Pin Assignments

Ashielded, 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.
