JUMPERS J11 AND J12
Jumpers J11 and J12 are storage posts for extra jumpers.
JUMPER J13
Jumper J13 with pins one and two jumpered connects RS-485
cable shielding (P7, pin one) to chassis ground.
JUMPERS J14 THROUGH J17
Jumpers J14 through J17 allow proper routing of the signals
on the termination module circuit board. These alternate sig-
nals are not related to data communications and are reserved
for future use. For proper RS-232-C and RS-485 operation,
these must be left in the pins one and two jumpered configura-
tion.
