Removing An Existing Card
!
ATTENTION: An anti–static wrist grounding strap must be
worn at all times while performing any reconfigurations or
modifications to the Powermonitor Display/Block Module.
Failing to do so may permanently damage the static–sensitive
components inside the Powermonitor Display/Block Module.
1. Turn off all power to the Powermonitor Display/Block Module.
!
ATTENTION: Voltages may still be present when supply power
is turned off to the unit. The unit will generally be powered by
one source and will be monitoring another source. Turn off or
disconnect all voltages applied to the unit. Failure to do so may
result in personal injury or death.
2. Remove the four machine screws holding the rectangular communications
card mounting plate on back of the Powermonitor Display/Block Module.
case.
3. Carefully pull the plate away from the main chassis using the pull tabs to
remove the card.
The circuit board of the communications card has a jumper labelled Jl. This
jumper has two positions, which determine the communications mode.
Figure 1 illustrates the jumper in the bottom position for RS-485 mode. If
the RS-232C mode is desired, move the jumper into the top position.

(Bottom Position)
The Powermonitor Block Communications card has a jumper labelled J1.
This jumper has two positions, which determine the communications mode.
The jumper is configured for RS–485 mode from the factory. If RS–232C
mode is desired, move the jumper over the two pins closest to the LEDs.
Remote I/O Addressing
The Powermonitor Block Communications card uses two DIP switches to
configure the RIO address, starting quarter, data rate, and last rack. The DIP
switches are shown in the default factory configuration.
