CPUs and the s for the other two are on the s’ front panel labed Port and Port . The CPU and serial ports are configurab using the programming software configuration function. Ea port can also be configured using a M_REQ. For details about using these ports and about the M_REQ instruction pase see publication Serial . Serial Port Front Panel s Port the p port is RS patib. This port has a pin RJ . This has fe contacts and is similar lar jacks monly used for phones and modems. The ICCBL can be used access this port providing a direct connection an RS device without the need for a converr. See apr for a datasheet on this cab. Port the botm port is RS patib. Access Port is through a pin D that has fe contacts. Serial Port Status Ds The CPU and CPU have three Ds that indica the status of serial port activity on the CPU. The SNP D on the CPU and CPU is cald PS Port on the CPU. This refers the port that uses the serial on the ’s power supply. This D flashes when data is being transferred through the port. It reins off when the port is ictive. The P D will flash when data is being transferred through Port the RS port. It reins off when the port is ictive. The P D will flash when data is being transferred through Port the RS port. It reins off when the port is ictive. Q apr CPUs Procols Suppord Starting with Firmware Rease . breakfree SNP became the default procol on the three Serial Ports on these s. See Breakfree SNP Procol on page for details.
