Usage:
Command Syntax: [:ROUTe]:[LAYer<layer>]:CHANnel <channel_list>
Where:
com_port=9
OUTPUT com_port; "OPEN RS232 COM"
[:ROUTe]:[LAYer]:CHANnel
The [:ROUTe]:[LAYer]:CHANnel command configures the channel connec-
tions. In the command syntax, the keyword "LAYer" refers to a switch layer. A
switch layer is a switch matrix of "A" ports and "B" ports. Normal lightwave
switches have only one layer installed. Special ordered instruments may have
multiple switch layers installed. If the front and rear panels show more than
one set of "A" ports and "B" ports, the instrument has multiple switch layers.
Standard lightwave switches do not require that the <layer> argument be
specified as shown in the command syntax. If no layer is specified, it defaults
to layer 1. The minimum layer number is always 1.
The minimum channel number is either 0 or 1, depending on whether the port
has an "OFF" position. The maximum number of layers and channels is depen-
dent on the switch configuration. If the command parameters are outside the
permitted range for the switch configuration, the switch position is not
changed and an error is generated.
The [:ROUTe]:[LAYer]:CHANnel query returns the current port settings for the
specified layer. If no layer is specified, the default value is layer 1.
On Option 002 dual input instruments, any light on an
unselected "A" channel will likely be output on one of the
unselected "B" channels.
On Option 002 dual input instruments, any light on an
unselected "B" channel will likely be output on an unselected
"A" channel.
To avoid exposure to light energy, always cover all unused channels.
GPIB and RS-232
<layer> a positive integer (NR1). Set to 1 if the instrument does not have
multiple layers.
<channel list> = A<channel>|B<channel>|A<channel>,B<channel>
<channel> = a non-negative integer (NR1) | OFF
