Figure 1: FleX Controller Models.
The FleX Controller units use an engine board based on ATC 6.24 standard and TEES 2009 ERRATA 2;
with the MPC8360 core at 400MHz, 256MB DRAM, 16MB NOR FLASH, 256MB NAND FLASH and 2MB
SRAM.
The unit has three RS-232 asynchronous serial communication ports with software selectable speed from
1.2Kbps to 115.2Kbps, these ports (SP1, SP2 and SP4) are available over DB-9 female connectors. SP1
and SP2 ports are located on the back panel and SP4 port is located on front panel, this port is used
primarily for connecting a terminal computer or as a general purpose.
T
wo SDLC ports are designated to synchronous communications to cabinet’s serial bus, they are RS-485
serial communication port with software selectable speed from 19.2Kbps to 614Kbps available over a
DB-15 female connector for a NEMA Cabinet (SDLC SP3) or over a DB-25 female connector for ATC
Cabinet (C12S, SP3/SP5) both on the back panel.
The unit also has 2 high speed USB ports to download and upload databases. These ports are connected
to a USB hub which is routed to the ATC Engine. One USB port is located on the front panel and the
second port is located on the back panel of the controller.
Five 100MBPS Ethernet ports are provided for communicating with a central, connecting to peripheral
devices, and also for operating as a remote terminal to download/upload files, updates, log files, etc. Two
of them are installed in the front panel, the other two Ethernet ports are installed in the back panel and
one is located inside of the controller, in the hostboard PCB assembly.
