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).

Assembly Instructions
Note: Customer supplied required parts and tools:
• power cable
• cabinet ground wire
•ohmmeter
• RJ-11 phone cord
1. Turn off the main AC power supply. Connect the AC power cable to the AC power
connection on the power supply marked as N and L1.
2. Connect the power transfer cable to the power supply and modem as follows:
• +V on power supply to terminal 2 (+) on modem using clear wire.
• –V on power supply to terminal 3 (-) on modem using black wire.
Connect the ground on the modem to the cabinet ground (wire not provided).
3. Turn on power to the power supply. Connect modem programming cable to modem’s
DB-9 connector and then to an available port on a PC (eg. Com 1).
4. Configure external modem. See detailed instructions on page 6.
Disconnect the programming cable when finished.
5. Connect the Siemens Milltronics product to the external modem using the
appropriate wiring code (see Configuring Instruments on page 9).
6. Program the Siemens Milltronics product using the correct parameters listed in
Configuring Instruments section. Connect external modem to analog phone line
using RJ-11 telephone cable in the modem’s line jack.
7. Configure the internal modem in laptop or desktop PC using Windows 95 or 98 to
communicate using Modbus RTU protocol. (See Configuring Internal Modem on
page 17.)
8. Dial in to Siemens Milltronics product using internal modem.
Note: When modem and power supply are mounted in an external enclosure,
ensure they are not exposed to the elements, dust, or debris.

•Modbus RTU
•8 data bits
•1 stop bit
• no parity
• no flow control
