■ Setting transmission parameters
Set transmission parameters when performing digital-transmission between the GC and
Chromatopac for the first time. (This is not required for each operation.)
1. Set transmission parameters for the GC
(1) Select “6. GC CONFIGURATION” on
the [FUNC] key screen and then select
“3. TRANSMISSION PARAMETER.”
(2) Set transmission parameters.
Protocol = LEVEL2
Baud rate (bps) = 9600
Stop bit = 1 bit
Parity = EVEN
(3) Press the [PF2] key (Apply).
Turning ON the power of the GC is not
necessary.
2. Set transmission parameters for the C-R8A
(1) Press the [CONFIG] key and then press the [T] key (T:TRS).
(2) Press the [ ↓ ] key until the STD2 Port (RS-232C) Setup screen appears.
(3) Set transmission parameters.
MODE = 12917 (Protocol LEVEL2, Stop bit 1 bit, Parity EVEN)
#No. = 8 (logical port number)
BPS = 9600 (baud rate)
(4) After completing setting, press the [EXIT] key and then press the [Y] key to save the
settings.
(5) After changing transmission parameters, reboot the C-R8A to enable the new settings.
■ Procedures to start digital transmission
After setting transmission parameters, start digital transmission.
1. Start digital transmission.
(1) Type “OPEN TRS 8” using the C-R8A keyboard and press the [Enter] key.
(2) The transmission port will open and transmission between the GC and C-R8A will start.
To turn OFF the power of the GC or Chromatopac after opening the transmission port, type “CLOSE
TRS 8” using the C-R8A keyboard and press the [Enter] key.
［PORT | MODE | #No. | BPS ］
STD2 | 12917 | 8 | 9600
