B. Optional LOG BUS Wiring
The C-4000 transmits 1200 baud ASCII data from the
LOG BUS screw terminals. Log Bus data is sent each
time there is an entry point event, and includes: an
entry point ID number, if the entry was valid or non-
valid, the facility code, and the card number (or key-
pad entry code).
Pin 2
(Receive Data)
If the RS-232 input of a PC, printer, etc. is capable of receiving TTL level
RS-232 signals, then the LOG BUS can be wired directly into the RS-232
"Receive Data" and "Signal Ground" pins to receive ASCII data. Windows
"Hyper-Terminal" can be used to receive the data on a PC. Use the set-
tings in the chart at the right:
C. Optional PC Programming Wiring
Programming the C-4000 can be done with a Touch Tone phone or by using a PC. If using PC programming, use a
serial port connection as shown below and visit www.vikingelectronics.com to download free C-4000 programming
software. Compatible with any Windows based PC running Windows 98 or higher, the software allows programming of
all C-4000 parameters using the computer.
Note: After PC programming is accomplished, it is recommended to not use Touch Tone programming to make
changes, as these changes will not show in the PC programming data base. If Touch Tone programming is used to
make changes, be sure to make those same changes in the PC programming data base to keep it accurate.
