Installing the Adapter
2. Verify the Network Baud rate, which is set by the network master
and depends on cable length (see Glossary).
The 22-COMM-P adapter uses the Auto-Baud function, which
enables the adapter to recognize the present baud rate and
automatically sets itself to the transmission rate used by the master.
The adapter supports the following data rates: 9.6 Kbps, 19.2 Kbps,
45.45 Kbps, 93.75 Kbps, 187.5 Kbps, 500 Kbps, 1.5 Mbps, 3 Mbps,
6 Mbps, and 12 Mbps. After detecting the correct baud rate, the baud
rate that was found is monitored continuously.
3. Set the byte SWAP Jumper J3, which determines the Intel or
Motorola (position SWAP) data format, depending on the
corresponding PLC. (see
4. Verify the adapter Mode Jumper J2 is in “1X” for Single mode
operation or in “5X” for Multi Drive mode operation (see
and setting descriptions below). For complete details on Multi-Drive
mode operation, see
J2 Jumper Setting
Description
Figure 2.1 Position A
(or jumper missing)
Sets the adapter for Single mode of operation (default setting)
using a single drive connection.
Important: In this mode, connections to multiple drives must
be removed since all powered and connected hosts will
respond to any message sent by the adapter.
Figure 2.1 Position B Sets the adapter for Multi-Drive mode of operation using up to
5 different drives. DSI peripherals do not operate with the
adapter in this mode.
