LAN/GPIBゲートウェイ使用例

Keithleyの例とほとんど同じなので、要点のみ

LAN/GPIBの先にAgilent製の周波数カウンタ（Agilent 53181A）をGPIBアドレス22で接続した場合を例に挙げる。

作業ディレクトリ作成

pfrproc2:~ % mkdir /users/obina/epics/app/AG53181A

pfrproc2:AG53181A % makeBaseApp.pl -t ioc AG53181A
pfrproc2:AG53181A % makeBaseApp.pl -i -t ioc AG53181A
The following target architectures are available in base:
    linux-x86
    linux-x86_64
What architecture do you want to use? linux-x86_64
The following applications are available:
    AG53181A
What application should the IOC(s) boot?
The default uses the IOC's name, even if not listed above.
Application name?
