Kramer VS-3232VXL

Before using the ASCII protocol, you need to select it from the
machine’s front panel. Press the MENU button until you get to “set
communication protocol” and then choose the ASCII protocol. This is saved
in the non-volatile memory, so the machine will remain as ASCII even after
cycling power. To check that the protocol has been selected, and to confirm
that the communication is OK, send the" Connection Status" comnad to the VS-3232Vxl. It
should reply by sending back the string OK!!
