PO-4S – 4 port serial
Serial models have 2 options:
This manual contains information for the installation and operation of the Porter, Rose Electronics' name for its series of code activated switches. The Porter consists of a switch unit and a separate wall mounted power adapter. You have chosen a versatile microprocessor controlled switch that allows a computer to access serial devices such as modems or instruments. The selection is through a code that is transmitted intermixed with the normal data to the device. Since the Porter has buffer memory, each device may simultaneously load data into the unit. The serial models allow different baud rates and protocols to operate independently on each port with full duplex communications. All equipment is connected by cables to the Porter's rear panel. The unit's external power adapter connector and on/off switch are also n its rear panel. The Porter's front panel has 13 LEDs which display status information and switches which are used to manually control the unit and run the unit's diagnostics.
One computer to many peripherals Compatible with any computer – PCs, Macs, minis Compatible with all printers and plotters Simultaneous inputs from all computers Up to 256K buffer Serial (RS232) or parallel (Centronics) Models for either four or eight devices Advanced features for trouble-free performance LEDs show data activity and status Self-text and diagnostic features Made in USA
The Porter is available in several models, 4 or 8 channels, serial or parallel, and with a 16K base buffer (Expandable to 256K). The model numbers are:
PC-8S – 8 port serial PO-4P – 4 port parallel PO-8P – 8 port parallel /B buffer options = 64K or 256K

Congratulations! You have chosen one of the best code activated switches on the market. The paragraphs below summarize the steps to integrate the Porter into your environment.
You should have received the Porter system unit, a power adapter, and this Porter installation and operations manual. If additional cables were ordered, they usually arrive in the same package.
Cabling is one area you should pay careful attention to. Consult the cabling guides in this manual for the correct pin outs. If you need assistance, contact our tech support, we will be happy to assist you.
The Porter is a versatile unit. It can be configured to match the type of equipment that you have. To configure the switch requires connecting a computer or terminal to the configuration port on the porter – port 0.
If you have a PC, then you run a terminal emulation program to setup the Porter. The parameters are saved in the Porter. From time to time as you change the configuration of your equipment, you may need to adjust the configuration of the Porter. You do not have to have a PC to use the switch or configure it.
The final step is to make sure that your computer's software is configured to access the features of the Porter. This involves setting up the proper communication settings for serial ports and providing a method to issue commands to the Porter. The commands are typically issued from PCs by user software or from batch files. If you use serial ports on PCs, it is required to setup the AUTOEXEC,BAT file with the proper DOS MODE statements.
Well we certainly hope all goes well with your installation, but if there is a problem, we are only a phone call away. If you have already installed the switch and something is not right, it can be helpful to be at the switch location and at the computer connected to port 0 on the Porter when you call. The front panel of the Porter is very useful to diagnose problems that can occur.
We would like to think that you would read the rest of this manual, it may not be the most exciting reading material, but at least scan through it for the key points. Use it to get the correct cabling information. Thank you for choosing Rose Electronics and the Porter.

1. Connect your computer terminal to port 0 with the proper cable.
Refer to Appendix B for a list of common cables
2. Connect the power adapter, turn on the unit, power LED = Green
Power-up sequence test will start
3. If the serial factory default protocol of 9600 BAUD, no parity, 8-bits, 1-stop, and DTG
flow control for all ports is acceptable, skip step 4.
4. In this step, you will be shown a quick method of configuring the Porter. For
additional help, refer to the "Configuration" section for more detailed information.
a. Connect a computer (running a terminal emulator communication program such
a Procomm, or MasterLink supplied by Rose Electronics) or a dumb terminal to port 0 on the Porter. Set your computer or terminal to 9600 baud, no parity, 8 bits, 1 stop bit, and full duplex.
b. Send ESC@S to the Porter. The MODE, DATA, and BUSY LEDs will light, the
configuration menu will appear.
c. For this step, you will be prompted to enter a choice of menu select numbers
(followed by a carriage return) for the item you wish to configure. You will be prompted for all the proper responses. Enter 1 to change the protocol of any port. Enter 7 to save the changes. Enter 8 to exit the configuration menu. A configuration termination message appears, and the MODE, DATA, and BUSY LEDs will go out. Note that you must save your changes before exiting the configuration menu or they will be lost when you do step D.
d. Turn off the Porter.
5. Connect the Porter's ports 1-4 (or 8) to your devices with the correct cables.
Connect your computer to port 0. Cables must be wired correctly according to the section on cabling.
6. If the Porter is not already on, power it on. The LEDs will sequence through power
up tests.
7. Send data from your application or print program. Data will be routed automatically
to the current connect port
8. Read this manual and use the configuration procedure if you want to change the
prefix, power-on connect port, or the broadcast group. See the section on "Configuration" for further information.

1. Cable your devices to ports 1-4 (or 8) with a straight-through cable that has male
Centronics connectors on each end.
2. Cable your computer to port 0 with your computer standard parallel Centronics cable.
3. Connect the power adapter and turn the unit on. The power light should glow green.
The LEDs sequence through the power up tests. The ERROR LED will be on for any errors. See Tables II and III for the LED sequences.
4. Send data from your application or print program. Data will be routed automatically
to the current connect port.
5. Read this manual and use the configuration procedure if you want to change the
prefix, power-on connect port, or the broadcast group. See the section on PORTER COMMANDS for further information.
If you have a serial Porter, you must make sure that you set up your serial port for the correct baud rate and LPT1; redirection (if necessary). Redirection refers to the ability for data sent to a parallel port to be sent to a serial port instead. Dos has a command (the MODE command) to do this. So, for example, if you will be using the factory default protocol of 9600 baud, 8-bit word length, no parity, and 1 stop bit, then you need to include in your AUTOEXEC.Bat file the following statements:
MODE COM1;96,N,8,1,P
MODE LPT1:=COM1
Your application software must be set up to match the setting of the port on the Porter that you will be using. If you will be using redirection, you must install your program(s) to use the parallel port; otherwise, the setting of the serial port must exactly match the setting of the Porter's port that you will be using. Many of today's software packages have a flexible method of printing such as using the settings from the DOS MODE command or a configurable printer setup. For these programs, setting up the program to use the parallel port, and then redirecting LPT1 to COM1 using the DOS MODE command is the simplest method.
However, some programs have fixed settings that can't be changed; and example of this type of program is AutoCAD, Ventura Publishing, and others. Some of these programs such as Ventura, can be setup to use the parallel port and redirect the output with the DOS MODE command. For the rest of these programs this method will not work; in these cases, you must set the serial port of your computer to exactly match the setting of the Porter's port that you will be using.
If you have a parallel Porter, you don't need to worry about serial protocols and redirection. You should install your software package(s) to use the parallel port when printing. It will also be useful to put the following statement in your AUTOEXEC.BAT file:
MODE LPT1:;;P
This statement will set the parallel port for infinite retry.

You should have received the Porter switch unit and a power adapter that connects to the rear of the unit. You should have the necessary cables, supplied separately, to interconnect the Porter with your other equipment. Ensure that the power switch is in the off (out) position. Connect the AC power converter to a power outlet. Connect the other end to the power input on the rear of the Porter.
Using the cables as described below connect your computer to the port labeled "0" on the rear of the Porter. Connect your peripheral devices to the numbered ports on the rear of the Porter.
Since industry standards vary regarding RS232 cabling, caution must be observed when interconnecting your equipment with the Porter. Generally 5 signals or less must be connected. They are receive, transmit, signal ground, busy in, and busy out. Porter's RxD (pin 3) must be wired to the equipment transmit and Porter's TxD (pin 2) must be wired to the equipment receive. Porter's signal ground (pin 7) must be connected to the equipment signal ground. Busy in and busy out are not required when sing the X-on/X-off protocol. When X-on/X-off is not used, busy out of the equipment must be wired to DSR (pin 6) of the Porter and busy in of the equipment must be wired to DTR (pin 20) of the Porter.
Busy out on the equipment is required to prevent the Porter from sending more data than the equipment can handle. Conversely, busy in on the equipment prevents the equipment from sending more data than the Porter can handle. While the Porter is capable of handling data bursts at maximum baud rates, if it can not resend the data received as fast as it gets the data, due to the equipment being busy and the input buffer being full, then busy in on the equipment must be used. Consult your equipment manual for information on pin numbers of your signals. Several popular cable pin outs are given in Appendix B.
Additionally the Porter's RTS (pin 4) will be high when the Porter is powered on and may be used to monitor whether the Porter is connected to your equipment. Refer to Appendix A for further Porter pin out information. Refer to Appendix B for cable pin out information. If you have a Porter with the /422 (RS-422) option, refer to Appendix A.
For a parallel unit the computer to Porter cable is the same one that would normally connect to your printer. The Porter uses industry standard female Centronics connectors the same as used on most parallel printers. So, instead of connecting your computer cable t your printer, connect it to the port on the rear of the Porter labeled "0". Parallel Porter to printer cables should have 36 pins male Centronics connectors at each end. Connect these cables from your printers to connectors numbered 1-8 on the rear of Porter.
