RS-232 Port
The CD 800 can be controlled by a host device/computer
through the RS-232 port.
The RS-232 connector is a 9-pin D female connector with
the following pin designations:
Pin Usage Function
1 — No connection
2 Tx Transmit data
3 Rx Receive data
4 — No connection
5 Gnd Ground
6 Contact closure Input 1 (See page 3-6.)
7 Contact closure Input 2
8 Contact closure Tally 1
9 Contact closure Tally 2
The RS-232 protocol is 9600 baud, 8-bit, 1 stop bit, and no
parity. For remote contact closure operation, see “Remote
Contact Closure” on page 3-6.
Host-to-CD 800 instructions
When the CD 800 receives a command and determines that
it is valid, it executes the command and sends a response to
the controlling (host) device. If the switcher determines
that the command is invalid, an error response is returned
to the host. All responses from the decoder to the host
begin and end with a carriage return and a line feed (CR/
LF).
Using the command/response table
The table on the next page lists the commands that the
CD 800 recognizes as valid, and the responses that are
returned to the host. The Command Description column
defines the command, describes the results of executing the
command, or displays the response. An example of each
command is shown to the right of the Command
Description column.
Time-out
A delay of 10 or more seconds between command sequence
characters causes a time-out. The command operation is
stopped, and there is no indication that a time-out occurred.
