OSDP address reassignment when migrating from MPA2C1 to MPA2C3 panel
Note: Below the description of the panels are MPA2C1 and MPA2C3. For MPA2C1 the
following part numbers can be filled in as well: MPA2C1-4, MPA1002U-MPS,
MPA1004U-MPS, MPA1002E-MPS and MPA1004E-MPS. For MPA2C3 the
following part numbers can be filled in as well: MPA2C3-4, MPA2MPSU, MPA4MPSU,
MPA2MPSE and MPA4MPSE.
When an MPA2C1 (first generation MPA2) is replaced by an equivalent MPA2C3
panel, then the OSDP addresses in the already installed readers are wrongly
addressed for the new MPA2C3 panel. The below table shows the old and new
addressing and functions of the OSDP readers.
Table 3-8 Reader function and different addresses when migrating panels
To make the installed readers compatible with the new MPA2C3 panel the
addresses of the installed OSDP readers must be edited by adding 1 to their cur-
rent address. Below the two possible procedures to edit the readers.
Option 1: Connect reader with highest address first.
