To set a unit whose front panel address is set to 15 to channel 07 with Local Lockout  send the
following string:

m;15071CR

To request a status report from the unit send the following string:

m;15staCR

The unit will transmit back its address, current channel setting, Local Lockout condition and baud
rate . The returned status will appear as shown below.

 Device Address    Current Channel     Local Lockout     Baud Rate
 15                07                  On                9600

Operational Considerations

For optimum operation utilize the patchcords that are supplied with the instrument. These patchcords
are constructed with the same fiber that is used inside the unit. The use of fibers with different core
diameters and numerical apertures will reduce the throughput. Also these patchcords are polished
with a domed endface in order to minimize etalon interface effects.

Always keep the fiber endfaces clean. They may be cleaned with a lint free cloth and alcohol. The
unit is supplied with specialized swabs in order to clean the female fiber optic connectors on the
back panel. If throughput is reduced on any one channel, clean all fiber endfaces.

Do not bend the fiber patchcords with less than a three inch bend radius. To do so may fracture the
fiber internally, especially if left in that state for an extended period of time.
