1.2 Serial (RS-232) Interface Functions and Specifications
Reception Function
You can specify the same settings as those specified by front panel key operations.
Receives output requests for setup data and error codes.
Transmission Function
Able to output setup data and the status byte.
Outputs error codes that have occurred.
Serial (RS-232) Interface Specifications
Electrical characteristics: Conforms to EIA-574 (9-pin EIA-232 (RS-232))
Connection: Point-to-point
Transmission mode: Full-duplex
Synchronization: Start-stop synchronization
Baud rate: 9600, 19200, 38400, 57600, or 115200
Start bit: Fixed to 1 bit
Data length: 7 or 8 bits
Parity: Even, odd, or no parity
Stop bits: 1 or 2 bits
Connector: D-sub 9 pin
Flow control: Select hardware handshaking using RS/CS or no flow
control
Switching between Remote and Local Mode
When Switching from Local to Remote Mode
The VB8300 switches to remote mode (SYSTem:KEYLock ON is also enabled) when it
receives a :COMMunicate:REMote ON command from a PC in local mode.
•All keys except SHIFT+KEYLOCK are disabled.
•Settings entered in local mode are retained even when the VB8300 switches to
remote mode.
When Switching from Remote to Local Mode
Pressing the SHIFT+KEYLOCK key when the VB8300 is in remote mode causes the
VB8300 to switch to local mode. However, this is void when the VB8300 has received a
“:COMMunicate:LOCKout ON” command from the PC (local lockout condition). VB8300
also switches to local mode when it receives a :COMMunicate:REMote OFF command
for the PC. However, if local lockout is enabled, an error occurs and the switch to local
mode is not possible.
•Key operations are enabled.
•Settings entered in remote mode are retained even when the VB8300 switches to
local mode.

1.3 Connection via the Serial (RS-232) Interface
When you connect the VB8300 to a PC, you must set the VB8300 so that the
handshaking method, baud rate, data format, and other parameters match those on the
PC.
For details on the settings, see the following pages. In addition, use an interface cable
that meets the specifications of the VB8300.

1.4 Combination of Handshaking Methods
When using the serial (RS-232) interface for transferring data, it is necessary for
equipment on both sides to agree on a set of rules to ensure the proper transfer of data.
The set of rules is called handshaking. Because there are various handshaking methods
that can be used between the VB8300 and the PC, you must make sure that the same
method is chosen by both the VB8300 and the PC.
You can choose either of the two methods in the table below.

Set CA (RTS) to
False when the
received data buffer
is 3/4th filled. Set to
True when the
received data buffer
becomes 1/4th filled.
OFF-OFF
Data Transmission Control
There is no handshaking between the VB8300 and the PC. The “X-OFF” and “X-ON”
signals are treated as data, and the CS signal is ignored.
Data Reception Control
There is no handshaking between the VB8300 and the PC.
CS-RS
Data Transmission Control
Hardware handshaking is performed between the VB8300 and the PC. When the CS
signal becomes False while sending data to the PC, the VB8300 stops the data
transmission. When the CS signal becomes True, the VB8300 resumes the data
transmission. The “X-OFF” and “X-ON” signals are treated as data.
Data Reception Control
Hardware handshaking is performed between the VB8300 and the PC.
