DIPSWITCHES AND JUMPERS
I-E96-221A
3 - 3
•
Jumper array J5 selects DTE, DCE, or loopback operating
mode for the DB-25 EWS port (P4).
•
Jumper array J6 selects DTE, DCE, or loopback operating
mode for the DB-9 connector mounted on the circuit
board.
•
Jumper J11 allows the CTT terminal to connect directly to
the module bus therefore disabling IMCPM02 module con-
trol. Jumper J11 causes the IMCPM02 module to operate
as an IMCPM01 module.
•
Jumper J12 disconnects -30 VDC from the module when
installing it in an MMU backplane with modules that
require -30 VDC. The Controlway can not be used in sys-
tems that use -30 VDC.
NOTE: Since factory settings do not reflect default settings, it is
imperative that all dipswitch settings are checked before you put the
module into operation.
Dipswitch SW2 - Module Options and Diagnostics
Dipswitch SW2 sets a variety of module options. Refer to Table
for option setting information. Refer to
for diag-
nostic dipswitch setting information. This dipswitch provides
the following functions in normal operation mode:
•
One pole to select the display of the EWS port or CTT inter-
face activity on the LEDs.
