SERIAL IMPLEMENTATION OVERVIEW
SERIAL ROTARY DIAL SETTING AND CABLE PIN-OUT
TASCAM's AV-452 has a serial port capable of
operating in standard RS-232, RS-422 or RS-485
protocols which offers access to most switches and
indicator status on the AV-452. The AV-452 saves
resources on recursive scanning with a "query all"
command and by generating status replies on status
changes. An additional RS-232 command allows IR
strings to be learned for projector control, outlined
separately in: AV-452_IR_PRG.pdf.
Settings and Voltages
Note: The rotary control and most dip switches are only
scanned at power-up. You will need to turn the AV-452 off
and back on for any changes to take effect.
Under the security panel, there is a rotary dial that
determines the machine ID (address). This allows multiple
AV-452 machines to be connected to a single serial line and
still be addressed individually. If you are not using multiple
machines, this should probably be set to "1".
The RS-422 and RS-485 operation follows normal
specifications. However, RS-232 operation is a modification
of the RS-422 port. It operates at 0-4.5V, rather than
±9V.
This will operate normally with most equipment, such as old
control systems or PC computers. If you have trouble with
RS-232, try switching to RS-422 if you can to see if that
solves the problem.
