factory set values areunderlined.➨ 1200, 2400, 4800 or 9600 BAUD➨ 7 data bits odd, 7 data bits even, 8 data bits none, 8 data bits odd, 8 data bits even➨ no Handshake, XON/XOFF Handshake, CTS/RTS Handshake➨ remote on, remote off☞ Unchangeable: Startbit = 1, Stopbit = 1Press key Mode ▲ during switching-on.☞ The controller switches to the mode to configurate the inter-face.BAUD-Rate is displayed.➨ Press key Mode ▲ or ▼ to select the BAUD rate and con-firm with key STOP (”96”=9600, ”48”=4800, ”24”=2400,”12”=1200).Data bits are displayed.➨ Press key Mode ▲ or ▼ to select the data bits and confirmwith key STOP.Parity is displayed.➨ Press key Mode ▲ or ▼ to select parity and confirm withkey STOP (”no” = no check of parity, ”O” = odd, ”E” = even).Handshake is displayed.➨ Press key Mode ▲ or ▼ to select handshake and confirmwith key STOP (”no” = no Handshake, ”HA” = RTS/CTS,”SO” = XON/XOFF).Remote is displayed.➨ Press key Mode ▲ or ▼ to select parity and confirm withkey STOP (”no” = local operation, ”On” = remote operation).☞ The controller switches to normal operation mode (processcontrol not active).+(mains switch)Set b.96Set d. 8Set P.noSet h.noSet r.no
