Mobile pager test device PS 622

The PS622 testing device is a handheld device and is intended to use for testing mobile pagers. It supports POGSAG and 5-tone signalling.

All parameters can be set directly on the keypad. Furthermore, the PS622 can be controlled comfortably using the integrated USB-interface on a windows computer. The device features and configuration can be displayed and programmed using a user-friendly software-interface.

Customized text elements to be used for POCSAG-pagers or status signals from the FMS-radio system can be easily stored directly in the device.

The modulation connector offers control signals for special metering and testing setups.

The PS622 is the ideal tool for maintenancing and testing pager devices following e.g. reprogramming or repair.

Dispatch Center device GA 596

NRS 232 - miniature emergency emitter for alerting and remote control

The NRS 232 is a miniature emitter and is used for alerting or remote control purposes in combination with radio-receivers working on POCSAG-protocol (e.g. LX2, LX4, remote control device PFS141).
Field of operation: silent alert, e.g. in hospital or prison. The device is driven by a Lithium-battery. Charge status is indicated by a LED on the device or via radio transmission the the dispatch center. Highly reliable due to repeated transmission.
