If this connection scheme doesn’t work with your printer, it is nearly always a matter of
changing one wire on the 25 pin printer connector. Move the wire from pin #20 to pin #5.
It is also possible to connect the DK-26 to a computer which is set to emulate a terminal. In
this way, the data can be captured and manipulated or viewed later. For IBM PC type
computers, the connections are as follows: (note the computer input is a 9 pin cable (DB-9F)
DK-26 Connector (9
pins)
Signal Name Computer Serial Input (9
pins)
Pin #3 Serial Data Out Pin #2
Pin #5 Ground Pin #5
Pin #8 Clear to Send Pin #4
4.3 ENTERING THE DATE AND TIME
With the unit in program mode, enter the command 60 immediately followed by two digits
each for the month, the day, the year, the hour and the minutes. Note that the 24 hour
format is used for entering and printing out the hour of the day. Don’t press the bell key to
terminate the entry. Since the entry is of an exact defined length, it terminates itself.
A sample programming entry would be 600215981820 (February 15, 1998 at 6:20 PM)
The printer will echo this entry by printing the message: 02/15/98 18:20
Note that in America, the convention is to print the month before the day but in most foreign
countries, the day appears before the month. This “international” format is also supported by
the expanded DK-26. Use the command 61 immediately followed by two digits each for the
day, the month, the year, the hour and the minutes. Note that the 24 hour format is used for
entering the hour of the day.
A sample “international” entry would be 611502981820 (February 15, 1998 at 6:20 PM)
4.4 PRINTING OUT A LIST OF CODES
When in program mode, you can always print out a list of all codes active in memory whose use
will open the door. Simply enter the command 64. This is valuable as with many codes in
use, questions can sometimes arise over what codes are actually in memory.
4.5 ENABLING AND DISABLING THE PRINTER
In many cases you won’t want the printer operating all the time. For example, you might want
to keep records of who entered the facility only at night or use the printer only to record
programming changes. Of course, the printer itself can be turned on and off but printing
capability can also be enabled and disabled from the DK-26 in two different ways.
First, by entering command 53 while in program mode, printing is disabled. Entering 52 re-
enables it (enabled printer is the default condition.)
Second, terminal “PT” on the expansion board permits disabling and enabling the printer from an
external switch. This is useful to set up time of day printer control from the use of an external
timer such as Securitron’s model DT-7. When terminal PT is unconnected. the printer is
enabled. When it is connected to the source of +V which is powering the DK-26, the
printer is disabled.
4.6 MULTIPLE UNITS CONNECTED TO ONE PRINTER
In installations that have more than one DK-26 unit, it can make sense to “multiplex” them into
a single printer. This not only saves the expense of multiple printers but produces a more
concise printer record of door use by consolidating the information on a single print-out. The
expanded DK-26 system allows for up to ten units to connect to a single printer.
Two issues come into play. First you need to purchase a commercially available item called a
“buffer box”. This allows connecting in multiple serial cables coming from each DK-26
expansion board. The buffer box then has a single output cable which goes to the printer. All
