DigitalFlow™ XGF868i Startup Guide

1.7.2.2

Local or Remote Electronics Enclosure with Remote Preamplifiers

IMPORTANT:

The cable lengths for a given pair of transducers, including the preamplifier-to-electronics enclosure 

cables, must be equal to within ±4 in. (10 cm) of each other.

Note:

A dual preamplifier is typically used in these installations, and you must note the labeled upstream and 

downstream connections on the preamplifier. Be sure to connect the upstream transducer to the upstream 

connection on the preamplifier and in the XGF868i electronics enclosure. Follow the same procedure for the 

downstream connections.

The remote preamplifier (PRE868) uses a transformer (p/n 705-603) which connected to the 

“XDCR”

 BNC 

connector on the preamplifier (see 

Figure 9 on page 23

).

For an XGF868i system configured with either a local or remote electronics enclosure and a 

dual remote preamplifier

, 

wire the transducers and preamplifier as follows:

1.

Refer to 

Figure 9 on page 23

 and use the pair of coaxial cables with BNC to BNC connectors supplied by 

Panametrics (or equivalent cables) to connect both 

CH1

 transducers to the dual preamplifier, using the 

connections on the transformer.

2.

If an optional lightning protector is installed, connect it between the preamplifier and the electronics enclosure. 

Locate the device near the electronics enclosure and install it according to the supplied wiring documentation 

for the device.

3.

See 

Figure 7 on page 21

 for the location (

J3

) of the connections for the Channel 1 transducers in the electronics 

enclosure. Using the supplied coaxial cables with BNC to flying lead connectors (or equivalent cables), route the 

cables through one of the conduit holes in the electronics enclosure and connect the preamplifier to terminal 

block 

J3

. Secure the cables with the cable clamp.

Note:

The 

RED

 cable leads are the SIG(+) leads and the 

BLACK

 cable leads are the RTN(-) leads.

WARNING!

Before connecting the transducers, take them to a safe area and discharge any 

static buildup by shorting the center conductor of the transducer cables to the 

metal shield on the cable connector.

CAUTION!

As part of maintaining the FM/CSA environmental rating (TYPE 4) on the remote 

preamplifier, thread sealant is required on all conduit entries.
