Note:V+,IN1andIN2shareacommonground(i.e.notoatingorisolatedfromeachother).

USBconnection

A‘TypeAtoMini-B’USBcableisrequiredtoprogramandcustomisetheOM-SGD-24-M.Ittypicallytakes10secondstosendaconguration,

withanadditional5secondsneededforthehardwaretoreset.

TheOM-SGD-24-McanbepowereddirectlyfromUSBandiscompatiblewithbothUSB1.1andUSB2.0.Thescrewterminalsandadvanced

connectorcanremainconnectedwhilstusingUSB,butitisnotnecessaryforV+tobepowered.

Theinputvoltagerangeisdecidedusingthetwovoltagesthattheuserentersinthe
scalingsectionofthePanelPilotsoftware.Thesoftwareusesthesmallestrange
available,whichcanaccommodatebothofthevoltagesenteredbytheuser.The
absolutemaximumvoltageinputis40Vd.c.

Forexample:

Enteringavoltagescaleof0–30Vinthesoftwarewillusethe0–40Vrange.
Enteringavoltagescaleof0–3Vinthesoftwarewillusethe0–4Vrange.
Enteringavoltagescaleof5–15Vinthesoftwarewillusethe0–20Vrange.
