1 BACKGROUND


We will temporarily deploy a STS-2.5 seismometer at KTK1. A new junction box must be made, where the 4-pair STP cable running between vault and recording cabin will be terminated; on the opposite side an interface cable connects to the STS-2.5 Host Box.

The side that faces the digitizing equipment is furnished with a 24-way connector. A suitable cable connector is recommended in the STS-2.5 User manual V1.1 p.9: CA3106PG24-28P-A176.

There are many different types of these MIL-type connectors, and many manufacturers.
