on the back of the PMU (this cable will be re-connected later in the installation).

2.Switch the On/Off switch on the back of the PMU to the “On” position.

3.Verify that the “PWR” indicator on the front panel of the PMU stays on continuously.

4.Verify that the three other indicators on the front panel of the PMU are flashing in a repeating sequence. The “MUX” indicator should flash once every 250 milliseconds; first by itself, next with the “DATA” indicator, and then with the “ALARM” indicator.

PMU PROGRAMMING

The PMU’s operational program will use the factory default values for its operational parameters unless re- configured by the user. The user-configurable parameters may be re-configured through the use of an RS232 CRT terminal (or PC with terminal emulation software) connected to the PMU.

CAUTION

Changing parameters not covered in this manual may lead to unsatisfactory operation of the PMU option.

2.Turn the terminal on and set the communications protocol per Table 5.

Terminal Setup

The following initial steps are required to set up the terminal and access the PMU.

1.Connect the RS232 CRT terminal to the left-hand VDT Interface connector on the back of the PMU (see Figure 12). (DO NOT plug into the front of the PMU.) If the RS232 CRT terminal has a male DB-25 port, connect per Figure 13. If the terminal has a male DB-9 port, connect per Figure 14.

CAUTION

DO NOT plug the RS232 CRT terminal into the front panel of the PMU (damage to terminal may result). This connnector is for another device in another application.

Software Initialization

Before you attempt to program any PMU parameters, all parameters should be returned to the factory default values. The following procedure is used to initialize the PMU with its factory defaults:
