DIPSWITCHES AND JUMPERS
I-E96-221A
3 - 7
JUMPERS J1 THROUGH J3
Jumpers J1, J2 and J3 enable the handshake functions for
the serial (EWS) port and must be set to match the equipment
used. The IMCPM02 module is shipped with these jumpers
installed for +12 VDC (logic 0). Removing the jumpers allows
the signals to float and may prevent the IMCPM02 module
from communicating with the EWS station.
JUMPER J4
Jumper J4 connects the shield of the RS-232-C connector
cable to chassis ground through the IMCPM02 module. The
cable shield should be grounded at either end, but never both
ends. If the cable shield is grounded at the computer end,
short pins 2 and 3 of jumper J4. This opens the ground con-
nection between the cable shield and the IMCPM02 module.
JUMPER ARRAYS J5 AND J6
Set jumper arrays J5 and J6 to match the type of equipment
(DTE or DCE mode) communicating with the IMCPM02 mod-
ule. Jumper array J5 selects DTE, DCE, or loopback operating
mode for the serial port (P4). Jumper array J6 selects DTE,
DCE or loopback operating mode for the unused utility port
mounted on the circuit board. Either port can be DCE or DTE
mode.
For connection to DCE equipment (modems) set up the
IMCPM02 module as DTE mode. For connection to DTE equip-
ment (computers such as the EWS) set up the IMCPM02 mod-
ule as DCE mode.
For DCE type equipment (modems), install CPM jumpers J5
and J6 as shown in Figure
. For DTE type equipment (com-
puters such as the EWS), install the jumpers as shown in Fig-
ure
. Confirm the equipment pinout to verify the RS-232-C
standard before setting jumpers. Figure
shows the settings
for jumper arrays J5 and J6 during diagnostics (loopback
mode).
JUMPERS J11 AND J12
Jumper J11 is normally set shorting pin 2 to pin 3. This allows
the CTT02 terminal to talk on the Controlway under IMCPM02
module control. If all the modules on the controlway are oper-
ating in module bus mode, you can connect the CTT02 termi-
nal directly to the module bus. Do this by shorting pin 1 to pin
2; when the CTT terminal is connected directly to the module
bus, the EWS port will not communicate on the module bus.
