10.8 Communications specifications
A datalogger is normally part of a two-way conversation started by a computer. In applications
with some types of interfaces, the datalogger can also initiate the call (callback) when needed. In
satellite applications, the datalogger may simply send bursts of data at programmed times
without waiting for a response.
Ethernet Port: RJ45/ jack, 10/100Base Mbps, full and half duplex, Auto-MDIX, magnetic isolation,
and TVS surge protection. See also
Ethernet communications option (p. 19).
Internet Protocols: Ethernet, PPP, CS I/O IP, RNDIS, ICMP/Ping, Auto-IP(APIPA), IPv4, IPv6, UDP,
TCP, TLS, DNS, DHCP, SLAAC, SNMPv3, NTP, Telnet, HTTP(S), FTP(S), SMTP/TLS, POP3/TLS
Additional Protocols: PakBus, PakBus Encryption, CPI, SDM, SDI-12, Modbus RTU / ASCII / TCP,
DNP3, NTCIP, NMEA 0183, I2C, SPI, custom user definable over serial, UDP
Data File Formats: TOA5, TOB1, TOB3, CSV, XML, JSON, binary, encrypted
USB: Micro-B device for computer connectivity

Description
1 5 Vdc O 5 Vdc: sources 5 Vdc, used to power peripherals.
2 SG
Signal ground: provides a power return for pin 1 (5V),
and is used as a reference for voltage levels.
3 RING I
Ring: raised by a peripheral to put the CR1000X in the
telecom mode.
4 RXD I
Receive data: serial data transmitted by a peripheral are
received on pin 4.
5 ME O
Modem enable: raised when the CR1000X determines
that a modem raised the ring line.
6 SDE O
Synchronous device enable: addresses synchronous
devices (SD); used as an enable line for printers.
7 CLK/HS I/O
Clock/handshake: with the SDE and TXD lines
addresses and transfers data to SDs. When not used as
a clock, pin 7 can be used as a handshake line; during
printer output, high enables, low disables.
