Slave Mode Operation / Examples
This chapter describes how to operate the DL50 in the slave mode. The slave
mode is the normal operating mode of the DL50. In order to show the
operation of the DL50, this chapter contains example messages and host
programs.
To operate the DL50 in the slave mode, perform the following steps:
1. Install the DL50 as described in Chapter 4.
2. Configure the DL50 using the configuration DIP switches as shown in
Figure 3.2. You can configure the DL50 using the DIP switches before or
after installation. Make sure you press the reset button (or cycle power) if
power is applied before you configure the DL50. This will load the DIP
switch settings into the DL50’s memory. Refer to Figure 2.2 for the
location of the reset button.
3. Depending upon the protocol selected using the DIP switches (Simplex or
Duplex), send message packets which are in the format described in
Chapter 5.
4. If you are using Duplex Protocol, the host device will receive an ACK
(decimal 6) or NAK (decimal 21) response from the DL50. Refer to
description of DL50 response format in NO TAG. The host should
re-transmit the message if a NAK is received.
The following are example message packets that could be transmitted to a
DL50. The function(s) of each command is provided.
