TQK50 Jumper and Switch Settings ======================================================================== The TQK50 (M7546) is a Q-bus controller for a TK50 tape (CompacTape (tm)) drive. It has two DIP switch sets (hardware revision level and unit number) and one jumper set (CSR address). ======================================================================== The hardware revision level DIP switch is set to match the module revision level, which is stamped on the back of the module. The eight switches represent a binary value: open = 0, closed = 1. Revision Switch Level 8 7 6 5 4 3 2 1 ---------------------------------- 0 0 0 0 0 0 0 0 0 1 (A) 0 0 0 0 0 0 0 1 2 (B) 0 0 0 0 0 0 1 0 3 (C) 0 0 0 0 0 0 1 1 ... ... The unit number DIP switch is similar: Unit Switch Number 8 7 6 5 4 3 2 1 ---------------------------------- 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 1 2 0 0 0 0 0 0 1 0 3 0 0 0 0 0 0 1 1 ... ... The VMS operating system does not use these data. ------------------------------------------------------------------------ The jumpers set the CSR address (bits 12-2). Jumper removed = 0, installed = 1. /----------- Jumpers -----------\ CSR bit: 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Binary: 1 1 1 1 1 1 1 1 1 j j j j j j j j j j j 0 0 `-----' `-----' `-----' `-----' `-----' `-----' `-----' Octal: 1 7 7 6,7 0-7 0-7 0-7 0,4 Example, 17774500 (default): /----------- Jumpers -----------\ CSR bit: 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Binary: 1 1 1 1 1 1 1 1 1 1 1 0 0 1 0 1 0 0 0 0 0 0 `-----' `-----' `-----' `-----' `-----' `-----' `-----' Octal: 1 7 7 7 4 5 0 0 ======================================================================== Jumper and Switch Locations: \ / +===========================-----------------------------------+ | \ J1 / | | | (Drive cable connector) | | | +-------------------------+ | | | --------------------------------, | | / | | '----------------------------------- | CSR | | | |A12 o-o | |A11 o-o | |A10 o o Hardware | |A09 o o Revision | |A08 o-o Level | |A07 o o +---+ | |A06 o-o | 1 | | |A05 o o | 2 | Unit | |A04 o o | 3 | Number | |A03 o o | 4 | +---+ | |A02 o o | 5 | | 1 | | | | 6 | | 2 | | | | 7 | | 3 | | | | 8 | | 4 | | | +---+ | 5 | | | | 6 | | | | 7 | | | | 8 | | | +---+ | | | | +--------+ | | | | | | | | | +-------------------------+ +-------------------------+ ======================================================================== In SYSGEN CONFIGURE for a TQK50, specify device "TU81".
