Cable Construction Information

If you plan to construct your own VHSI cables, be sure to observe the

guidelines given below.

Wire Gauge, Grounding, and Pairing

• Use 28 AWG 7-strand wire with 0.020–0.028" insulation.

• The chassis must be grounded both by a drain wire and by the

braid; both must be connected to the connector case and shell at

each end of the cable. The braid must be connected through its

full circumference.

• Wires identified under the heading “Twisted Pairs” must be

paired. If you do not install twisted pairs correctly, the cable will

not work.

Type of Connectors

The VHSI port accepts a high density 36-pin male cable connector.

The types of connector used on the interface-specific end of the cable

are as follows:
