Version 1.0
2.4.1.6 SDLC Port, SP-3
It is located on front panel as a DB-15 female connector with latching blocks and it is labeled as
“PORT 1 SP3” and it is also available throw the DB-25 female connector labeled as “C12S SP5/SP3”.
This port uses an SDLC communication protocol and four (Tx, Rx, TxClk and RxClk) EIA-485 differential
serial communications interfaces with a default speed of 153.6 Kbps in order to meet NEMA TS2-1998
specification.
The port has a software selectable speed of 19.2Kbps, 38.4Kbps, 57.6Kbps, 76.8Kbps, 115.2Kbps,
153.6Kbps and 614.4Kbps.
This port has a dedicated pin to disable all port communication when desirable; this is accomplished by
mating a connector to this port, in which pin 8 and pin 10 are connected (0VDC = Disabled).
This port is primarily dedicated to synchronous communications in
a TS2 NEMA cabinet (BIU’s, MMU).
This port is connected to cabinet’s serial bus NEMA cabinet. The connection to the cabinet is thru a
SDLC communications cable connected to the SDLC port at one end and to the termination board on the
other end. Ensure a reliable connection by properly latching the spring latches onto the connector
’s
latching blocks.
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 female 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.
2.4.1.8 SP-5 Port
SP-5 Port is a general purpose port; it is located on front panel on a DB-25 female connector with
jackscrews and it is marked as
“C12S SP5/SP3”.
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.
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 female 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.
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
