NON-VOLATILE MEMORY (E2PROM) DESCRIPTION The Gemini 5200 is a multifunction dual rate indicator which can fulfill almost any rate indication application. The unit can operate as two independent rate indicators, with scaling, decimal point placement, and update times separately programmable for each channel. The Gemini 5200 also has three other unit personalities. These personalities feature a third display Channel C, which can indicate the ratio, difference or draw between the A and B rate channels. The programming of the rate channels and the calculated display is a very straightforward task. Setting up Channel C only requires programming the desired amount of resolution (for ratio and draw) and the appropriate decimal point location. The Gemini 5200 simply takes the two rate values and mathematically calculates display “C” accordingly. The rate indicators use a time interval method (1/tau) to calculate the rate value. This method enables high resolution at all input rates. The unit counts input pulses and after a programmable minimum update time has occurred, it waits until the next count edge occurs, then takes the elapsed time and number of edges and calculates the rate value. At slower rates, averaging can be accomplished by programming the “Rate Minimum Update Time” (0.5 sec. to 16 sec.) for the desired response. The minimum input frequency is 0.03 counts/sec. or one pulse every 32 sec. Extensive scaling capabilities allow practically any desired reading at very slow input rates. The 20 mA Current Loop Communications Option provides the capability of two-way serial communications between the Gemini and other equipment such as a printer, programmable controller, or host computer. The baud rate can be set to 300, 600, 1200, or 2400 baud. The format for transmitted and received data is 1 start bit, 7 data bits, 1 parity bit (odd), and a stop bit. When utilizing an external power supply (30 VDC max.), up to sixteen units can be installed in the loop, each with an individual address. When utilizing the Gemini’s 20 mA current source, up to seven units can be installed in a loop. The Rate values, Presets, and Scale Factors can all be interrogated, while the Presets and Scale Factors can also be changed by sending the proper command codes and numerical data. Various “Print Options” can be selected to automatically interrogate the Rate values, Presets, or Scale Factors by activating the “Print Request” terminal when a printer is being used. The construction of the Gemini 5200 features a metal die-cast bezel, offering maximum durability with a high quality appearance. The sealed front panel meets NEMA 4/IP65 specifications for wash-down and/or dust when properly installed. Electrical connections are made via plug-in terminal strips. Clamptype pressure plate terminals accept stripped #14 AWG wire without lugs. SPECIFICATIONS 1. DISPLAY: 6-digit 0.56" (14.2 mm) High LED display. 2.

3 PROGRAMMING The Gemini 5200 input circuit set-up is programmed using DIP switches on the rear of the unit. All other functions are programmed through the front panel pushbuttons. To program or interrogate a function, the user first enters a two-digit function code. The unit will then display that function code along with a single-digit mode identifier. EXAMPLE: The function code representing “Output 1 Termination Modes” is 52. The mode identifiers for this function are: 3. Terminate at Manual Reset 4. Terminate at Manual Reset End 5. Terminate after Timed Output 1 6. Boundary To interrogate...
