Initial Setup 2-3

Analog Input/Output Connections
The TransPort provides one 4-20 mA or 0-20 mA current output
and two 4 to 20-mA analog inputs with switchable 16-V supply
for loop powered temperature transmitters. Connect the inputs/
outputs using a LEMO® multi-pin connector as shown in Figure
2-1. The pin numbers for the connector and the color code for the
standard input/output cable are shown in Table 2-1.
Note: If your unit has a 5-pin connector instead of an 8-pin
connector, use pins 1-5 in Table 2-1 above for cable
assembly.
RS232 Communication Connections
The RS232 communications port provides a serial interface in
order to connect a printer, terminal, computer, or other
monitoring device. The RS232 cable connects to the TransPort
with a 6-pin phone-type jack. Connect the RS232 cable to the
appropriate location as shown in Figure 2-1. GE Panametrics
supplies the appropriate cable; however, this does not guarantee
compatibility between the device and the TransPort. To verify
that a particular device is compatible, compare the serial port
wiring information in Appendix C to the information given in the
operator’s manual for the serial device. If there is a wiring
compatibility problem, contact the factory for a special cable.
