INSTALLING SB SOFTWARE AND HARDWARE
If SB hardware and software are purchased entirely from Merrick, it comes installed and
configured along with a specification sheet. The configuration may have to be altered as the
system changes. When an A-B 1771-DXS2 or A-B 1771-EIP Information Processor is used, the
software and configuration files resides on a PCMCIA Flash EPROM card. Merrick has to do the
installation for the 1771-DXS2, since a BIOS upgrade in the 1771-DXS2 Information Processor is
necessary.
SB will run on a generic PC according to Hardware Requirements (page 2). If configuration data
was available to Merrick before the time of shipment, the configuration file has already been
prepared. In any case, a specification sheet is always shipped, indicating the current
configuration.
Install the KT Card, if used
Configure and install the 1784-KT/B card in the SB host PC, according to instructions in [2]. Since
SB normally is the only application running on the host PC, it is recommended that the default
settings are used, that is,
• Memory address: D400 ([2], page 8)
• Interrupt Setting: IRQ 5. ([2], page 9)
This corresponds to an address switch setting of {Down, Up, Down, Up, Down, Down}, and the
Interrupt jumper in the center position.
If there are other devices that may cause a conflict with these settings, other settings can be
examined. The corresponding configuration files (CFG_KT.INI and CONFIG.SYS) must me
altered accordingly. See Modify PC configuration (page 5).
Install the KTX Card, if used
Configure and install the 1784-KTX card in the SB host PC, according to instructions in [9]. Since
SB normally is the only application running on the host PC, it is recommended that the default
settings are used, that is,
• Memory address: D700 ([9], page 2-3)
• Interrupt Setting: IRQ 5. ([9], page 2-7)
If there are other devices that may cause a conflict with these settings, other settings can be
examined. The corresponding configuration file (CFG_KT.INI) must me altered accordingly. See
Modify PC configuration (page 5).
Install RS-422 converter or adapter, if needed
If the host PC does not have a RS-422 serial port, a converter between RS-232 and RS-422
must be used. Alternatively, an internal RS-422 adapter board may be used. Make sure to
disable the corresponding RS-232 COM port!Merrick has successfully tested the ULTRA-485
serial port adapter from Industrial Computer Source, [phone]. Strappings for COM 1 for
this board are:
• Port Adress to 3F8. SW1 = {On, On, On, Off}
• IRQ Jumper to IRQ4. E1 = {Jumper @ 4} Do not use IRQs higher than 7.
• Single Interrupt mode. E2 = {Jumper @ N}
• RS-422 mode. E5 = {Jumper @ 422}
• RS-422 mode. E3 = {Jumper @ 422}
