Pin Assignments

A shielded, hydra-style breakout cable providing four 37-pin, D-shell (DB-37) DTE

connectors is available for the SunHSI/U adapter. Since there are not enough wires

to create the signal ground (pin 19) connections, use the shield ground (pin 1) of the

DB-37 connector for this signal. The pin assignments for the cabling and connectors

are shown in

TABLE A-1.
