Figure 5-4. Connecting DACRs to the IMS
If your RS-232 card has a DB25 male connector, complete the following steps.
Refer to Figure 5-4 for help. (If it has a DB9 male connector, complete the
steps in the previous section.)
1. Ensure that the power is OFF before starting this procedure.
2. Complete all wiring according to the wiring shown in Figure 5-3.
3. Use the junction boxes at each end of the installed cable to terminate the
field wiring between harness 733-571 and 733-572.
• The total wiring length from the RS-232 port of the CPU to the RS-232
port of the DACR must not exceed 20 feet (6 m) and must be run in
conduit.
4. Complete Steps 1 through 4 for each DACR that you are installing.
5. After connecting the DACR(s) to the IMS, turn the power ON.
6. Press ESCAPE to enter the configuration mode.
