3.4. Communicating with the APS-16 Unit


Perform the following procedure to enter the Command Mode, explore the unit's basic features, and check for proper operation.

1                     Start your communications program (e.g. ProComm).

2                     Issue the "Wake Port" command to access the Command Mode and make certain the port is ready to receive commands. Type /, then simultaneously press [Ctrl] and [E], and then [Enter] (/^E [Enter]). The "APS>" prompt should appear.


a) If you are performing this overview via modem, please refer to Section 5.1 for additional instructions.

b) If the "APS>" prompt is displayed, you have successfully accessed the Command Mode.

c) If the "APS>" prompt is not displayed, this may indicate a communication problem. Check the following:

•                      Cable Connection: Check the cable connection between the APS-16 and the PC. Make certain the cable connectors are firmly seated.

•                      Communication Parameters: Make certain the APS-16 and ProComm are using the same parameters.

1                     Type /S [Enter] to display the Status Screen (Figure 3.2). The Status Screen summarizes conditions at all Ports. The various fields of the Status Screen are explained in Section 8.4.

2                     Port Connection: The APS-16 can perform two different types of port connections; Resident Connections and Third Party Connections.



a) Resident Connection: Your resident port (e.g. Port 1) issues a /C command to connect to a second port.


b) Third Party Connection: Your resident port (e.g. Port 1) issues a /C command to create a connection between two other ports.

i. To connect Port 2 to Port 3, type /C23 [Enter].

ii. While Ports 2 and 3 are connected, Port 1 will still recognize APS-16 commands. Type /S [Enter] to display the Status Screen. The "STATUS" column should now list Ports 2 and 3 as connected, and Port 1 as "Free".

iii. Issue a Third Party Disconnect command to disconnect Ports 2 and 3; type /D 2 [Enter]. The unit will display the "Are you Sure (y/n)?" prompt. Type y and press [Enter] to disconnect.

iv. Type /S [Enter] to display the Status Screen. The "STATUS" column should now list Ports 2 and 3 as "Free".

6. Define the Site I.D. Message to indicate the name or location of the unit. The Site I.D. cannot include non-printable ASCII codes such as nulls and Line Feeds.

a) Type /F [Enter]. A prompt will appear. Key in the desired text (up to 32 characters) and press [Enter].

b) To display the Site I.D., type /J [Enter].

c) The Site I.D. will be cleared when the unit is initialized.

This completes the introductory overview of the APS-16. After you have determined that the unit is operating properly, configure the unit as described in Sections 4 and 5.
