CI Systems SR-800R
6.1.3 Transferred Data Format
RS232: Each byte will be transferred serially as follows:
• 1 START bit.
• 8 data bits (transferred data), LSB (D0) first.
• 1 STOP bit.
• No parity.
Ethernet: Data is sent in packets. The protocol implemented is based on TC/PIP.
The SR-800R uses a built-in server port of 5200 to respond to client requests. For
customers interested in using Ethernet, CI can provide a sample program
demonstrating the operation of the protocol.
GPIB: DATA is sent in a Byte-Wide bus via IEEE-488 Control Connections.
6.1.4 Naming Bits
The Most Significant Bit (MSB) in each byte is named D7.
6.1.5 Command Message Structure
Each Command contains a CommandBody and a CommandOperandBody:
The CommandBody and CommandOperandBody are separated by a Space
ASCII Text Character, 0x20 Hex, symbolized by Space
sign.
The CommandOperandBody contains the command operands. There may be
from no operands to a few operands in the CommandOperandBody. Each Operand
is separated by a Comma ASCII Text Character, 0x2C Hex. This is symbolized
by the Comma
sign.
Commands are case insensitive unless otherwise noted.
