INTEGRATION OVERVIEW
The Galaxy
635
Dual Serial Interface (DSI)
board connects to the AD-400 PIM
using RS-485 two-wire, multi-
drop configuration. The AD-400 PIM maintains a wireless connection to the AD-400 Readers (door units) on
one side of the system. The AD-400 PIM connects to the Galaxy access control panel via the DSI 485 board
on the other side of the system. The AD-400 PIM converts the data from wireless protocol to RS-485 and
visa-versa. The door events and credentials presented at the wireless door are sent thru the PIM to the
Galaxy Panel. The Galaxy Panel returns the access decision to the PIM & logs event with the Comm. Server
and SysGal database.

IMPORTANT
The
Card + PIN
“high-security mode” is not supported at this time.
Each section of the DSI board can support the same card format (i.e. either all Wiegand Readers or
all ABA Reader). The diagram above shows a system that has mixed card technology. You can see
how you must install the ABA readers on a different 485-network bus (DSI section).
