Power-On Sequence
Th e L4532A/ 34A may t ake up to a min u t e t o boot, du r in g which you will
see some p rogr ess messages on its disp lay. Then t he d isp lay p rovides
t hr ee sets of in for mation , in sequen ce:
ID and revision message
Fir st, t he in str umen t will pr ovide an ID an d

Th e fir st lin e disp lays t he mod el n u mber. Th e secon d lin e is in th e for m

, wher e:
f.ff
is th e in str umen t's in st alled fir mwar e ver sion .
bb
is t he FPGA ver sion for t he d igitizer 's d igit al board .
gg
is t he FPGA ver sion for t he digitizer 's chan n el 1- 2 an alog boar d.

is t he FPGA ver sion for t he digitizer 's chan n el 3- 4 an alog boar d.
The FPGA ver sion s p rovide u sefu l in for m ation for in str u men t ser vicin g.
MAC Address
Then , t he in str umen t will disp lay its fixed MAC ad dr ess (a
typ ical examp le is shown ; ever y LAN in str u men t has a MAC add r ess

Idle State Message
Up on comp letin g t he p ower- on sequen ce, t he
in str umen t disp lays t his id le st at e message. If a LAN con n ection is
est ablished , the in str u men t also d isp lays th e IP add r ess:
In LAN con figu r ation s with ou t a DHCP ser ver, allow ap pr oximately 60
secon ds for th e Au tomatic IP featur e t o assign an IP ad dr ess to th e
d igitizer.
