The SR-2 allows two control systems to have access and control of a product with a single RS-232 port. Communications

through Port A or Port B will be sent to the Master Port. When the product responds through the Master Port the

communications will be sent to both Port A and Port B. Please note that the SR-2 only has RX, TX and Ground signals

and is capable of transmissions speeds up to 460800 baud.

The following diagram shows the connector pins used for each of the SR-2 connections.

A typical installation will use a modem cable (straight through connections) between the controller and

the SR-2. The SR-2 Master Port is designed to connect directly into a modem port on a product to be

controlled.

In the case where you need to control an Avocation Systems A/V Routing product the master port will

need a null-modem adapter between the Master Port and the Avocation product.
