PROTOCOL CONVERTER MODEL A/S-4
58
8.4 Batch Default Options
The A/S-4 has the capability of loading all it’s Batch options from the VDU (computer) without going
through any menus. This is done by receiving the shift out (X’0E;) character followed by the options
selected in hexadecimal form. The VDU and A/S-4 must be set to receive and transmit an 8-data bit
word with no parity, so all 8 bits of the hexadecimal characters are received. Once all the new Batch
default options are loaded, the A/S-4 is then automatically set to run in the Batch 3776/77 mode. Below
is the Batch options with its bit location.
