The External Modem Kit
The External Modem Kit is assembled to assist users connecting external modems to
Milltronics brand products. While any modem can work with Siemens Milltronics brand
products, the VT-Modem by SIXNET is easy to use and reliable. For best results, use the
RS-232 Modem Kit for the PC side and RS-232 and RS-485 Modem kit for device side.
When connecting to the OCM III, Siemens Milltronics recommends using Flow Reporter
software. When working with Modbus RTU, we recommend the Modbus Serial driver by
Kepware (www.kepware.com).
