Vision Fire & Security have added two new ISDN terminal adaptors designed to offer a higher specification connection method for the ADPRO range of video transmission products.
The ADPRO Standard TA is the low cost adaptor. The unit is smaller than the model it replaces but offers the same feature set and supports three main protocols: V.120 for use with FastVu and FastScan; X21 for use with FastScan; and Multi-Link Point to Point Protocol (MLPPP) which offers 128k operation with the FastVu transmission system. The ADPRO Advanced TA offers all of the features of the Standard TA but additionally is ready for RedCare Digital Support and has a facility for battery back-up. It also has a secure poll feature to provide protection of the link between the Terminal Adaptor and the FastScan transmitter. Commenting on the development, Tim Northwood, Sales Director ADPRO, said: ?These new adaptors are part of an ongoing research and development programme for our range of products.?
