2.1.1 Serial Communications Jumpers
Two jumpers, labeled
RxD
and
OUTPUT
, determine
whether the ProÞbus Indicator Interface uses RS-232
or 20 mA current loop for serial communications with
the indicator. Leave the jumpers in the position shown
in Figure 2-4 for RS-232 communications; move both
jumpers to the
20mA
position if using the 20 mA
current loop option. See Figure 2-2 on page 2 for
board location of the jumpers.

Positions for RS-232 Communications
2.1.2 Serial Connections
Serial communications connections to the indicator
are made at connector J5 on the ProÞbus board (see
Figure 2-2 on page 2 for board location of J5).
Figure 2-4 shows the J5 connector layout for the
ProÞbus Indicator Interface. Table 2-1 shows the
serial communications connections between the
ProÞbus Indicator Interface and the IQ plus 800/810
indicators; Table 2-2 shows the serial communications
connections between the ProÞbus Indicator Interface
and the IQ plus 310A indicators.

Port Pin Assignments
NOTE:
The 20 mA current loop interface connection
requires that the 20 mA option be installed in both the
ProÞbus Indicator Interface and the IQ plus 800/810.
See Section 2.1.5 for information about installing the
20 mA option.

2.1.3 Profibus Network Connections
Connections to the ProÞbus network are made at
connector J4 on the ProÞbus board (see Figure 2-2 on
page 2 for board location of J4). Table 2-3 shows the
connections from J4 connector on the ProÞbus board
to the DB-9 ProÞbus connector.
2.1.4 Bus Termination Jumpers
If the ProÞbus Indicator Interface is the last device on
the network bus, install jumpers JMP3 and JMP4 on
the ProÞbus board (see Figure 2-2 on page 2 for
jumper locations).
2.1.5 Installing the 20 mA Current Loop Option
The ProÞbus Indicator Interface can communicate
with IQ plus 800/810 indicators using the 20 mA
current loop interface if the option is installed in both
the Interface and the indicator. Installing the 20 mA
option disables RS-232 communications.
