reporting or SNMP monitoring and management supporting the DDS specific and
TxPORT enterprise MIBs as listed in Appendix A.
Direct Connection
The SLIP port connects to a terminal server or router that provides SLIP access to
the LAN. The TCP/ IP connection is always up in this mode. You must use an
RS-232 to terminal cable connection (9-1001-073-2).
Figure 2-2 Terminal Connection Pinout Assignments
Dial Connection
In this mode, a modem is connected to the SLIP port allowing you to initiate a
SLIP connection to the unit from remote sites whenever access is desired. The
modem should be configured to ignore DTR, enable auto answer, inhibit command
echo, and return verbose result codes. Also, when the unit has alarm messages to
transmit, it dials out of the port using the phone number programmed in the
Management Ports screen on page 45. When a connection is made, the unit outputs
the ASCII characters stored in its buffer. If a phone number is not programmed, the
unit never dials out but you can dial in. The IP connection must be changed to the
SLIP port in the TCP/IP screen on page 42. The SLIP and LAN port cannot both
be active at the same time. You must use an RS-232 to modem cable connection
(9-1001-091-1).

SUPV
The SUPV port is an 8-pin modular jack (electrically RS-232) DCE port configured
for 8 bits, no parity, and 1 stop bit. The SUPV port bit rate can be set through the front
panel interface to 1200, 2400, 9600, or 19,200 bps. Figure 2-2 provides the direct
connection pinout assignments. Figure 2-3 provides the dial connection pinout
