4 Communication 52 4.7 Installing and Using the External Modem Uses of the External Modem Where a network is not available, you can connect an external modem to the CFR’s RS–232 port. The modem lets you: • Program the CFR to send an alarm message to a remote host via the telephone line when a power event takes place. • Dial up the CFR for remote monitoring or control. Once connected, all RS–232 menus are accessible.
53 4 Communication 4.7 Installing and Using the External Modem (Continued) Step 1: Enable the CFR’s Modem Feature The CFR is shipped with the modem feature disabled. To enable it: 1 Connect a computer to the CFR’s RS–232 port (Sections 2.9, 4.1). 2 Go to Menu Item #52 (Figure 4.19). (For explanations of each item see “Modem Setup and Control: Sub Menu #52” in this section.
4 54 Communication 4.7 Installing and Using the External Modem (Continued) Step 2: Connect and Configure the Modem Use a shielded, null-modem serial cable, DB–25 male to DB–9 male, to connect the modem to the CFR. 1 The most common ways to connect the cable are: • A null-modem cable with DB–25 male to DB–-9 male ends (Figure 4.20). • A null-modem cable with DB–25 male to DB–25 male ends and a 9–25 adapter. • A standard straight-through cable with DB–9 male to DB–25 female and a nullmodem adapter.
55 4 Communication 4.7 Installing and Using the External Modem (Continued) 3 The initialization string (Item #527) is a set of commands the CFR sends to the modem to initialize it. For a US Robotics modem, the string is: • ATX4Q0V1&H0&R1&I0&B1 Where: • X4: Extended set of result codes. • Q0: Result codes are displayed. • V1: Display verbal (words not numbers) result codes. • &H0: Disable transmit data flow control (neither hardware “CTS” nor software “Xon/Xoff” flow control).
4 Communication 56 4.7 Installing and Using the External Modem (Continued) Step 3: Initalize the Modem To initalize the modem start a CFR self test (Section 3.3). The CFR must initialize the modem. If a remote host calls before initialization, the CFR/ modem combination will not answer the call. TIP: If the modem is set for auto answer and a call is answered before the CFR initalizes it, the modem uses its own baud rate which may not be the 1200 baud used by the CFR.
57 4 Communication 4.7 Installing and Using the External Modem (Continued) How the CFR Sends Alarms To send an alarm, the CFR sends the dial command to the modem and waits up to 60 seconds for a “connect.” If this fails, it will try the same dial command two minutes later if the modem responds back to the CFR with a “No Carrier,” “No Dial Tone” or “Busy” messages. If the modem does not respond (it is disconnected, not powered or is inoperable), the CFR tries to initalize the modem.
4 58 Communication 4.7 Installing and Using the External Modem (Continued) Ex t er n al Mo d em Set u p Men u s 520 E n ab l e A u t o m at i c A l ar m s Enable this feature near the end of the configuration session since the CFR will try to communicate with the modem two minutes after this feature is activated. When set to "Yes," this causes the modem to dial out and report a problem when it occurs (see Item #522). The default value is No.
59 4 Communication 4.7 Installing and Using the External Modem (Continued) Ex t er n al Mo d em Men u Set u p Men u s (Co n t in u ed ) 523 Set In v er t er A l ar m D el ay Setting this delays the transmission of "UPS003-Inverter on" messages for 1 to 5 minutes to prevent short interruptions in the line from being displayed. Setting it to 0 causes the immediate sending of the message.
