SCDCT2565 REV B 8/10/99 Plainview NY (516) 694-6700

MSGERR

Output signal which indicates an error occurred during the current message

sequence.

TXDATA A

Bipolar serial data output to positive input of bus transceiver.

RXDATA A

Bipolar serial input from negative output of bus transceiver.

RTADP

Parity bit input for RT address.

RTAD1

Bit 1 of RT address input.

RTAD3

Bit 3 of RT address input.

RESET

System reset input - resets all inputs in module.

TXDATA B

Bipolar serial data output to negative input bus transceiver.

RXDATA B

Bipolar serial data input from positive output of bus transceiver.

12MHz

12MHz TTL clock input.

GROUND

Signal ground.

BCSTART

Cycle enable input Logic "0" initiates bus controller message transfer operation.

NBGRNT

New bus grant output from RT indicates beginning of message transfer sequence.

BITEN

Built in Test enable output indicates RT is transferring BlT word on internal 16 bit bus.

Write enable output for control of subsystem memory.

BUSGRNT

Bus request input in response to DTREQ. Allows BC/RT to transfer data to

subsystem.

LOOPERR

Loop error output. Logic "0" indicates failure of loop back transmitted data.

SSBUSY

Subsystem busy input for RT status word.

ILLCMD

Illegal command input to RT, used to block RT response to an illegal command.

ADRINC

Increment output pulse. Goes LOW at the completion of each word transfer to/from

subsystem. Can increment external address counter.

CHASSIS

Frame ground electricity isolated from signal ground

WC0

LSB of current command word count field.

WC2

Bit 2 of word count field.

WC4

Bit 4 of word count field.

TXINH A

Transmitter inhibit output signal for Channel A.

LMC

Latched Mode Command. Logic "1" indicates current word command is a mode code

word, WC0-WC4.

TESTIN

Factory test point. Do not connect.

EOM

End of message output. Logic "0" occurs when BC/RT message is completed.

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.
