1. Introduction The CAS-161A Code Activated Switch enables a single RS232 Control port to switch between 16 to 64 ports via an ASCII code sequence. The code sequence is a user-selectable Prefix code and a Port Select code. The Prefix code is set via the Setup switch on the bottom of the unit. For added security , the Setup switch can be set to requ[...]

2. Unit Description 2.1. Front Panel Indicators À PWR: (Power) Indicates power to the unit is ON. Á TXD: (T ransmit Data) Indicates data is being transmitted out pin 2 of the Control port (MODEM Port). Indicates data is being received at pin 2 of the selected port. Â RXD: (Receive Data) Indicates data is being received at pin 3 of the Control po[...]

2.2. Back Panel Components À Input Port s1-1 6 : Ports labele d1-1 6a r e 25-pin, female, RS232 connectors. Optional RS422 connectors can be factory installed to increase data transmission distance. For a description of the port interface, please refer to Appendix A. Á MODEM Port (Control Port): A 25-pin, female, RS232 connector . For a descripti[...]

3. Installation 3.1. Configure SetUp Switches There are two banks of DIP switches located on the bottom of the CAS-161A unit. These switches are used to configure the Prefix Code (command character), enable the Broadcast Mode, and select the baud rate. Switch functions are summarized on the bottom of the unit and in the sections that follow: Note: [...]

3.1.1.3. Baud Rate Select (Sw6 - Sw8) Selects the operating baud rate; from 150 to 19.2K baud. Baud Rate Switch (Bank 1) 678 * = Factory Setting 3-2[...]

3.1.2. SetUp Switch Bank 2 The bank of DIP switches located closest to the front panel are used to select the Prefix Code character and set the parity . 3.1.2.1. Prefix Code (Sw1 - Sw7) As mentioned previously , the Prefix Code informs the unit that the next character will be a command. The Prefix code can be any ASCII character . However , since i[...]

3.1.2.2. Parity (Sw8) Parity can be set to Even, Mark, Odd, None, or Space. Parity Switch 8 (Bank 2) 1 (On) 0 (Off) 3.2. Connect Power Cable 1. Make certain the power switch is in the OFF position. 2. Attach one end of the power cable to the AC power connector on the CAS-161A. Attach the other end to a grounded wall outlet. 3.3. Connect Data Cables[...]

4. Port Selection 4.1. Selecting a Port 1. After completing the installation procedure, flip the power switch on the back of the unit to ON. Note: Upon each power-up the unit will reset and all ports will be closed. 2. Refer to the Port Select Code Chart below and find the letter representing the port you wish to connect to. Module 1 Module 2 Modul[...]

Examples: Assume the Prefix Code is ^V and the Prefix Code Repetition V alue is 4. T o connect to Port 14, use the following command: ^V^V^V^VM Assume the Prefix Code is ^Y and the Prefix Code Repetition V alue is 1. T o connect to Port 44, use the following command: ^Yk 4.2. Closing/Opening All Ports 1. T o close all ports at once, enter the Prefi[...]

B. Printable Prefix Codes Since the Prefix code is transmitted through the opened port, it is best to select a non-printable Prefix Code. The procedure for selecting the Prefix Code is described in Section 3. If your application requires a printable code, refer to the ASCII code chart below . Remember: · Switch position s1-7 correspond to ASC bits[...]

C. Installing Add-On Modules The CAS-161A is field expandable to 32, 48, or 64 ports by attaching up to three additional Add-On Modules to the master unit. Each Add-On Module Kit includes the following: · 1 ea. Add-On Module w/ six-wire power cable · 2 ea. Connecting Plates · 1 ea. Left Rack-Mount Bracket (Style-2) · 1 ea. Right Rack-Mount Brac[...]

1. Remove the instrument top cover . If your unit has a stand-alone top cover , remove the cover; the stand-alone cover is no longer required. If your unit has a Rack-Mount Kit, remove the Rack-Mount Cover , Left and Right Rack-Mount Brackets (Style 1), and screws. Save these parts, they will be used later . 2. Locate and unroll the ribbon cable (A[...]
