PSTN V.92 19 inch Rack Our 19 inch rack modems can be stuffed with a Conexant based SM_H2 socket modem or an IMOD56 I-module whatever suits you better. With a unique design and a proven history of thousands of alarm points world-wide, the Proxima rack 19” PSTN modem rack with embedded SM_H2 or IMOD560 is a very stable, reliable and high performance communication system for various industrial applications.The development of PSTN Socket Modems and other embedded modem applications (like Imodules) is our core business since 1989. The PSTN modems that we design and produce are communication ready devices that integrate data/fax functionality into a very space-efficient, embedded modem design. We have embedded PSTN modems based on Conexant (former Rockwell), Silicon Labs, TDK and Analog Devices technologies and in socket modem format (64,5 mm x 26,5 mm) - a universal industry standard – or in I-module format (56 x 56 mm). Embedded Bausch socket modems like SM_H2 (Conexant) or I-modules like IMOD560 (Conexant) are used worldwide, integrated in all kind of devices that need to communicate such as embedded control systems, payment terminals, SIA or Contact ID based alarm transmitters, copiers, etc… This embedded modem technology platform is used in all our modems ranging from DinBox DIN rail modems, external Proxima desktop modems to Proxima rack modems which have to fit in a 19" Euro PSTN modem rack system.

Specifications
- Proxima 19 inch Rack system:
19" Euro rack with backplane, integrated Meanwell RS-50-5 power supply card (Input rating: 88-264 VAC, 47-63 Hz with fuse spec: 230V / 1A; current: 0.8A @230V, Output rating: 5VDC)
1 to 16 Proxima MRACK modems
Environmental requirements:
Temperature: Operating 0-40°C, Non-operating -20 to 80°C
Humidity : 20% to 50% (non condensing)
Physical dimensions:
Height : 132 mm (3 Units), Width : 480 mm
Depth : 280 mm, Weight : Approx. 9 kg with 16 modems
Modem front panel indicators and connectors:
6 x LED indicators : DTR, DCD, CTS, RTS, TxD, RxD; monitor port which can also be used / switched to take over the control over the front serial port (configuration) in stead of the back
RS-232 DB25 serial port; IDC 2,54 mm, 2x5 10P Male RS-232
serial local configuration port: can be used to connect 10P female to DB9 Female flat extension cable 28 AWG, 9 core, IDC 2,54mm.
Back panel connectors: 3-pin shroud Male (IEC320C13) to connect power cord
16 x RJ11 female connector to connect telephone cable; 16 x RS-232 DB25 Female connectors; with the switch above the front serial port it is possible to switch the terminal port connections from back to front. This makes it possible to connect a PC (laptop) for local configuration without having to remove the rack out of the complete system.
Racks are usually equipped with 16 x rack modems, connected to the Windows or Linux network environment by IP enabling multiserial-to-Ethernet convertors like Digiport TS16 Portserver for easy configuration and management.
A LED in front of the rack indicates the presence (ON or OFF) and good functionality of the Meanwell RS-50-5 power supply card. - PSTN rack modem in Euro card format with SM_H2_3V3_V:
