(Note)
When the following commands are sent, a controller should wait for specified period after receiving the reply command before sending the next command.

• Power On, Power Off: 15 seconds
• Input Change: 10 seconds

Communication Format

The command packet consists of four parts, Header, Message, Check code and Delimiter.
Note: Don’t add extra data (Example: padding data) after Delimiter.
Recommended sequence of a typical procedure to control a monitor is as follows,[A controller and a monitor, two-way communication composition figure]

• For the general command (see the part “6.2. Operation Code (OP code) Table”)
  • The controller sends command to get a value from the monitor that you want to change.
  • The monitor replies a current value of the requested item.
  • The controller sends commands to set an adjusted value.
  • The monitor replies to the controller for confirmation.
  • The controller sends command to get a value for confirmation.
  • The monitor replies an adjusted value.
• For the special command (see the part 7, 8)
  • The control does not suitable for above fixed protocol; use the proper command for each control. Please refer section 7 and 8.
  • The monitor replies a proper message defined for each control.

Header block format (fixed length)

• 1stbyte) SOH: Start of Header
  ASCII SOH (01h)

• 2ndbyte) Reserved: Reserved for future extensions. On this monitor, it must be ASCII ‘0’(30h).

• 3rdbyte) Destination: Destination equipment ID. (Receiver) Specify a commands receiver’s address.
  The controller sets the “MONITOR ID” of the monitor controlled in here.
  On the reply, the monitor sets ‘0’ (30h), always.
  “MONITOR ID” to “Destination Address” conversion table is as follows,Monitor ID| Destination Address
  ---|---
  1| 41h(‘A’)
  ALL| 2Ah(‘*’)

MONITOR ID of PN-LC862/LC752/LC652 are “1” (Fixed).
Therefore PN-LC862/LC752/LC652 should accept, only when 3rd Byte is 41h or 2Ah.

• 4thbyte) Source: Source equipment ID. (Sender) Specify a sender address.
  The controller must be ‘0’ (30h).
  On the reply, the monitor sets the own MONITOR ID in here.

• 5thbyte) Message Type: (Case sensitive.)
  Refer to section 4.2 “Message block format” for more details. ASCII ‘A’ (41h): Command. ASCII ‘B’ (42h): Command reply. ASCII ‘C’ (43h): Get current parameter from a monitor.
  ASCII ‘D’ (44h): “Get parameter” reply. ASCII ‘E’ (45h): Set parameter.
  ASCII ‘F’ (46h): “Set parameter” reply.

• 6th -7th bytes) Message Length:
  Specify the length of the message (that follows the header) from STX to ETX.
  This length includes STX and ETX.
  The byte data must be encoded to ASCII characters.
  Ex.) The byte data 3Ah must be encoded to ASCII characters ‘3’ and ‘A’ (33h and 41h).
  The byte data 0Bh must be encoded to ASCII characters ‘0’ and ‘B’ (30h and 42h).

Message block format

Message block format” is allied to the “Message Type” in the “Header”.
Refer to the section 4.1 “Header block format” for more detail.

1. Get current parameter
   The controller sends this message when you want to get the status of the monitor.
   For the status that you want to get, specify the “OP code page” and “OP code”, refer to “6.2 Operation code table”.
   “Message format” of the “Get current parameter” is as follows,STX| OP code page| OP code| ETX
   ---|---|---|---
   Hi| Lo| Hi| Lo

Refer to section 5.1 “Get current parameter from a monitor.” for more details.

2. Get Parameter reply
   The monitor will reply with the status of the requested item specified by the controller in the “Get parameter message”.
   “Message format” of the “Get parameter reply” is as follows,STX| Result| OP code page| OP code| Type| Max value| Current Value| ETX
   ---|---|---|---|---|---|---|---
   Hi| Lo| Hi| Lo| Hi| Lo| Hi| Lo| MSB|  |  | LSB| MSB|  |  | LSB

Refer to section 5.2 “Get parameter reply” for more details.

3. Set parameter

   ---|---|---|---|---
   Hi| Lo| Hi| Lo| MSB|  |  | LSB

Refer to section 5.3 “Set parameter” for more details.

4. Set Parameter reply
   The monitor replies with this message for a confirmation of the “Set parameter message”.
   Message format of the “Set parameter reply” is as follows,STX| Result| OP code page| OP code| Type| Max value| Requested setting Value| ETX
   ---|---|---|---|---|---|---|---
   Hi| Lo| Hi| Lo| Hi| Lo| Hi| Lo| MSB|  |  | LSB| MSB|  |  | LSB|

Refer to section 5.4 “Set parameter reply” for more details.

5. Command
   “Command message” format depends on each command. Usually, this “command message” is used for some non-slider controls and some special operations, such as “Save current settings”, “Get timing report”, “power control”, etc. Refer to section 5.5 “Commands message” for more details.

6. Command reply
   The monitor replies to a query from the controller. “Command reply message” format depends on each command.
   Refer to section 5.5 “Commands message” for more details.

Check code

Check code is the Block Check Code (BCC) between the Header and the End of Message except SOH.

Following is an example of a Check code (BCC) calculation.

Check code (BCC) D17 = D1 xor D2 xor D3 xor … xor D14 xor D15 xor D16
= 30h xor 41h xor 30h xor 45h xor 30h xor 41h
xor 02h xor 30h xor 30h xor 31h xor 30h xor 30h
xor 30h xor 36h xor 34h xor 03h
= 77h

Delimiter

Packet delimiter code; ASCII CR(0Dh).
