Connect to the Controller
Step Action
CP843A
The CP843A controller is slot controller and automatically connects up to the RS485 rectifier
control bus once inserted into a power slot. However, the CP shelf must still be configured to
operate in RS485 mode. This is done by using cable assembly CC848838284 which enables the
RS485 mode of the shelf. The addition of other CP shelves utilizes the same inter-shelf cable
848738253 previously described.
• Plug CC848838284 cable assembly into J1 of the first CP shelf.
Note: the NE843G can be used to communicate with a variety of other Protocol based serial
rectifier families. Consult technical field support or sales for the availability of other kits or
application needs.

RS-232 Serial Connection For Local Port And MODEM
Connector J12 is a 14-pin right angle Molex connector used to make connection to an optional
MODEM or is brought to the front panel DB9 or RJ45 for serial Craft port access. J12 access is not
available on the NE843A/CP843A/EP843D slot-controllers or the NE843G.
Use the provided cable assembly to connect to the BSM modem. Note: the connection to the
front panel serial port will have to be removed and secured appropriately. Once the MODEM is
installed the front panel serial port will not be active.
