ProTekTor+IP Remote Site Monitor


The ProTekTor+IP remote monitor offers highly flexible low cost monitoring for those situations when a larger monitor is just too much. The customizable nature of the monitor allows the user to tailor the monitor to the situation at hand rather than forcing a fit with a larger more expensive monitor.

While the ProTekTor+IP is available in several versions, they all share flexibility, small size, and ease of configuration to specific uses.

The ProTekTor+IP is designed to be highly flexible and customizable. The basic features are as follows:

Features Overview:

The ProTekTor+IP monitors eight inputs, each input configurable to function in either an analog or digital mode. Analog configured inputs can monitor either positive or negative voltage inputs. Digital configured inputs can monitor bi-state inputs adhering to TLL, EIA, or non-standard logic levels, thereby ensuring virtually any equipment may be monitored without complicated external interface construction. Four relay outputs are supported. The ProTekTor+IP may be accessed locally via a DB-9 serial port or remotely via an integrated 14400 BPS modem. Support for RF modem, RS-485 or TCP/IP IP networking is available upon special request. The operating system and user configuration are stored in flash memory, which may be remotely upgraded. The real-time clock and event history are maintained in a separate NVRAM module.


The ProTekTor+IP measures approximately 8.5″ x 5.5″ x 1.25″. The ProTekTor+ site interface connection is a RJ-21 with Telco color-code pairs used for each functional pair. Future expansion or interface to specialized external equipment is supported by processor interface lines optionally accessible from the outside world. Surface mount technology is used to reduce the monitor size. A real-time clock supports time-stamped event logging and scheduling. Non-volatile memory is maintained independently of the 12 VDC input to insure against the loss of programming and history.


Communications in the standard implementation uses an internal Rockwell Socket Modem operating over any POTS line. The modem will be the primary communications pathway for outbound alphanumeric alert and status calls to any modem equipped device, including TAPP compliant paging terminals, and for all remote access by technical staff. RS-485 and TCP/IP networking are available upon request.

The serial port is used for local access and control, but also supports pass-through operation, which allows the technician to access any external ASCII device while connected to the ProTekTor+ by modem.

Power supply:

The ProTekTor+IP is powered by an external 12 VDC power source. An external wall transformer supply is available if the ProTekTor+IP is to be powered by 115 VAC mains. Users desiring operation with failed AC mains must externally provide a UPS. The low current requirements of the ProTekTor+ makes the unit attractive for solar powered or other power-constrained sites.

I/O Configuration:

The ProTekTor+IP supports monitoring of DC voltages and discrete digital logic states. Interrogation and control of external ASCII devices using the RS-232 standard is accomplished using the serial pass-through facility. All input channels tolerate returns at a differential of up to 50VDC. Alternative input characteristics may be easily achieved either during production or in the field by replacing internal configuration plugs.

Analog mode:

Standard analog configured inputs support 5VDC and 50VDC full-scale with a resolution of 0.1VDC or better. Any input may independently support negative voltages with the appropriate configuration plug.

Digital mode:

Inputs designated as digital may respond to expanded voltage ranges, as well as standard TTL or EIA levels. Traditional contact closure monitoring is also supported.


The monitor supports up to four DPDT relays, whose contacts are available at the interface connection. These relays respond to remote command or to an active input when so programmed. Control by the activity test timers is also supported. Two relays support switching of balanced signal paths.

Firmware Features:

Alarm Structure:

Alarms types of Major, Major w/ return to normal notification (RTN), Minor, and Qualifier are supported by the ProTekTor+IP. The alert sent as the result of a Major or RTN alarm event will include a time and date stamp, the user-programmed site name and ID number, the input number in alarm and its user programmed description, as well as the level or state that precipitated the alert call. Minor alarms are logged but do not generate alert calls.


The Scheduler can count to a maximum duration of approximately 71 weeks. Duration may be specified in units of seconds, minutes, hours, days, or weeks with a range of 0-99 units. The Scheduler can close a relay automatically, maintain closure for a specified period, and subsequently automatically reset. The ProTekTor+IP also has the ability to time activity or inactivity and attempt to force activity with a relay activation or by dialing a telephone number. Schedules may be combined for more complex scheduling needs.

User Interface:

The user interface will work with any communications application supporting VT-100 or ANSI terminal emulation. The adherence to a text only interface means that virtually any system can interact with the ProTekTor+IP.

Configuration and Programming:

The user will program the ProTekTor+ via the local RS-232 port or remotely by modem.

The ProTekTor+IP functions with any communications program supporting ANSI/VT100 terminal types, as well as PageTek’s SiteManager alert management software.
