Current Loop
Current Loop
Current loop can support a signal up to 1,500 feet. As an alternative to RS-232, current
loop is supported by some terminals and serial printers. SWAN, AWAN 3883, and
AWAN 3886 (16, 32) require external adapters to support current loop. An
HP-designed RS-232 to current loop converter (T3886CL) is available for AWAN
3886-16 and AWAN 3886-32 models. See Figure 2-12 on page 2-31.
FASTP Print Process
Because FASTP added its own device support and relied on nearly no device-specific
actions within the I/O process, FASTP has become the basis for other print processes
that use networking and remote FASTP spooling protocols (XNS for Xerox, SMB, and
NetWare). The most successful of these print processes has been FASTPTCP,
introduced in the D30 RVU, which is supported on G-series systems and supports a
wide variety of protocols and devices, including AWAN servers.
FASTPTCP is a Spooler Print Process that supports a wide-range of network printers
as well as printers connected to print servers and terminal servers. Protocols
supported include HPJetDirect, Lexmark, Microplex, LPD1179, TELNET, and “raw”
TCP. AWAN 3883/4/5 access servers and 3886 AWAN server models include
enhanced support for FASTPTCP TELNET protocol. Special support is provided for HP
TTAP and HP PCL printers.
The following FASTP network print processes are:
•
FASTPTCP for TCP/IP LANs (T8932)
•
FASTSMB for SMB LANs (T9146)
•
FASTPNOV for Netware LANs (T8924)
•
FASTPX25 for X.25 WANs (T8934)
•
FASTPXNS for XNS LANs (T8931)
See the Spooler FASTP Network Print Processes Manual and the Spooler Utilities
Reference Manual for more information.
Printers
Many printer models are approved for use with the NonStop S-Series system. See
your HP representative for more information about recommended printers. The
following printers are supported: 5524, 5525, 5526, 5527, 5528, 5529,5530, 5531, and
5532.
