4.2.1 Type 2070 – 1A Configuration<br />
The TYPE 2070-1A CPU shall consist <strong>of</strong> the Main <strong>Controller</strong> Board, Transition Board,<br />
Board Interface Harness, and CPU Module S<strong>of</strong>tware.<br />
4.2.2 Type 2070 – 1B Configuration<br />
The TYPE 2070-1B CPU shall be a single board module meeting the 2X WIDE board<br />
requirements. The module shall be furnished normally resident in MOTHERBOARD Slot<br />
A5. The module shall meet all the requirements listed under this section and Chapter<br />
Details 4.7 except for the following:<br />
4.2.2.1<br />
The VME s<strong>of</strong>tware and hardware bus requirements shall not apply nor do the MCB and<br />
Board Interface Harness physical requirements.<br />
4.2.2.2<br />
A Dual SCC Device (asynch / synch) and associated circuitry shall be furnished to<br />
provide two additional system serial ports. The Dual SCC1 shall be assigned to the<br />
System Serial Port SP1 meeting all requirements called out for SP1. The Dual SCC2<br />
shall be assigned as System Serial Port SP8. The SP8 and associated circuitry shall<br />
interface with the MC68360 address and data structure and serially be connected to the<br />
external world via the DB 25 Pin C13S Connector located on the module front panel. The<br />
SP8 shall meet all SP2 Port requirements including EIA 485 Drivers / receivers and<br />
synchronous bps rate <strong>of</strong> 614 Kbps. An internal LOGIC Switch shall be provided to<br />
disconnect SP8 RTS, CTS and DCD ( Pins 5, 6,7,18,19 and 20 ) lines from C13S<br />
connector.<br />
4.2.2.3<br />
The 68360 SCC1 shall be reassigned to ETHERNET (ENET) Network meeting<br />
ETHERNET 10 MBPS IEEE 802.3 (TP) 10 BASE T Standard Requirements, both<br />
hardware and s<strong>of</strong>tware. The four network lines shall be used to route ETHERNET across<br />
the MOTHERBOARD to the “A” Connectors. DC Grounding plane around the network<br />
connectors and lines shall be provided. Network Lines shall be assigned as: Network 1 =<br />
ENET TX+, Network 2 = ENET TX-, Network 3= ENET RX+, and Network 4 = ENET<br />
RX-. In addition, the conditioned ETHERNET shall be brought out on RJ 45 C14S<br />
Connector mounted on the CPU-1B Front Panel. Four LEDs labeled “TX, RX, TX<br />
Collision and TX Status” shall be mounted on the front panel signifying ETHERNET<br />
operational conditions.<br />
