To communicate with the relay through a PC, connect the relay to a serial port of an IBM-compatible computer with a
null-modem cable. Connection can be made either to the 25 pin D-connector on the back of the relay (PL2A), or the 9 pin
D-connector on the front (PL1). Cable diagrams are shown in the following:
• Figure 8–2: MODEM CABLE on page 8–23
• Figure 8–3: 25-PIN NULL MODEM CABLE on page 8–23
• Figure 8–4: 25-PIN NULL MODEM CABLE on page 8–27
• Figure 8–5: NULL MODEM CABLE FOR PORT PL1 on page 8–27
The communications software required to access the relay, ALPS-Link, is included on the enclosed Products CD. Follow
instructions in Section 11.1.5 SOFTWARE INSTALLATION on page 11–3 to load ALPS-Link onto the PC.
The ALPS relay requires the use of passwords to obtain information from the relay, to change Settings, or to perform
Actions. The relay is shipped from the factory with the following communications passwords:
VIEW: VIEW!
SETTINGS: SETTING!
ACTIONS: CONTROL!
MASTER: MASTER!
The exclamation point following the letters is part of the factory password. The factory passwords MUST
be changed before the user can modify Settings or initiate Actions. The user can log into the relay at any
NOTE
password level. After logging into the relay, the password can be changed under the ACTION menu by
selecting CHANGE PASSWORD.
The user must logout from the ALPS before changing another password. The remaining passwords can then be changed
by logging into the ALPS using another default password. The communications passwords may be viewed, in an encoded
format, via the [INF] (information) key.
To log into the relay, follow the instructions in Section 4.1.9: USING COMMUNICATIONS (OPTIONAL) on page 4–4. Any
one of the factory passwords can be used to log on to the relay. The relay UNITID (General Setting 101) is factory set to
"0".
