Description
Each PC Microcontroller in the 6000 Series has two serial ports, except
for the 6030 which has 4 serial ports. These serial ports are 16C550
compatible. They can be used for interfacing to a printer, terminal, or
other serial device. These ports support 5-, 6- 7-, or 8-bit word lengths,
1, 1.5, or 2 stop bits, and baud rates up to 115.2 KB.
The serial ports meet IEC1000, level 3, ESD protection specification
with ±8 KV of ESD protection. Backdrive protection is also included.
COM2 can be converted to optically isolated, RS-422/485 with the
network interface module (NIM). NIM mounts directly onto the PC
Microcontroller without the need of a cable or external power supply.
Note The Network Interface Module (NIM) is not compatible with the 6010
PC Microcontroller.
Use a VTC-9F cable to connect the ports to external serial equipment.
The pinout of the connector allows you to plug the cable directly into a
9-pin PC serial connector (refer to the product-specific appendix for the
connector pinout). When interfacing the PC Microcontroller to your PC,
you will need to use a null modem adapter. The serial port at COM1
defaults to IRQ4 at I/O address 3F8H, which is the PC standard for
COM1. Likewise, the serial port at COM2 defaults to IRQ3 at I/O
address 2F8H. Refer to Table 5-1 for the connector designation of each
COM port on your model in the 6000 Series.

Selecting console devices
The PC Microcontroller has two options for console devices:
1. Serial console from COM1, as selected with the SETUP program (“Serial
Console on COM1: ENABLED”). A serial cable/null modem adapter
plugged into a host PC running PC SmartLINK provides both input and
output. The local keyboard allows input.
