The JRS232 connector provides the Turbo PMAC2 VME with the ability to communicate serially with an RS232
port. Jumpers E17 and E18 must both connect pins 1 and 2 to use this port. This connector cannot be used for
daisy chain interconnection of multiple PMACs. The J5A RS-422 port is required for daisy chaining.
