    Configuration Protocol (DHCP). Manual network configuration is via the RS-232 serial I/O port. Free FLASH Upgrades Firmware is stored in non-volatile FLASH memory, so the PDC3301 can be easily upgraded in the field using the local RS-232 port. We make all firmware upgrades for our products available to our customers free of charge.

    AC or DC input voltages. (Installation of a second power supply is an option for the PDC3301.) The presence of proper voltage at the output of each of the two inter- nal DC-DC converters is detected and monitored by the alarm logic and CPU. The outputs of these two power supplies are diode “OR’d”...

    �� RS-232 Connector This DB-9M connector provides the RS-232 serial I/O interface to the PDC3301. This allows the user to initialize, monitor and control the PDC3301. See Chapter 3 - RS-232 Serial I/O Port Signal Definitions for detailed information. 10/100Base-T Jack This optional RJ-45 connector mates with the ethernet twisted pair cable from the network.

  • Page 17: Installing The Pdc3301

    Power cord is used as a disconnection device. To de-energize equipment, disconnect the power cord. If your PDC3301 has dual power supplies, then multiple power cords may be installed. To de-energize this equipment, disconnect all power cords from the device.

  • Page 18: Connect Serial I/O To Host Computer

    If the source(s) of your reference signal(s) has (have) compatible TTL alarm output(s) that you would like to use to force signal input switching on your PDC3301, connect these using coaxial cables to the A and/or B disable input(s) on the PDC3301. The factory default for the PDC3301 disablemode setting is to ignore these inputs.

  • Page 19: Chapter Three - Control And Status Commands

    Chapter Control and Status Commands This chapter describes the PDC3301 control and status commands. The PDC3301 supports com- mands for performing initialization/setup and for monitoring the performance and status of the unit. The serial I/O port physical and electrical characteristics are defined as well.
