Rj-45/Rj-45 Jumper Settings - Black Box Async 232 422/530 Manual

DTE as DSR or RI (JB6 and JB7)
Because this rear card is designed to function in more applications than the
Async 232↔422/530 Card, this jumper must be installed only in one position.
Place the jumper across pins 1 and 2 so that the terminal (DTE) sees DSR as
high when the rack is powered. The other positions, across pins 2 and 3, are
for Ring Indicate as defined by EIA/TIA-561. The RI function is irrelevant
(and on the Async 232↔422/530 Card is also disconnected) and can cause
improper operation if the jumper is installed incorrectly.
Position 1 & 2 = DSR
Position 2 & 3 = N/A
SGND and FRGND (JB5)
In the connected position, this jumper links RJ-45 pin 5 (Signal Ground) and
frame ground through a 100-ohm,
is disconnected from frame ground.
Position 1 & 2 = SGND (Pin 5) and FRGND Connected
Position 2 & 3 = SGND (Pin 5) and FRGND Not Connected
3.3.2 RJ-45/RJ-45 J
Figure 3-5 shows the strap locations for the IC475C rear card. These jumpers
determine grounding characteristics for the RS-232 and twisted-pair converter
lines.
