NOTE
The header pins are thin and you might damage them if you handle the link care-
lessly.
Align the pins of the replacement header with the receptacles in the socket. The socket has a corner
cut off to ensure that the orientation is correct as shown in
Figure 4-4 . Press the link header carefully
into position until it seats properly in the socket. Check that none of the pins have become bent or
damaged and that all are inserted fully into the socket.
Each of the headers has a different Teledyne TSS part number and establishes a different
communications protocol. You may order a complete set of SEP headers from Teledyne TSS if you
need to change the communication method.
Table 4-8 lists the part numbers for the SEP headers.
Once you have set both links, follow the instructions in section 9.2.2.1 "Sub-sea Electronics Pod" on
page 9-6 to re-assemble the SEP.
