The pL-Tray / pL-Fiber Tray is designed to power up to 10 picoLinks within a 1
RU frame. The pL-Tray / pL-Fiber Tray provides full power redundancy. Each
power supply provides 40 W and supports a fully loaded frame.
The pL-Tray provides a simple yet effective way to manage the different sizes
and formats of electrical picolink modules.
When installed in a pL-Fiber Tray, the picoLink fiber converters become an
electrical-to-optical / optical-to-electrical patch bay. The SDI electrical end of the
picoLink converters exits out the rear where coaxial cabling may be neatly routed
and attached.
1.2 Features
• Supports up to 10 picoLink and/or 5 dual picoLink modules
• Redundant power supply
• Power supply status: each power supply has a two-colour status indicator in
the front indicating normal operation or failure mode
•Creates a fiber to/from electrical “patchfield”

3.1 Unpacking
Make sure the following items have been shipped with your pL-Tray / pL-Fiber
Tray. If any of the following items are missing, contact your distributor or Miranda
Technologies Inc.
• pL-Tray or pL-Fiber Tray for fiber optic picoLink Series Products
• 2 AC power cords
• 1 designator strip (pL-Fiber Tray only)
• 20 hook-and-loop fastener disks (pL-Tray only)
• This manual
3.2 Rack Mount Installation
The pL-Tray / pL-Fiber Tray has been designed to facilitate rack installation by
providing removable bracket and two rack-mounting positions. Use industry
standard screws specified by your rack manufacturer. Miranda suggests using
nylon washers to prevent damaging the rack brackets. Alternatively, side
mounting holes have been provided to install standard 0.25” thick rack slides
(such as General Devices model CC-3700).
3.3 Designator Strip Installation for pL-Fiber Tray
A designator strip is supplied to identify the fiber optic inputs/outputs at the front
of the tray. Remove the peel-off adhesive backing and apply below the row of
opening at the front of the picolink frame, as shown on picture below.

3.4 Installing Fiber Optic picoLinks in the pL-Fiber Tray
Follow these steps to properly power fiber optic picoLink products.
1. Install AC power cords for PS-1 and PS-2. For full redundancy, plug each
cord into a different AC circuit.
2. Install up to 10 fiber optic picoLink products as shown in Figure 3.2. Insert the
fiber optic picolink from the rear into the picolink frame and push until the
connector spring bracket snaps in place. Connect the DC plug of each
picolink into a DC power connector of the pL-Fiber Tray power frame.
3. To remove a DC plug from the DC power connector, simply depress the
PUSH tab while pulling the DC plug.
4. After installing BNC cables on the fiber optic picolinks, insert plastic ties
through the lances on power frame and attach cables to secure in place.
Figure 3.2 Fiber optic picolink installation
3.5 Installing Electrical picoLinks in the pL-Tray
Follow these steps to properly power electrical picoLink products.
1. Install AC power cords for PS-1 and PS-2. For full redundancy, plug
each cord into a different AC circuit.
2. Prepare each picoLink as shown in figure 3.3. Peel off the backing tape
of two hook-and-loop fastener disks and place them at each end of the
underside of the picoLink module. Since the disks cover part of the label,
make sure that you place the disks on the opposite side from the label
that identifies the connectors.

3. Install up to 10 picoLink products as shown in Figure 3.4. Press the
picoLinks firmly against the hook-and-loop fastener bands of the pLTray. If desired you may use plastic ties through the openings to secure
the picoLink modules. Make sure that the DC plug of each picoLink is
firmly installed in a DC power connector of the pL-Tray power frame.
4. To remove a DC plug from the DC power connector, simply depress the
PUSH tab while carefully pulling the DC plug.
5. After installing input and output cables on the picoLink modules, insert
plastic ties through the lances on power frame and attach cables to
secure in place.

3.6 DC Cable Construction
If you wish to power a picoLink from a distance, you will have to make an
extension cable with female and male ends. The wire caliber must be large
enough to limit the voltage drop to less than 100mV. Figure 3.5 describes the
female DC connector pin-out as viewed from the pL-Fiber Tray power frame.
WARNING
Damage will occur to picoLink if the power supply adapter polarities are not
respected.

4.2 Replacing the Defective Power Supply
After you have located the defective internal power supply, perform the following
steps to replace it.
1. Make sure both AC power cords have been removed.
2. Remove the AC and DC cables from the defective power supply. Refer to
Figure 4.2.
3. Remove the defective power supply’s mounting screws.
4. Install the new power supply and reinsert the cables.
5. You are now ready to perform the power supply adjustment. Refer to section
4.3, Power Supply Adjustment.
4.3 Power Supply Adjustment
After you have replaced the defective internal power supply, perform the
following steps to adjust its voltage level.
1. Disconnect the DC plug of all picoLink units in the Tray.
2. Install an AC power cord for the replacement power supply. Make sure the
front status LED for this power supply turns on.
3. Using a voltmeter, probe the red (+) and gray (- or ground) wires of the DC
cable. Now, using a small technician’s screwdriver, adjust the power supply’s
potentiometer until the voltmeter reads 5.4 VDC.
4. Install a second AC power cord. Check the front status LED to be sure this
power supply turns on.
5. Repeat step 3 for the second power supply.
6. Replace the top cover.
