DTE vs. DCE:

Cable:

The RS-232 interface is attached to a RJ-45 to DB-9 connector with either a 4 conductor or 8 conductor “phone” cable. The cable is NOT pin compatible with standard 4 conductor phone cords. See Figure 2: Connection Cable. For a

4 conductor cable only pins 3,4,5,6 on the RJ-45 connector will be used. As of software revision

8.04only pins 3,4,5,6 are supported eliminating the necessity for 8 conductor connections.

Protocol:

The 2-way RS-232 standard for the Destiny control panel is an open standard and is available by calling Technical Support at 800-272-7937.

The RS-232 interface can operate in either Date Terminal Equipment (DTE) or Data Communication Equipment (DCE) mode. A jumper (J3) is located to the right of the RJ-45 on the interface board. Attach the supplied jumper across the center and bottom pin for DCE operation or the top two pins for DTE. Most applications will require DCE including connection to a PC and a printer.

Programming:

The following programming options are provided:

001- Enable the RS-232 adapter

002- Enable printer compatibility

004- Use English Line text (for printers only)

008- Enable 2-Way RS-232 communication (for PC connections)

064- Enable Remote System Mode

Place the system into program mode (default: 9,1,7,3), enter location 0,1,5,5 and then enter the sum of options to be enabled. For example, to enable 2-way communication, enter 0,0,9 (001 + 008). For printing, enter 0,0,7 (001 + 002 + 004).

Printer Reports:

When enabled (as described in Programming, above), any event programmed to appear in the Event Memory Log will be printed when an event occurs. All items in the system that can be sent to a central station will be printed as the event occurs. The “Report to Central Station” programming option does not affect the printer report.

Note: the RS-232 does not buffer events, if a printer is off-line the event will not be printed.

Format:

The following is an example of the printer output when connected to the RS-232 port.
