2. Installing the PIM-485-16-TD-NXT
2.1 Configuring the PIM-485-16-TD-NXT to Emulate DR42xx DigiReaders
The Schlage Configuration & Demonstration Tool (CDT, version 1.4 or higher) must be used to
configure each PIM-485-16-TD-NXT to emulate the desired number and address of DR42xx
DigiReaders.
The PIM-485-16-TD-NXT must be connected to the PC running the CDT using a serial connection
(either RS485 or RS232).
Once the PIM-485-16-TD-NXT is connected to the PC and the CDT is running, the Addresses tab on the
CDT’s PIM panel is used to configure the PIM-485-16-TD-NXT’s emulation addresses. There are four
fields on the Addresses tab: Unique, Addr Lo, Addr Hi, & MIRO. The Unique field shows the PIM-485-
16-TD-NXT unique address and should never be changed without instructions from Schlage Technical
Support. The Addr Lo indicates the lowest device address that the PIM-485-16-TD-NXT will emulate
and Addr Hi indicates the highest. The MIRO indicates which group of 8 the device will be in. (The
MIRO number will increment automatically when the number of linked devices is greater than 8.) Table
2-1 shows the allowable range of values for the Addr Lo, Addr Hi, & MIRO fields on the CDT Addresses
tab.
PIM Model Star Model Addr Lo Addr Hi MIRO
PIMx-485-16-NEX I 0-15 0-15 2-9
PIMx-485-16-NEX II 0-15 0-15 2-17
Table 2-1 – CDT Addr Lo, Addr Hi, & MIRO Fields Range of Values
After setting the Addr Lo & Addr Hi fields to the desired values, click the Set button to send these values
to the PIMx-485-x-NEX.
Rules for setting Addr Lo & Addr Hi:
♦ Addr Hi must always be equal to or greater than Addr Lo
♦ For multiple PIM-485-16-TD-NXT’s on the same S-NET there cannot be any address
overlap, in other words on the same S-NET there can be only one PIM-485-16-TD-NXT
emulating a specific DR42xx DigiReaders address.
♦ The DR42xx DigiReader addresses emulated by a PIM-x-485-x-NEX must be consecutive.
♦ A MIRO number must be unique to one PIM. While one PIM can emulate two MIRO’s, one
MIRO cannot be emulated by more than one PIM
♦ The ADDR LO and ADDR HI set the DR42XX DigiReaders addresses. This address along
with the MIRO number fixes the addressing of the Door Position Switch, Request to Exit,
and Output Relay as shown in Table 2-2, below.
