    The command name can be from 1 to 7 characters long. Command names will be specific to device types. In other words, the EF2280 has its own command set, which is different from the EF2241's, which is different from the EF1210's, etc. There are some commands, such as 'PING', that are common among all the various command sets.

    IDs 3 and 7. The EF2280's will respond with 'F03GAINIA10' and 'F07GAINIA10', respectively. Now, someone uses the front panel of the EF2280 set to ID 7 to decrease input A's gain by 1 dB. When this happens, the EF2280 will respond with 'F07GAINIA9'. This example illustrates that status messages can be sent as the result of an RS-232 command or as the result of some other change in the Vortex device such as front panel adjustments, logic inputs, etc.
