Communication Wiring
The connection of the PC to the 61-805 must be done through the power supplier set, which needs to be connected to
power. Perform the connection using the two wires factory-delivered with the 61-805.
One cable links the 61-805 to the power supplier, and the other cable is a standard RS232 connector.
When starting communication tasks take into account:
• Communication parameters of the 61-805 and the PC must fully coincide.
• Connections must go through the power supply.
• The 61-805 cannot be into the setup menu.
Communications Software
The 61-805 power analyzer comes complete with a powerful software package, Power Vision, to assist in analyzing the
data captured by the power analyzer. See the Power Vision instruction sheet for complete details on the operation of
this software.
A confirmation is required prior to formatting the internal memory. Formatting the memory of the power ana-
lyzer will delete all stored data.
Note: Do not turn the 61-805 off during the memory format process, the display will show an error message and the
process should be redone.
Clear Menu
The clear menu resets saved parameters within the power analyzer.
Energy
The power analyzer has several energy counters, which keep their values even after the analyzer is turned off. These
values can be reset by selecting the energy submenu and pressing enter.
MAX/MIN:
The maximum and minimum values are stored by the 61-805, even after the analyzer is turned off. These values can be
reset by selecting the MAX/MIN submenu and pressing enter.
Communications Protocal
Demand format
The demand format is: $00CCCAA.... ch [LF]
(example = $00RVI75 )
The answer format is: $00AA.... ch [LF]
$ Any message starts with this symbol (ASCII-36)
PP The identification code for the portable AR5 is always 00
CCC COMMAND
AA ARGUMENT (decimal-ASCII)
Ch CHECK-SUM: Check-sum of all the elements forming the message. It is calculated
with the decimal addition of all the previous bytes in ASCII and translating the result
to hexadecimal. Two digits are taken.
example = $00RVI —> 36 + 48 + 48 + 82 + 86 + 73 = 373
373 decimal ∫ 175 hexad. CHECK-SUM = 75 —> $00RVI75
[LF] [ LF ] LINE FEED indicates the end of the message (ASCII-10)
