PL7004 Kit
Rev F 21
3.5.4 AC Line Power Connection
AC line power connection to the probe interface is made at the AC inlet, which is a female IEC-320
connector. A line cord suitable for the type of AC outlet used, and consistent with local electrical codes, must
be obtained to mate with this connector. Minimum wire size recommended for the line cord is 1.5 mm² (16
AWG).
3.5.5 Interface Connectors
There are up to four types of connectors on the interface’s rear panel:
•
F/O RS-232 (for connection to FM7004 monitor)
•
RS-232
•
GPIB (IEEE-488)
•
USB
RS-232 and USB are serial interfaces. GPIB is a parallel interface. The basic specific command and response
sets are similar for each interface type on a particular model. Refer to specific interface type for operation.
3.6 INITIAL TURN-ON AND WARM-UP PROCEDURE
Operation is straightforward as described in prior sections of this manual.
After installation, turn on the Power switch on the probe interface. Observe the power on light. While
allowing a warm-up of about 10 seconds, recheck that all fiber optic cables are connected. Check the F/O
Status LED. Enable the laser power supply with the key switch. Press the laser on button once. Wait three
seconds. Observe that the green Laser on indicator stays lit. This indicates that the probe is responding.
To completely turn the probe kit off, turn the power switch to the off position. To maximize laser life, turn
laser off when not in use using key switch.
3.7 OPERATING PROTOCOLS
Operating protocols for the probe kit are described for three different electrical interfaces: RS-232, GPIB
(IEEE-488), and USB. For each type of electrical interface, there are two categories of protocol: NORMAL
and ERROR.
NORMAL protocol defines the operational protocol for use of the probe kit products in normal applications.
Commands are to the probe kit and Responses are from the probe kit. A command to the probe kit may result
in an ERROR response code. Error response codes are consistent with probe kit operation as needed. It is a
goal of the probe kit to provide a proper NORMAL response to each command
or a proper ERROR code in
response to each command. Error codes focus on the interface, and the first item reported is generally
sufficient. Identification of
internal probe errors is not included in the product firmware, since there are no
user serviceable items in the probe.
