9-1. RS Command Format
This section presents the format of RS commands. A crosspoint switching command is shown in
the example below. When input is made to a serial control device using the commands in the
box, the VSF-600 returns a reply of either completed normally or abnormally.
CD Dest(3) Src(4) 1 CR+LF
This is the command issued from a serial command device. It is sent as ASCII code. The line
break character CR (0D)+LF (0A) should be always added at the end of the command.
Dest(3) Src(4)
This indicates that this parameter is sent using the number of bytes in parentheses. Dest is used
to set the channel number of the destination channel (output channel). To select channel 1,
“001” is set so that it becomes 3 bytes. Src is used to set the channel number of the source
channel (input channel). To select channel 1, “0001” is set so that it becomes 4 bytes.
The maximum value of the channel numbers for the destination channel and source channel is
128.
1
This indicates the level.
IMPORTANT
In the VSF-600, the level is fixed at 1. Be sure to always enter 1.
After the command is sent, a reply message is received.
If this command was executed normally, a reply of “OK” is sent, and if the command was not
executed properly due to some cause, a reply of “ER” is sent. The line break characters CR
(0D)+LF (0A) are also added at the end of these reply messages.
