REMOTE MINIBRIDGE
Appendix: WAN Pinouts
The DB25 WAN connector that most of the Remote
MiniBridge models have is pinned out differently on
different models of the RMB, depending on which WAN
interface the model uses. RS-232 models use the normal
TIA RS-232-C pinout shown in the “RS-232” column of
Table A-1 on pages 34 and 35. RS-530 models use the
normal TIA RS-530 pinout shown in the “RS-530”
column. The RS-449 (V.36) and X.21 models also use
this pinout for the DB25 connector, but they include
adapter cables that patch the leads/signals shown in the
“RS-530” column to the matching leads/signals on DB37
and DB15 connectors, respectively; these are the pins
listed in the same row in the “RS-449” and “X.21”
columns. The V.35 models use the proprietary pinout
shown in the “V.35 (DB25)” column, but they include
an adapter cable that patches this to an M/34
connector, pinned out for standard V.35 as shown
in the “V.35 (M/34)” column.
NOTE: The “signals” named BAUD2, BAUD1,
BAUD0, and ACCM in Table A-1—on DB25 Pins 6, 8,
17, and 22 respectively—are leads you can use in async
mode to control the data rate and the octet-stuffing
