- * If the terminal mode start command is not executed, the terminal command is not accepted. In this case, "E10" is displayed on the LT 1610A/1611/1612A LED.
- * When LT 1610A/1611/1612A is busy, transmitted data is only stored in the reception buffer. After busy status is canceled, data stored in the buffer is executed, then 06h (ACK) code is returned.
5. CONSTRICTION OF TERMINAL COMMAND
This section describes construction of the terminal command. The terminal mode is executed by transmitting 8-bit data in serial format via the RS-232C interface.
Before executing the command, the system should be set to terminal mode. Refer to Section 4.2,."Starting RS-232C Terminal Mode" for detail.
Win → LT 16XX: Data described below are transmitted from the personal computer equipped with BS-232C serial port to the LT 16XX
- 02: STX (Start of text) Fixed data attached to first character of the terminal command.
- 2E: Terminal command, group ID Fixed data attached to second character of the terminal command.
- CC: Terminal command, individual ID Attached to third character of the terminal command.
- P1 to Pn: Command parameter
Parameters required for each terminal command Parameter data length depends on the individual ID
03: ETX (End of text) Fixed data attached to end of the terminal command.
Data "06h" is transmitted from the LT 16XX to the personal computer equipped with RS-232C serial port.
7. SETTING COMMANDS
7.1 Graphic Plane Clear Command [ 02 2E 0C 03 ]
Win ← LT 16XX 106h (ACK)
0C: Graphic plane clear command No parameter, command only
Function: This command is used to clear one of the graphic planes (*) displayed.
Note: There is no parameter to be set.
This command is effective when the quick pattern or quick address is set on. However, when the quick-registered plane is displayed, it is cleared by executing this command. Set quick mode again to display the plane.
This command only clears one of graphic planes displayed up front. Therefore, this command is ineffective for such patterns displayed by using eight graphic planes as natural-color patterns and gray scale. Patterns (e.g., color bars) drawn without a graphic plane cannot be cleared.
(*) Graphic plane:
Displays pattern numbers (i.e., 00h, 01h, 10h, 11h, 40h - 74h). The level can be varied with the "GR Level" of the "Signal" tab in the "Timing set" program. Lines, characters, and circles of special pattern A0h are drawn by using a graphic plane.
7.3 Direct Address Command [ 02 2E 21 - - 03 ]
Win LT 16XX 02 2E 21 MM XX 03
21: Direct address command
MM: Address mode 00h: ROM mode 01h: RAM mode XX: Address data (00 - 63h)
- Function: This command is used to directly set program addresses 00 through 63h (99 in decimal number) and ROM/RAM mode in binary format. Addresses exceeding "Begin" and "End" can be accepted.
- Note: When address data exceeds 99, "E10" is displayed on the LED, and the previous pattern is drawn. When the mode data is other than "00h" or "01h," "E10" is displayed on
the LED, and the previous pattern is displayed.
This setting remains effective until power is turned off. When the terminal mode ends and LT 16XX is operated without remote controller LT 1610-01 (sold separately), this mode depends on the setting of "DIP SW1-1"( ROM/RAM mode) located in the user ROM compartment.
Refer to Section 6.1.1, "Selecting Program Memory (ROM or RAM)" in the instruction manual supplied as a standard accessory for ROM and RAM modes.
7.5 BEGIN/END Address Setting Command [ 02 2E 21 - - 03 ]
- 23: BEGIN/END address setting command
- XX: BEGIN address (00 63h)
- YY: END address (00 63h)
Function: This command is used to set BEGIN/END address. The settable range is 0 to 63h (99 in decimal number).
Note: When "XX (BEGIN)" or "YY (END)" exceeds 63h (99 in decimal number), it is handled as error. "E10" is displayed on the LED and data is ignored. When "XX (BEGIN)" is larger than "YY (END)," it is handled as error.
"E10" is displayed on the LED and data is ignored.
When the address from "XX (BEGIN)" to "YY (END)" exceeds the address being executed, the address is set to "XX (BEGIN)" and pattern is drawn.
7.7 Comment Positioning Command [ 02 2E 30 - - 03 ]
to default value (63, 234). The display depends on the setting of "DIP SW1-2" located in the user ROM compartment.
Refer to Section 5.3, "Setting the Panel DIP Switches" in the instruction manual supplied as a standard accessory.
7.8 Comment Character Change Command [ 02 2E 31 - - 03 ]
31: Comment character change command
UU: Enter 0
CC: Comment character
Function: This command is used to change comment character.
Note: Comment display mode should be set ON before executing this command.
The comment characters are effective until the comment or address is changed.
Up to eight characters can be used. When the comment is less than eight characters, enter 20h (space) in the remaining portion. Figure 4 shows an example.
