T800 Paging SystemsT800 Paging Systems A beginners guide to Tait’s paging offerings Tait Radio Systems Division Tait Electronics Ltd August 2002 T800 Paging Systems Page 2 of 2 1 Types of paging modulators/Transmitters Tait currently manufactures the following paging products: T800-30-0000 Differential Frequency Shift Keying, paging board suitable for use with 512 or 1200 baud Pocsag or speech T800-30-0002 As above but with external frequency reference. T800-32-0000 Low Speed Paging Modulator, suitable for use with 512, 1200 or 2400 baud Pocsag or 1600 baud FLEX. T800-32-0002 As above but with external frequency reference. T837-20-1020 Low Speed Paging Exciter, purpose built VHF exciter for use with 512, 1200 or 2400 baud Pocsag or 1600 baud FLEX. This is essentially a VHF exciter with the T800-32- 0000 paging modulator built into it. It does not have voice capability. T837-20-1021 As above but with external frequency reference. In addition to the above, you can order directly from the factory a T8xx-xx-1010 or T8xx-xx-1012 exciter or transmitter. These come with the T800-32-000x kit already fitted, and all required modifications done. These are suitable for UHF or 800/900 MHz paging requirements where we have not developed the Paging only exciter. Tait Electronics Ltd August 2002 T800 Paging Systems Page 3 of 3 2 High Stability Oscillator For wide area paging solutions, you will require some form of external frequency reference. The T801-20-0000 is a 10MHz OCXO reference with .001ppm stability and manually adjustable offsets up to 5ppm suitable for use with VHF wide area paging networks. It uses a single slot in a standard 5U T800 rack frame. The T800-28-0000 is a rack frame specifically designed for paging transmitters and includes slots for the T801-20-0000 reference, a Paging exciter and Power Amplifier, a T8x5 link receiver and a Power Supply. Tait Electronics Ltd August 2002 T800 Paging Systems Page 4 of 4 3 Modem / Delay board The T800-37-0000 is used for two reasons: 1. To add a digital delay to the paging signal. This is used to compensate for the propagation delay for outlying paging transmitters on a wide area paging network. 2. To decode the modem tones used on an analogue link from the paging encoder to the remote paging transmitter. The delay is adjustable from 0 – 5 msec in 3.35 μsec (1 km) steps. The asynchronous modem is compatible with V.23 or Bell 202 modem standards and either 512 or 1200 bps rates. The T800-37-0000 fits inside of a T837-20-102x paging exciter. Installation is as simple as connecting the supplied ribbon cable to the paging exciter and selecting the required delay and data polarity using solder links. The T800-37-0000 is not fitted into the link transmitter; a separate modem is needed to convert the paging encoder data to V.23 or Bell 202 tones. T800-35-0000 Tait Electronics Ltd August 2002 T800 Paging Systems Page 5 of 5 4 Typical Wide Area Paging options Tait only manufactures equipment used between the paging encoder and the paging receiver. We do not manufacture encoders or receivers, as this is an already developed market with many manufactures providing cheep and reliable products. At the encoder end, you would need something like a Zetron Model 15 Encoder, which has a RS232 output. For wide area paging you need to connect this to a V.23 or Bell 202 modem before connecting it to your UHF link transmitter. We can supply a Slimline T800 for this purpose. At the remote end, a T855 receiver is used to receive the signal from the central transmitter. This is then decoded by the T800- 37-0000 modem board, which also adds the required amount of delay to the signal. The T801-20-0000 is used to generate the reference frequency, with the required offset. The T837-20- 1021 then takes all of this to make the paging signal, which is fed to the PA and antenna equipment. And with any luck the subscriber has their pager turned on and receives the message.

A T800 Series guide is supplied with each unit. The guide is located in the rack frame with four screws, two at the rear and two at the front, and the T800 unit is secured into the guide with two front panel mounting screws. A rear mounted N-type connector is used for RF input on the T835 receiver and RF out- put on the T836 transmitter, while the exciter RF output is via the front panel SMC con- nector. All DC, audio and control connections are via the rear mounted D-range connector. An additional rear D-range connector (T800-03) is fitted when remote mul- tichannel operation, or additional control or low frequency lines are required.

The system should be protected by the use of appropriately rated fuses in the power supply. Note:It is particularly important when the prime power source is a battery that fuses be employed in all supply lines. 1.4Reverse Polarity Protection A shunt diode is fitted to all T835 receivers, T836 transmitters and T837 exciters for pro- tection against connection to a power supply of incorrect polarity.

The lower guide rail is located in the rack frame with three screws, two at the rear and one at the front. The short upper guide rail is located with just one screw. The PA is secured into the guide with two front panel mounting screws. The RF input via the front panel SMC connector should be connected to an adjacent T837 exciter. The RF output is via the rear N-type connector, whilst all DC, audio and control connections are via the D-range connector. The guide rails will allow the PA to be latched in the extended position (refer to Figure 2.3). Caution:If continuous operation of the T838 is required, the rack module posi- tion immediately adjacent to the finned heatsink should be left vacant.
