IC6 Operating Manual
Chapter 10
Remote Communications
10.1 Remote Communication Configuration Overview
This IC6 can be remotely controlled, programmed or interrogated through remote
communications and the use of a remote command set. The IC6 will respond to
messages that contain these commands. It will accept and operate on messages
one at a time. It will respond to each command by carrying out valid operations
and/or returning a message to the sender.
HINT: To reduce communications overhead, multiple commands may be
combined into one command string as described at Command Packet
(Host to IC6 Message) on page 10-6
A host/server relationship is established in remote communications. The IC6, as
server, responds to the remote host’s commands.
10.2 Physical Connections
You may choose to use one of two types of data communications hardware ports.
 Standard equipment includes a bit serial RS-232C port.
 Optionally, a TCP/IP port may be added.
Both RS-232C and TCP/IP ports can be used simultaneously.
Both the host and server must have the same form of communications equipment
and complementary set up. For serial communications, baud rates must match and
so must the data word format.
The word format for bit serial lines (RS-232C) is comprised of ten signal bits; eight
data bits, one start bit, one stop bit and no parity. The eight data bits comprise a
byte of information or character whose ASCII value ranges from 0 to 255.
