In a terminal emulator mode, you may not see the echoed characters on your display when issuing
commands that have a response, because the echoed characters may be overwritten by the response.
The

which a host computer communicates to the "master" Gem6K drive over RS-232 (COM2 port) and the
master Gem6K drive communicates over RS-485 (COM1 port) to the rest of the units on the multi-drop.
For this configuration, the echo setup should be configured by sending to the master the following
commands executed in the order shown. In this example, it is assumed that the master's device address is
set to 1. Hence, each command is prefixed with "
....... Subsequent command affects COM1, the RS-485 port
1_PORT1
....... Echo characters back through the other port, COM2
1_ECHO2
....... Subsequent command affects COM2, the RS-232 port
1_PORT2
....... Echo characters back through both ports, COM1 and COM2
