RS-232C Adjustment Mode
1.3 ID Assignment
After connecting to a computer, the PC can assign an ID for each plasma display panel.
Commands: <IDC> (ID CLEAR) ........ Clears the assigned ID
<IDS> (ID SET) ............. Assigns an ID
IDS is only effective when an ID is not assigned.
Also, IDs are set starting from the set closest to the PC.
Example: Case of 4 displays (assigning IDs with the PC for the first time)
Connect each unit as shown below.
Refer to section 5.5.4, “Combination Connection" (pg. 219).
By sending RS-232C commands in this order, it is possible to assign an ID for each unit.
Units for which an ID has been set can only receive commands with an ID attached. Attach an ID before sending a
command.
ID characters can include 0 - 9 and A - F (there is no distinction between upper and lower case letters).
.
An ∗ (asterisk) can be used as follows:
<
∗∗IDC>: Clear the IDs assigned for all sets
< ∗1AJY>: Only a set with the second digit as 1 enters the RS-232C adjustment mode
<2 ∗IN1>: Only input of a set with the first digit as 2 is set to INPUT1
Precautions when assigning IDs
Units that were connected after a set whose ID was cleared cannot be operated with RS-232C commands.
After assigning a setting as shown in the figure above and <
∗∗AJY> = <∗∗IDC> is performed, the IDs for all the sets
from Set #1 to Set #4 are cleared. Only the one set (Set #1) that is directly connected to the PC can be controlled.
Furthermore, by performing <
∗∗ AJY> = <01 IDS>, it again becomes possible to control the second set (Set #2). By
setting IDs in the same way for the other sets, it again becomes possible to control the sets connected in succession.
Note
When the IDs are set and one or both of the IDs before a command are sent from the PC as a
∗, there is no echo
back. When sending more commands, wait 6 seconds before sending the next command.
Example) When ∗∗OOO and ∗1OOO or 1∗OOO (OOO is the command) are sent from the PC, operation is performed
but there is no echo back.
