card consists of four baud rate generators, four RS-232-C driver/receiver pairs, and the
jumpers and logic needed to configure the UARTs.
The address select switches and logic on the card always address the UARTs using two pairs
of addresses: 0 and 1, and 2 and 3 through 15 and 16. The pairs do not need to be consecutive.
Other switches on the board determine the baud rate for each individual port and whether the
port is configured to talk to a terminal (DTE equipment) or a modem (DCE equipment).
Instructions for setting the jumpers are given later in this section.

Connector pin assignments
Connector J1 is connected to port one, and uses the RS-232-C standard DB-25-pinout.
Connector J2 is connected to ports two, three, and four, and is a non-standard pinout that
requires an adapter cable. An adapter cable (NT8D96) splits the J2 signals out to three
standard RS-232-C connectors. Port 2 is connected to connector A, Port 3 is connected to
connector B, and Port 4 is connected to connector C.
Table 281: Connector J1 pin assignments
on page 681 shows the pinouts for connector J1,
Table 282: Connector J2 pin assignments
on page 681 shows the pinouts for connector
J2.
