System 310
I/O CONNEC ORS
The back panel accommodates up to 24 connectors of various sizes.
Each connector fits into a knockout designed to fit common male or
female connectors. The various sizes of connector knockouts are
listed below:
C nnect r Type Number Available
15-pin D sub-miniature c nnect rs 2
25-pin D sub-miniature c nnect rs 10
50-pin delta ribb n c nnect rs 2
75- hm BNC c nnect rs 5
37-pin D sub-miniature c nnect rs 4
36-pin delta ribb n c nnect r 1
CIRCUI BOARDS
The cardcage and backplane assembly governs the number, size, and
type of boards that fit in the chassis. This assembly provides slots
for up to seven MULTIBUS-sized boards (6.75" x 12"). Two of the
seven card slots are spaced to accept cards that host MULTIMODULE
boards and thus require more height clearance.
All System 310 cards communicate with each other through the
backplane using an IEEE 796 standard MULTIBUS interface. In
addition to this protocol, 286-based systems also support the iLBX
bus interface.
NOTE
The System 310 exceeds the MULTIBUS
peak-to-peak ripple tolerance specification.
See Appendix A for the new numbers.
ELEC RICAL COMPA IBILI Y
When choosing features, you need to know the amount of DC that
the chassis supplies to the circuit cards and peripherals. Table 3-1
describes the operating parameters of the standard power supply. It
lists the maximum number of amps available at each voltage level.
Table 3-1. 220-Watt Power Supply Specifications
Maximum DC Available
30.00 amps at +5 v lts
4.70 amps at +12 v lts
4.70 amps at -12 v lts
