other end. Ensure a reliable connection by properly latching the spring latches onto the connector’s
latching blocks.
For port’s pin assignments see appendix D.
2.4.1.7 Port 2, SP-4, Terminal PC or General Purpose port
Port 2 is a general purpose port but it is primarily used for connecting a terminal and to perform data
transfer between the controller and an external computer.
It is located on front panel on a DB-9 male connector with jackscrews and it is labeled as Port 2. RTS,
CTS and DCD lines are not available on this port.
This port uses RS-232 asynchronous serial communications with a software selectable speed from
1.2Kbps to 115.2Kbps, with a default speed of 115.2Kbps.
For port’s pin assignments see appendix D.
2.4.1.8 SP-5 Port
SP-5 Port is a general purpose port; it is located on front panel on a DB-9 male connector with jackscrews
and it is marked as SP-5.
This port uses RS-232 asynchronous serial communications with software selectable speed from 1.2Kbps
to 115.2Kbps, with a default speed of 38.4Kbps.
For port’s pin assignments see appendix D.
2.4.1.9 SP-8 Port
SP-8 Port is a general purpose port; it is located on front panel on a DB-9 male connector with jackscrews
and it is marked as SP-8. This port uses RS-232 synchronous serial communications with software
selectable speed from 19.2Kbps to 614.4Kbps, with a default speed of 153.6Kbps.
For port’s pin assignments see appendix D.
2.4.1.10 Communications Modem Slot
SP-1 and SP-2 are general purpose ports and they are available on the communications slot at DIN96
connector.
The ports’ differential communications signals are used depending on the board plugged into the
communications slot (2070-7A, 2070-7B, 2070-6A, 2070-6B, etc); if the board is an asynchronous
communications board (such 2070-7A/6A/6B) the speed is software selectable from 1.2kBbps to
115.5Kbps, if the board is a synchronous communications board (2070-7B) the speed is software
selectable from 19.2Kbps to 614.4Kbps.
For port’s pin assignments see appendix D.
2.4.1.11 A2 Connector
This circular connector provides the AC connection (Line, neutral and chassis ground) and also the fault
monitor (FM) output. This connector is intended to be used when the controller is installed into NEMA
TS2 Type 1 cabinets.
