This connector provides the interface for connection a RS232 device. Most PC RS232 ports or other RS232 adapters are configured for DTE. The S1-A-7001 pin connection allows use of a straight-through DE-9P to DE-9S cable. The S1-A-7001 can also be connected directly to a mating RS232 port with the integral thumb-screws. -
