5702269-C I/O Communication and Control 4-51
Pinnacle™ Plus+ 10 kW
The mode of differential communication (that is, RS-485 or RS-422) is selected via
the jumper labeled as such. You must first remove the unit cover; then place the
jumper across pins 1 and 2 for RS-485 (labeled 485). Place the jumper across pins 2
and 3 for RS-422 (labeled 422).
If you have selected RS-422 or RS-485, you also have to set two terminator jumpers.
If have selected RS-422 or if your Pinnacle Plus+ unit is the last device on an RS-485
multi-drop chain, place the jumpers across pins 1 and 2 (labeled Term.). If you have
selected RS-485 and your Pinnacle Plus+ unit is not the last device on a multi-drop
chain, place the jumpers across pins 2 and 3 for no termination.
SETTING THE PINNACLE PLUS+ UNIT’S AE BUS ADDRESS
Use the DIP switch (see Figure 4-13 on page 4-49 and Figure 4-14 on page 4-49) to
set the unit’s AE Bus address (see Table 4-15 on page 4-52).
• For units with a single output, an allowable address is between 1 and 31.
• For units with a dual output, the address switches pertain to Side A. Side B is
addressed by adding 15 to the address of Side A. Allowable addresses for Side A
are 1 to 15. Side B addresses will then be 16 to 30 respectively.
• For units with a dual output and two AE Bus cards—one AE Bus card in the Serial
port and one AE Bus card in the User port—you set the AE Bus address as you
would for a dual output. The address switch on both cards pertains to Side A, and
Side B is addressed by adding 15 to the address of Side A.
Note: You can set both addresses on each card to be the same address for side A,
or have two different addresses for side A (as shown in the example
below).
For example:
4
For the AE Bus card in the Serial port, you set the address switch for Side A
to 3. If you communicate to this card at address 3, you control Side A of the
unit. If you communicate to this card at address 18, you control Side B.
4
For the AE Bus card in the User port, you set the address switch for Side A to
1. If you communicate to this card at address 1, you control Side A of the unit.
If you communicate to this card at address 16, you control Side B.
Disconnect all sources of input power before working on this unit or
anything connected to it. In addition, take proper ESD precautions before
removing the unit's top cover to position jumpers.
