The P-IAMC-G communicates with remote Access Panels or Microphone Stations
through eight electrically isolated full duplex RS422 serial ports. When Access Panels
need to communicate with the P-IAMC-G card using field wiring, use the Passive
Terminal Block card (P-PTBC-G) to convert the field wiring to a compatible RJ45 cable
that can connect directly to the P-IAMC-G card.
When remote Access Panels are located in a hazardous area, use Zener safety barriers
mounted on an IS Barrier card (P-IS-BARRIER-G) between the P-IAMC-G and the field
wiring to provide a safe interface. You can connect two Access Panels or Microphone
Stations to each IS BARRIER card.
NOTE
: The service model for the Internal Access Panel Multiplexer card is
K-P-IAMC-G.
