Chapter 6: Peripheral Devices & Accessories
Portable Docking Module (PDM)
Figure 6.2 PDM Ports And Connectors
The interfaces available on the PDM are as follows:
• DC power jack (15VDC @ 2.5A)
• Type A USB host port (for connection to USB devices such as a mouse,
keyboard, printer, etc.)
• Type B USB device port (for connection to a USB host such as a PC)
• RS232D DE9 serial port (for connection to a PC COM port or a serial
device such as a printer)
The standard Psion Teklogix PDM kit (PN HU4001) includes the necessary DC
power supply, USB cables and RS232D 9-pin cable.
Use only the recommended adaptor with the PDM – it includes transient
suppressors that protect your 7530 G2 from damage.
The PDM contains reverse polarity and over voltage protection. If the DC power
jack is wired backwards or exceeds 20VDC, the PDM shuts down to protect the
7530 G2, the PDM and the power supply from damage. Psion Teklogix does not
recommend substituting the DC power supply provided with your PDM.
The DC power supplied by the PDM is sufficient to operate the 7530 G2 and fast
charge its internal battery at the same time. The 7530 G2 can run from a PDM
without a battery installed.
