devices for transferring data files from and to the controller; these data files can be firmware upgrades,
databases, etc.
They are labeled as “USB”.
2.4.8 SP4, Terminal PC or General Purpose port
SP4 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 two indicator leds (Tx and Rx). It is labeled as
“SP4”. 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.
2.4.9 SP1 Port
SP1 Port is a general purpose port; it is located on the back panel on a DB-9 female connector with
jackscrews and two indicator leds (Tx and Rx). It is labeled as
“SP1”. This port uses RS-232
asynchronous serial communications with software selectable speed from 1.2Kbps to 115.2Kbps, with a
default speed of 9.6Kbps.
2.4.10 SP2 Port
SP2 Port is a general purpose port; it is located on the back panel on a DB-9 female connector with
jackscrews and two indicator leds (Tx and Rx). It is labeled as
“SP2”. This port uses RS-232
asynchronous serial communications with software selectable speed from 1.2Kbps to 115.2Kbps, with a
default speed of 9.6Kbps.
2.4.11 SDLC Port, SP3
SP3 port is located on back panel as a DB-15 female connector with jackscrews and two indicator leds
(Tx and Rx). It is labeled as “SDLC SP3”, it is also available throw the DB-25 female connector labeled as
“C12S SP3/SP5”.
This port uses a 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.
The pin 10 of this port is dedicated to disable all port communication when desirable; this is accomplished
by connecting 0 VDC to this pin. The following pins has 0 VDC: 2, 4, 6 and 8.
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.
2.4.12 SP5 Port
SP5 Port is located on back panel on a DB-25 female connector with jackscrews and two indicator leds
(Tx and Rx). I
t is labeled as “C12S SP3/SP5”.
