Chapter 1. Introduction PM-1004-R20 driver & User’s manual is the same as PM-1004. The PM-1004-R20 is a PC/104-compliant 4-port RS-232/422/485 module. The PM-1004-R20 has a high performance serial I/O chip TI TL16C554A on board. Its UART is compatible with the 16C550. The PM-1004-R20 provides two ways of interrupt control mechanism - shared or independent IRQ. Besides, its IO address and interrupt status address are also selectable by jumpers. 1.1 Specifications Bus: PC/104.
1.2 Package Contents The following items will be found in the packaged contents: 1 x PM-1004-R20 1 x Serial port RS-232 cable (40 pin, 4 DB-9 ) 1 x RS-422/485 cable (16 PIN, 4 DB-9 ). 1 x DRIVER CD-ROM 1 x User manual If any of these items are missing or damaged, please contact the dealer who you purchased the product from. Be sure to save the shipping materials and carton in case you want to ship or store the product in the future.
Chapter 2. Installation This chapter describes how to install the PM-1004-R20. 2.1 Hardware Installation To install the PC/104 modules, please follow the instructions below. Note: Please ground yourself to remove any static charges before touching your PM-1004-R20. You can do it by using a grounded wrist strap at all times or by frequently touching any conducting materials that is connected to the ground. 1. Turn the power off 2. Plug the PC/104 module into the connectors on the CPU card. 3.

2.3.1 Interrupt Status Register Setup (S1,Vector Address) When data arrives at one of the four ports, it will generate an interruption in the interrupt register. The PC software can read this, and identify immediately which port generated the interruption. This saves time, and makes programming easier. When a data bit of the interrupt status register is set to 1, the corresponding channel is selected to generate an interruption. If the bit is 0,then no interruption is generated.
