Model 5 Encoder

The Zetron Model 5 Communications Encoder is a compact low-cost desktop paging encoder for selective calling of two-tone and five-tone sequential pagers. A 12-digit high-quality keypad allows for manual entry of pager codes. A four-digit display indicates the number of the pager being called. The pager number remains on the display after the paging sequence is complete, allowing immediate re-page without reentry of the pager number. Three LEDs indicate when the encoder is paging, transmitting, and when the microphone is open for the voice transmission to tone-and-voice pagers.
The voice transmission can be made through the built-in electret microphone or through a normal desk microphone. The built-in microphone, which can also be used to make voice broadcasts over the transmitter, is equipped with automatic gain control for optimum voice pick-up. An additional feature for tone-and-voice pagers is an alert tone, which when selected, precedes the voice message to notify the recipient that a voice message is to follow. A choice of alert tones is provided. (For custom or Plectron pagers, use Zetron Model 15P.)

CONFIGURATION AND FEATURES

The Model 5 contains several programmable features to aid in system customization. By entering a special code on the 12-digit keypad, the encoder can be placed in the programming mode which allows the encoder to be configured for each type of pager being used.

For two-tone paging, the call size can be set to 100 or 1000, eliminating the need to enter one or more leading digits of the pager number. Tone groups can be selected for the 100-pager call size, or code plans may be chosen for the 1000-pager call size. The Model 5 can also signal five-tone pagers. The call size for fivetone pagers can be set to 100, 1000, 10,000, 100,000 or 1,000,000 cap codes. The tone series can be set to EIA, CCIR, or ZVEI signaling formats. The programming mode also allows the selection of several features that enhance operation of the encoder. Such features include transmitter keyup delay, talk time duration, auto page, and internal/external microphone.

The keyup delay, to ensure that the transmitter is fully keyed before the first tone is sent, can be set to any value from zero to 2 seconds, in 0.1-second increments. The talk time duration for the voice portion of the transmission can be set to anywhere from zero to 59 seconds, in one-second increments. The talk time can be extended as necessary beyond the selected value by holding a key on the keypad or the PTT switch on the desk microphone. Power is provided by a 12-volt wall transformer or the transmitter�s +12V DC supply may be used. An optional 220V AC transformer is available.
