PEM-340
Operation Manual
9-2. RS-232C Control
The PEM-340 provides support for RS-232C communication through the SIF connector on the
front panel. The RTDX (transmit) terminal of the PEM-340 should be connected to the receive
terminal of the external device (e.g. computer). The RRDX (receive) terminal of the PEM-
340 should be connected to the transmit terminal of the external device. Please ensure that the
handshake line on the external device is closed. The terminals for the SIF interface (Hirose
Electric HR10-7P-6S) are listed below:

9-1-2 GPIB function
GP-IB has 10 kinds of interface functions, each of which has its grade that is called
its subset. A "0" after the symbol of each function shows that support is not made,
and each numeric value represents grade.
