Gilderfluke&Co DMX-512 Input Servo Motor Controller - Manual (Page 18)

the Eprom has been protected and warn you that you can no longer make
any changes. Configuration changes can be re-enabled at any time by
moving the jumper back to the ‘Enabled’ position.
Use the space bar or ape key if you want to keep a hard
copy printout of the current configuration of the SER-DMX while saving the
print in the modem program. This file can then be printed out at any time.
a) Card Serial Address: This command is used to set the address that
this card will be respond to on the RS-422 Serial port. Only one card
at a time can use each address. This means that if you are configur-
ing several cards, you may need to plug each one in one at a time
and set each of them to unique addresses. After they are addressed,
you can plug them all in at the same time and talk to them freely.
b) First Output Address: This command is used to set the SER-DMX to a
DMX-512 address. The address for each output is shown in the 'out-
put address' column. If twelve bit resolution has been selected, the
SER-DMX won’t allow you to address it at any ‘illegal’ # twelve bit ad-
dress.
c) DMX Rx Checksum: This toggle is used to enable and disable the
error checking in data received through the DMX-512 data input.
Without it, the SER-DMX won't be able to recognize errors in the in-
coming data, and may update the outputs with this bad data. It
should be left ON whenever running from a PC•MACs or other DMX-
512 source that supports this checksum.
g) Numbering System: This toggle is used to select between
HEXadecimal, Decimal, Percentage or ‘Pulse width’ numbering sys-
tems for display and entries. When percentage or ‘pulse width’ are
selected, all entries are still made in Decimal numbers.
h) VT-52 Compatible Display: When this toggle is enabled, the SER-
DMX will use special escape sequences to clear the screen
(ape 'E'), clear the current line (ape 'l'), or position the
cursor (ape 'Y' ROW COLUMN). When disabled, the SER-DMX
has to redraw the entire screen to change any value, so it can save
a good deal of screen redraw time if you have a compatible display.
i) Twelve Bit Resolution: When toggled ON, the resolution used for all
ServoMotor outputs will be twelve bits. This works out to a resolution of
one part in 4096. If you are using twelve bit resolution ServoMotor
outputs, you must carefully account for the locations and number of
output channels you are using. Each twelve bit resolution input takes
1-1/2 eight bit channels. The SER-DMX won’t let you set the first ad-
dress for a twelve bit servo output to any address that can be evenly
divided by three (0, 3, 6, 9, etc.). This is because it uses these bytes
