PIM400 Gateway and Lock Addressing

The PIM400 Gateway must be configured with a unique RS-485 communication address within each downstream port. The “low door” and “high door” range for the PIM allocates the number of readers that will communicate with the PIM or gateway. Valid reader addresses include 0 - 254. Reader address 170 must not be used.
It is recommended that the reader address range within each PIM be defined as a range of 16. This allows for adding readers in the future without re-addressing the address ranges on other PIMs.

There are not enough reader addresses to support a full complement of 16 locks on all 16 PIM400s. Therefore, care must be used not to overlap or duplicate lock addresses on each of the communication ports.

Example: The following lock addresses are only suggested addresses.

Communication Address	Low Door Address	High Door Address
PIM-0	door low = 0	door high = 15
PIM-1	door low = 16	door high = 31
PIM-2	door low = 32	door high = 47
PIM-3	door low = 48	door high = 63
PIM-4	door low = 64	door high = 79
PIM-5	door low = 80	door high = 95
PIM-6	door low = 96	door high = 111
PIM-7	door low = 112	door high = 127
