Transmission of impulses via radio

REI2 can be used in combination with the LinkGate radio trans-

mission system. As well as start and ﬁnish times, it is possible to

radiotransmit 14 intermediate times, each differently identiﬁed, or

to acquire up to 16 passing speeds from as many timing zones.

Memory capacity

REI2 can permanently store about 100,000 events (naturally

memory is maintained also when the device is switched off).

Transfer from PC to REI2 of athletes’ names and the start list

In addition to normal transmission of stored data from the stop-

watch to PC, it is also possible to transfer athletes’ names and

the start lists from PC to REI2. The competitors’ names can then

appear on the Microgate graphic alphanumeric displayboards,

as well as on the stopwatch printout, thus avoiding the use of the

computer on the competition ﬁeld.

‘Multirace’ management

A number of timing sessions (up to a maximum of 8) can be

stored and called up as required, also with different function modes

(for example, single starts, group starts and parallel slalom).

Real-time rankings

When the competitor ﬁnishes, his/her provisional position in the

rankings is immediately shown on the display and displayboards.

Software updating

By connecting directly to Microgate’s Internet site, the user can in-

stall new programs or update those already installed in the device.

Time base

The time base used on REI2 is temperature-compensated and

guarantees a high level of accuracy: ±ppm equal to about ±0.08

s/day throughout the temperature range (-20°C to + 70°C). The

time base continues to function accurately even when the device

is switched off (until the batteries have run down completely),

maintaining synchronization of date and time.

Autonomy and battery recharge

REI2 is ﬁtted with high-capacity Ni-MH batteries that guarantee

about 20 hours of continuous use. Recharging is entirely man-

aged in a ‘smart’ way (discharging + recharging) to guarantee

maximum reliability. Continuous current power supply is also

possible, with an input of 10 to 30V.

Communication to PC

The stopwatch has 2 completely independent high-velocity bi-

directional lines (which can be set at 1200 to 115200 bit/s).

The two lines are dedicated to communication with the Personal

Computer (race software management, television graphics, etc.)

Displayboard management

The displayboards are commanded through a dedicated serial line.

Interfacing with displayboards of other constructors is also possi-

ble, but naturally the various display options can be exploited better

with the Microgate MicroTab and MicroGraph displayboards.

PRACTICAL AND PRECISE

REI2 NET

The way REI2 is structured offers the possibility of connecting

together up to 8 machines for distributed timing management.

The special features of REI2 Net management are as follows:

• Synchronization takes place on only one machine and from

that moment on the networked REI2s are kept constantly syn-

chronized with each other, as they can be integrated on a sin-

gle time base

• The various timing impulses can be received by all the net-

worked machines. Consequently the number of inputs and

outputs are multiplied by the number of networked machines.

The extra machines are not only auxiliary keyboards!

• The whole database of times is duplicated on every machine.

Every REI2 is a backup machine for the others.

• Addition of a REI2 to a pre-existing REI2 NET network involves

automatic synchronization of both the time base and the data-

base with the machines that are taking times.

• The possibility of assigning to a REI2 the management of a

single timing impulse (for example, an intermediate time)

without the risk of interfering with the management of starts

and ﬁnishes.

• Connection between REI2s is made with a very simple six-pole

cable.

Use of GSM

Possibility of setting a GSM connection between two or more REI2

stopwatches for the transmission of timing impulses and infor-

mation also over long distances.

Operating temperature

Functioning of the device is guaranteed for temperatures ranging

from -20°C to + 70°C.
