*NOTE: The maximum VDC draw denotes a power up condition when the
DC converter starts. Typical duration is 15-30 mS. Contact factory for
current draw at supply voltages other than + 12V and pin connection J2
POWER UP CONDITION
Immediately upon power up the following is set:
The module is in the text mode.
The screen will have a message printed as follows:
This message indicates the hardware test has passed
successfully. The "mm-dd-yy" indicates the date the
firmware was released.

Power up RESET cycle on display module takes approxi-
mately 250 mS to complete. It is suggested the user wait for
that time period to elapse before entering data.
PARALLEL INTERFACE
J2, PARALLEL DATA CONNECTOR.
Mates with 3M Tyco AMP 746285-6, 26 pin, IDC connector.
NOTE: PAR should be jumper selected on jumper block W1
for proper parallel interface operation.
Once data write is complete, BUSY signal is output. BUSY
signal = "1" during data disposition and while the communi-
cation buffer is full.
DATA WRITE: When WR changes from "0" to "1" while
US = "0" and RD = "1", data is latched.
DATA READ: When RD = "0" while US = "0". WR = "1", and
DP = “1”, data may be read by the host.
Mates to Tyco AMP *1 - 480424 - 0 housing (1 required)
NOTE: Input load is one 74 HCT type input with 4.7k to V
Outputs are 74 HC type.

DESCRIPTION
Data written to and read from the display unit through an 8 bit
bi-directional data bus.
Write data on low to high transmit.
Read data while low.
Not connected.
Reset display to power-up condition when low, operate while high.
Read and Write commands only influence display while US is low.
Blank display while BL is low but maintain cursor and data.
Display at full brightness when high, or half brightness when low.
When BUSY is high, no further data or commands should be given.
Common to both power supply input and host data interface.
Data is ready to be read when the DATA PRESENT signal is high.
