Serial Interface Specification

Transfer Specification

1. Transmission Speed: initial setting value is 19200

2. Transmission speed can be changed by hotel mode.

Connection

The Designated RS-232C serial cable that is provided with the LCD

monitor must be used for a connection to a computer and LCD

monitor

Notes for communication

The monitor command is defined by one command/one line that

starts with “C” and ends with carriage return (0x0D)

There are two types of commands:

Functional Execution Command e.g. Co5[CR] (table on page 12)

Status Read Commands e.g “CR0 [CR] (see table on page 12)

Setting the monitor address in RS232 mode

To Access hotel mode press the green button on the remote control

and hold for 5 seconds. A new screen will appear.

Each monitor can have a specific Address, for example 007, which

helps command that monitor individually and will not effect other

monitors connected to a controlling PC.

Address format command

The addressing format command is used for operating multiple

monitor sets from a single PC via the RS232C command line. If you

set your monitor address to ‘000’, it will never respond to any

addressing command from the PC.

If the address from the PC is ‘FFF’, all monitor sets will execute the

command.

The Address format command is defined by one command, one line

which starts with ‘A’ and ends with carriage return.(0 x0D)

The Monitor starts to decode when it receives a carriage return

(0x0D).

An address is added at the top of a control command (same as a

address command).

Example:

Functional execution command:

“A001C05” [CR] means address is 001 and the control command is

C05.

Status read command

“A001CR0”[CR] means address is 001 and command is CR0.

The monitor can set its own address in the hotel option menu

(above). The address range is 000 - 999, the default address will be

000.

The baud rate indicates the unit for transfer speed of data

from the PC to the monitor sets.

■ Switching into/from standby mode

The Standby mode is used for switching the LCD monitor off for

short periods of time. In standby mode the monitor is switched

off but is still receiving mains power.

● To turn the monitor into standby mode, press the

button.

The blue power indicator illuminates more brightly.

● To turn the monitor ON from standby mode, press any of the

following buttons:

0-9 buttons.

■ Use of Audio Output Jacks

The audio monitor out sockets on the rear of the set provide a fixed

level audio output for reproducing sound via your audio equipment.
