interconnect subsequent shelves. Each shelf controller should be assigned unique sequential shelf addresses. No connection should be made to the RS422 in connector on the shelf containing the E220
4. FACEPLATE FEATURES
The terminal interface operates at a data rate range of
4.8kbps to 19.2 kbps. The asynchronous data format is fixed at eight data bits, no parity, one stop bit. The supported terminal type is VT 100, or compatible.
Optional terminal parameters should be set as follows:
