Pelco C2624M manual Autonegotiation is enabled by default, Flow control is disabled by default

Using the TX Mode switch, you can do the following:

Enable autonegotiation or select (force) a specific data rate and duplex mode:

Enabling autonegotiation allows the FX82012 module to automatically negotiate with the device to which the port is connected for data rate and duplex modes of operation: 10 Mbps or 100 Mbps data rate and half-duplex or full-duplex mode. The highest common denominator of operational modes is automatically selected.

Autonegotiation is enabled by default.

If autonegotiation is not desired, you can select a specific data rate and duplex mode:

Data rate configuration allows you to select 10 Mbps or 100 Mbps.

Duplex mode configuration allows you to select half-duplex mode or full-duplex mode.

Enable or disable flow control. Flow control controls data transmission at the sending device to avoid overfilling buffers and losing data at the receiving device. When the buffers on the receiving device are full, a message is sent to the sending device to suspend the transmission until the data in the buffers has been processed.

NOTE: For time-sensitive data applications (for example, video and audio applications), it is recommended that flow control be disabled.

Flow control is disabled by default.

With the FX82012 module powered off, set the TX Mode switch to the desired modes of operation.

NOTE: TX Mode configuration must be set when the module is powered off. If you wish to change a TX Mode switch setting after the module has been powered on, power off the module, change the TX Mode switch setting, and then power on the module again.

Refer to Table A for TX Mode switch settings and corresponding 10BASE-T/100BASE-TX port modes of operation.
