See Figure 2-8 for the location of the RJ45 connector. It is designated as TB1.
FLAG Port
The meter can have either a Flag Port or an ANSI Port. Use a standard FLAG (IEC1107
physical standard) read head to connect the meter to a PC.
Note that it has occasionally been found that some FLAG heads need to be rotated 180
degrees for them to work. If you have problems try this.
ANSI Port
The meter can have either Flag Port of ANSI Port. Standard Flag and ANSI read heads
should work with the meter. Please note that older EDMI ANSI read heads will not
work with the meter. To use a smart read head that can automatically switch polarity,
set the DTR line to be low – see
