When speaking to most RS-485 or RS-232C based devices, the remote modem must be programmed for
the communication to work. This task is often quite complicated because modems are quirky when talking
to remote devices. To make this task easier, EIG has designed a
Modem Manager
RS-485 to RS-232C
converter. This device automatically programs the modem to the proper configuration. Also, if you have
poor telephone lines, modem manager acts as a line buffer, making the communication more reliable.
