Ports 1 and 2 are System Setup Ports, which are used for communication during
set-up and configuration. Note that Supervisor Level command access cannot be
disabled at these ports.
●
Ports 1 and 2 can either be connected to a PC or modem. Connection to a modem
allows control by a remote PC.

Option Switches: A bank of eight DIP switches, which are used to set the default baud
rate, handshake, message type, and duplex mode. Option Switch functions are described in
Section 4.2

3. Getting Started
This section provides a brief overview of basic CMS capabilities, and describes simple tests that
can be used to determine if the unit is operating properly.
3.1. Communication Parameters
The Option Switches, located on the instrument back panel, select default operating settings.
Switch functions are summarized in Section 4.2, and on a label on the CMS unit.
When the unit is shipped from the factory, the Option Switches are set for 9600 baud, 8 Bits-No
Parity, RTS/CTS handshaking, verbose response, and command echo ON (all switches Down).
For this overview only, use the default switch configuration. Set your communications program
(e.g. ProComm©) to the parameters listed below. After completing this overview and installing
the unit, please refer to Section 5 for instructions on selecting faster communication speeds and
other parameters.
9600 Baud

Using Other Parameters for this Overview (Optional):
If desired, the CMS can match the parameters used by your communications program. Refer to
Section 4.2 and configure Option Switches accordingly. After changing the switches, reset the
CMS; press and hold both the SET and CLEAR buttons, release only CLEAR, wait for the Port
LEDs to flash, and then release the SET button.
Note:
If Option Switches are changed, new settings will not take effect until the
unit is reset.
