30
MSGERR
Output signal which indicates an error occurred during the current message
sequence.
31
TXDATA A
Bipolar serial data output to positive input of bus transceiver.
32
RXDATA A
Bipolar serial input from negative output of bus transceiver.
33
RTADP
Parity bit input for RT address.
34
RTAD1
Bit 1 of RT address input.
35
RTAD3
Bit 3 of RT address input.
36
RESET
System reset input - resets all inputs in module.
37
TXDATA B
Bipolar serial data output to negative input bus transceiver.
38
RXDATA B
Bipolar serial data input from positive output of bus transceiver.
39
12MHz
12MHz TTL clock input.
40
GROUND
Signal ground.
41
BCSTART
Cycle enable input Logic "0" initiates bus controller message transfer operation.
42
NBGRNT
New bus grant output from RT indicates beginning of message transfer sequence.
43
BITEN
Built in Test enable output indicates RT is transferring BlT word on internal 16 bit bus.
44
WR
Write enable output for control of subsystem memory.
45
BUSGRNT
Bus request input in response to DTREQ. Allows BC/RT to transfer data to
subsystem.
46
LOOPERR
Loop error output. Logic "0" indicates failure of loop back transmitted data.
47
SSBUSY
Subsystem busy input for RT status word.
48
ILLCMD
Illegal command input to RT, used to block RT response to an illegal command.
49
ADRINC
Increment output pulse. Goes LOW at the completion of each word transfer to/from
subsystem. Can increment external address counter.
50
CHASSIS
Frame ground electricity isolated from signal ground
51
WC0
LSB of current command word count field.
52
WC2
Bit 2 of word count field.
53
WC4
Bit 4 of word count field.
54
TXINH A
Transmitter inhibit output signal for Channel A.
55
LMC
Latched Mode Command. Logic "1" indicates current word command is a mode code
word, WC0-WC4.
56
TESTIN
Factory test point. Do not connect.
57
EOM
End of message output. Logic "0" occurs when BC/RT message is completed.
58
BUFENA
Buffer enable input, may be driven LOW by STATEN or BITEN if subsystem must read
bit or Status words. Enables internal 16 bit bus onto subsystem bus.
