3-DCD 232 In this mode, certain I/O devices can wake up when the DCD signal is asserted and turn off when the signal is negated. If you select this option, the DCD 232 menu appears for you to set the Pre-Data DCD Time and Post- Data DCD Time.

Setting the Pre-Data DCD Time

1.Select Serial DCD Mode ä Pre-Data DCD Time.

2.Enter the number of milliseconds it takes for the device to wake up after the modem asserts the line. The value must be a 3-digit number. The post-data time value sets the number of milliseconds it takes for the device to turn off after the modem negates the line

Setting the Post-Data DCD Time

1.Select Serial ä DCD Mode ä Post-Data DCD Time.

2.Enter the number of milliseconds it takes for the device to turn off after the modem negates the line. The value must be a 3-digit number.

6.4.Data Setup

Setting the Maximum Packet Size

1.Select Network ä Max Packet Size.

2.Enter the largest amount of continuous bytes of user data you expect in a single transmission. The value must be in the range 1 ￿ 1023.

Note: The Packet Mode affects how much user data can be in a packet. For Enhanced Telemetry and Mobile Data modes, the maximum will be less than 1023 due to memory constraints. The Max Packet Size window displays the actual value for these two modes.

Setting the Packet Mode

1.Select Network ä Packet Mode.

2.Select from the following options:

1-Basic Telemetry This mode uses a simple Cyclic Redundancy

Check (CRC) for error detection.

2-Enhanced Telemetry This mode is similar to Basic Telemetry mode, but it includes Reed-Solomon forward error correction.

3-Mobile Data

This mode uses forward error correction and
