ALL-LOCK function
All keys on the operation panel are locked when the channel shift key is pressed for 3 sec. or more (unless CH-SELECT is set on 'PANEL').
To release the lock, press the channel shift key for 3 sec., or more, again.

Response time
The controllers
GD-C1
and
GD-C2
automatically select the most suitable signal processing method, according to the material and thickness of
the sensing object. Depending on the selected signal processing method, the response time is also automatically determined as either '5ms or
less', or '30ms or less'.
Further, when controller
GD-C3
is used, the response time is 5ms or less.
The response time of the controllers,
GD-C1
and
GD-C2
, can be confirmed by the following procedure.
Ԙ
ԙ
Press '0-ADJ. key' in RUN mode'.
The channel display shows an alphanumeric character that represents the re-
sponse time in the right.

GD-C2
can feed in the set level data into a PC or PLC memory using RS-232C serial communication and retrieve it whenever required.
In this case, the taught data should be stored in the prescribed channel.

Command
If the sent command is ineffective,
GD-C2
returns 'Not Available'.
All characters including send and response statements are based on ASCII code.
All commands used to communicate with
GD-C2
are classified into three groups: write command, read command, and others (ASCII coded data
communication).
Notes: 1)
2)
3)
The
GD
series automatically selects the most effective sensing process
according to the material and thickness of the object.
The process number ranges from '00 to 47' in decimal number system.
Both the one-sheet level data and the two-sheet level data are repre-
sented by decimal numbers from '0 to 4,095',
The data information, information on the presence of data, the sensing
mode, etc., is represented by decimal numbers from '00 to 63'.

Write command
Syntax: Statement + Numerical data + CR (ETX)
After the write command is sent, Statement + CR(ETX) is returned
by
GD-C2
to confirm the communication.
<Type of commands>
Note: Both the one-sheet level data and the two-sheet level data are represented
by decimal numbers from '0 to 4,095',
Note: Make sure to turn the power off when set the parameter DIP switch. When turn the power on, the set contents are reflected.
After setting, be sure to mount the protective cover.
