Command Structure
The Command Structure is binary coded with three consecutive 8-bit bytes. Synchronization is achieved by a
break in the transmission of more than three byte times. The first five bit of each command specifies the address
of the selected projector.
The 16 hardware addresses are 0-F (hex).
The address 1F (hex) is a global address that all connected projectors will accept. Several projectors can be
combined in a group by assigning them a special group address of 10 - 19 hex with a software command. Note,
global or group addresses are separate from the position that is selected on the address switch.
Three 8-bit bytes:
AAAAA MM 1 CCCC XXXD XXXXXXXD
1. Byte 2. Byte 3. Byte
AAAAA address of projector
MM selects command mode
CCCC commands depending on selected mode
XXXX XXXX XXX commands or information depending on selected mode
An example of command modes is:
- parameter mode 00
- set/reset mode 01
- direct mode 10
- status request mode 11 In this mode, the projector returns (10 bit) data.
This mode can be used for diagnostics purposes.
Details can be obtained from special marketing literature.
