1. The power cable or an optional AC power pack plugs into this connector to power the PTC. Two types of power cables are available:
a 12-72 VDC power cable (for non-freezer units without a WAN radio or for freezer units) and an 11-20 VDC power cable (for non-freezer
units with a WAN radio). The PTC's power range is identified on the unit below the power connector.
2. This 11-pin port connects the PTC via cable to standard RS-232 serial devices such as printers and modems. See
3. This connector allows you to connect a PC/AT keyboard to the PTC. See
4. This connector allows you to connect a laser scanner to the PTC. See
5. If your PTC contains two radios, the antenna for the ARDIS radio or MicroRadio plugs into this connector. If your PTC does not contain two
radios, this area of the PTC may house a parallel port, which can be used to connect the PTC to standard parallel devices such as printers. See
page 37
for instructions on connecting a parallel device.
6. The desiccant cartridge absorbs moisture in the PTC when the unit is used in a freezer environment. The cartridge should be replaced when
its window changes from blue (dry) to pink (saturated). Follow the instructions on
