Recommended Installation Procedure
!
!
Please read and observe the instructions and guidelines in Section “Safety and Precautions” (page 21)
prior to installation. Failure to follow these instructions and guidelines may cause personal injury and/or
damage to the equipment.
1. If installing a VIPET fitted with VIPET-PSU-24V PSU with Earth Lift switch, ensure that the Earth Lift
switch is set to the correct position.

EARTH LIFT
!
!
Normally set to grounded position. It must only be set to ground-lift position if a +ve
ground battery supply is used.
2. Fit the VIPET unit to a 19-inch standard equipment rack on supporting rails, and secure the unit in
position using the fixing screws.

• Ensure that there is at least 1U of ventilated space between the unit and any source of heat
(e.g. V400 amplifier mainframes).
• The rail supporting the right side of the VIPET (viewed from the front) must not obstruct the
ventilation holes on the unit's bottom side.

3. If using the VIPET-SERIAL-4 (SeaLINK 2403), install the unit as described bellow.
a. Remove the unit’s feet.
b. Remove 3 screws at the bottom of the unit. These screws will be used to fix the unit to the
shelf.
The shelf which is supplied for mounting the VIPET-SERIAL-4 interface supports two units. The
screws to be removed depend on the unit’s position on the shelf.
The positions of the screws to be removed are marked with Xon the next drawing.
c. Position the unit on the shelf.

VIPET-SERIAL-4
This is a USB RS232/485 interface (SeaLINK 2403).
Each SeaLINK 2403 has 4 serial ports.
RS485 cable length: up to 1200m
RS485 data rate: up to 921.6 kbps
USB Connection: USB type B connector
Serial Connection: 9-WD (DB9) male connector
Dimensions: 179mm (L) x 135mm (W) x 38.1mm (H)
Rack installation shelf: for standard 19-inch rack, supports up to
two SeaLINK 2403 units
Serial and USB activity LEDs:
SERIAL 4SERIAL 3SERIAL 1 SERIAL 2USB
Although each port can be individually configured for RS232/422/485 by setting DIP switches inside the unit,
the unit is supplied configured for RS485. This configuration should not be changed as the VIPET is
configured for RS485 operation only.
