3.2 Set-up 1838 Access Controller for PC Programming
The 1838 access controller come standard with a 3000 memory chip installed on the board. The smaller APB/memory chip no
longer exists on the NEW 1838 board. The NEW 1838 can be re-programmed to work with with OLDER existing 1830s series
telephone entry systems. The information below will assist you identifying chip specifications for older 1838 access controllers.
Before programming a NEW 1838 to operate with existing older 1830s, you must know the memory capacity and type of the
EEPROM chips that have been installed in the older units. This can be determined by inspecting
the small chip that has a tag listing the memory size on it and labeled APB if anti-pass back is
enabled. The memory size determines the number of residents, vendors, four-digit entry codes
and device codes that can be stored in the system. APB indicates that the chip set has anti-pass
back capability. The table shows the valid part numbers available with each memory level.
If you need to remove and replace chips, see Section 1.5 Memory Chip Replacement.
If you are going to re-program a NEW 1838 (less than 3000) to be used with existing OLDER
1830(s), Section 3.2.11 will need to be completed to MATCH the OLDER existing 1830(s).

Prior to using a PC to program this PC Programmable 1838 access controller with the DoorKing Remote
Account Manager for Windows software, section 3.2 factory settings MUST be reviewed or
re-programmed if necessary (most factory settings are typically desired). There is no need to re-program
these settings unless you want to change them. For easy reference, refer to the chart on page 28 that list
the various programming functions and their factory default settings. Section 3.2 can ONLY be
programmed from the 1838 Keypad. There is NO programming sequence in the Remote Account
Manager Software to program these features with.
This programming step sets the 1838 MASTER CODE. The master code is the four-digit number REQUIRED to gain access to
the 1838 memory. You need to know the master code prior to programming the 1838 with the PC, or to perform ANY of the
programming functions on the following pages. It MUST be programmed in from the 1838 keypad.
NO Factory setting - Each 1838 access controller’s master code MUST be unique.
See section 4.1 for more information about the master code switch.
Important Note: If you make a mistake while programming, press keys at the same time
to escape from programming no matter how much has been completed, then begin again at step 1.
1. Open the enclosure of the 1838 and turn the master code switch ON.
2. Enter a four-digit master code then press (beep).
3. Turn the master code switch OFF and close the enclosure.

Important Note: There is no way of retrieving the master code after it has been
programmed in. If you forget it, you will have to program in a new one but all other
previously programmed information will remain intact.
