CONFIGURATION
Each RTU will need to be configured prior to its use unless the factory default initialization
values are satisfactory for the application.
To configure an RTU, you will need:
1. A “dumb terminal” or a PC running in the dumb terminal mode. Software programs
such as CrossTalk, Kermit, ZCU, Procomm, and others will provide terminal
emulation on a PC.
2. A cable with a male 9-pin, D-style connector on one end to interface with the RTU
and a connector on the other end to interface with the serial port of your PC or dumb
terminal.
Note
The pins on the RTU are different from those of other serial ports found on printers
and modems. You will need to use the cable provided with the Model 1700
Controller, make up your own cable, or purchase an additional cable from Zetron
for programming the RTUs.
Accessing the RTU Program Mode
1. Connect the serial cable between J2, the 9-pin “D” style connector on the RTU, and the
serial port of the PC or dumb terminal.
2. Connect a 12-volt power supply with power off to the RTU pin 1 of P3 and ground to pin
2 of P3.
3. Make sure your dumb terminal or PC is set at 4800 baud, 8 bit, no parity, 1 stop bit.
4. Turn the 12-volt power supply on. You should see the RTU model number and the
software version displayed on the CRT.
5. Press the space bar three times to enter the Main Menu.
