INTRODUCTION

The Hydra is an interface device that allows the connection of multiple cash
register terminals using the Regcom/Networker/Vnetworker slave units for
the purpose of transaction logging.

The Hydra receives RS-485 data from the Regcom/Networker/Vnetworker
networks and converts this to an RS-232 format that DVRs or the VSI-Pro can
read.

CONNECTIONS

The Hydra uses a bi-directional 2-wire RS-485 data bus to communicate to the
slave devices. The device at each end of the network must be terminated. An
8-DIP switch on the rear of the unit is used to set the termination. Switch No.
8 is the terminal switch. When set to ON, the device is terminated. When set
to OFF , it will be un-terminated.
