MODULE INSTALLATION

Dans le document line interface (Page 21-31)

The DLVll-E or DLVll-F module can be installed in any slots in the LSI-ll backplane, except the first four slots (the LSI-ll processor always occupies the first slots). Do not leave any unused option locations between the processor and the DLVll-E or DLV11-F. An open slot would break the inter-rupt acknowledge daisy chain. The priority of the module is determined by its proximity to the proces-sor on the bus (refer to Figure 3-5). The closer the slot is to the procesproces-sor module, the higher the interface module's priority.

Determine the appropriate slot for the module. For example, if a DLVll-E is interfacing commu-nications lines from a host computer, it would normally be placed in the slot closest to the processor module, followed by the module interfacing the console terminal. Refer to Microcomputer Handbook (DIGITAL part number EB 06583 76) for system considerations.

Table 3-1 Jumper Definitions NOTE

This table pertains to both the DLVll-E and the DLVll-F, except as noted. Jumpers are inserted to enable the function they control except for those jumpers that indicate negation (such as "-B" and

"B"). Negated jumpers are removed to enable the functions they control.

Function

These jumpers correspond to bits 3-12 of the address word. When inserted, they will cause the bus interface to check for a True condition on the corresponding address bit.

Used to generate the vector during an interrupt transaction. Each inserted jumper will assert the corresponding vector address bit on the LSI-II bus.

Receiver and transmitter baud rate select jumpers, during common speed operation.

Receiver only baud rate select jumpers during split speed operation (see Table 3-2).

Transmitter baud rate select jumpers during split speed operation.

Both receiver and transmitter baud rate if maintenance mode is entered during split speed operation (see Tale 3-2).

Jumper is inserted to enable Break generation.

Jumper is inserted for operation with parity.

Removed for even parity; inserted for odd parity. Receiver checks for appropriate parity and transmitter inserts appropriate parity.

These jumpers select the desired number of data bits (see Table 3-3).

Jumper is inserted to enable the programmable baud rate capability.

These jumpers are inserted for common speed operation. (Note that S and Sl must be removed when C and Cl are inserted.)

Inserted for split speed operation. (Note that C and Cl must be re-moved when Sand SI are inserted.)

This jumper is inserted to assert BHAL T L when a framing error is received, except when the Maintenance bit is set. This places the LSI-II in the halt mode.

Jumper

Table 3-1 Jumper Definitions (Cont) Function

Jumper B is inserted to negate BDCOK H when a BREAK signal or framing error is received, except when the Maintenance bit is set. This causes the LSI-II to reload the bootstrap. (Jumper -B orB must be removed when B is inserted.)

Jumper is removed to force DATA TERMINAL READY signal on.

Jumper is removed to force REQUEST TO SEND signal on.

This jumper is inserted to enable normal transmission of the REQUEST TO SEND signal.

Inserted to enable transmission of the FORCE BUSY signal (for Bell model 103E data sets).

These three jumpers are inserted to make the 20 rnA current loop receiver active. (Jumpers IP and 2P must be removed when lA, 2A, and 3A are inserted.)

These jumpers are inserted to make the 20 rnA current loop receiver passive. (Jumpers lA, 2A, and 3A must be removed when I P and 2P are install ed. )

Inserted to make the 20 rnA current loop transmitter active. (Jumpers 3P and 4P must be removed when 4A and 5A are inserted.)

Inserted to make the 20 rnA current loop transmitter passive. (Jumpers 4A and 5A must be removed when 3P and 4P are inserted.)

Jumper is removed to enable the error flags to be read in the high byte of the Receiver Buffer.

When inserted, enables maintenance bit.
